Red-bellied Woodpecker can use its bill to obtain insects from just below the bark surface, employing an action like a pickax, to obtain invertebrates that bore into wood and are out of reach of other birds.  What many people don't realize, however, is that they often use their bills in more subtle ways first, tapping to detect where bark in worn and where there may be hollow chambers inside. 

  
   Throughout the year the hard, heavy tapping is used to make cavities for nesting and roosting.  It can take up to 3 weeks to create a single hole.  The tapping is also put to good use to advertise for and attract a mate.  The so-called "drumming" is not, as many people think, the sound of excavation of a hole, but it is actually the knocking of the bill against a suitably sonorous piece of wood simply to make a signature noise.  (Extreme Birds:  The world's most extraordinary and bizarre birds, 2008, Dominic Couzens)
 3. 
The species account in Birds of North America Online says the pair bond lasts about seven months, through the nesting season, and it is "rare to find mated pairs from September through January." It mentions that both sexes excavate cavities for roosting, and both sexes change roost sites frequently, but says "adults roost singly in cavities at night," and does not describe pairs working together on roost holes.

   Hempstead Lake State Park (direction)
   camera: GH2 + 100-300mm lens

Restroom beside the park office is open.  More than 10 (even 20) Hooded Mergansers, Gulls (some Great Black-backed Gulls), Mallards, 2 Mute Swans (one is juvenile; another is the mother?), etc.  Robin and probably Hermit Thrush (saw clearly but no photo).

Info:
   
There are numerous winter records of the hermit thrush in southern New England, where it has been reported in favorable situations throughout Massachusetts and Connecticut even at times when it was very cold and the ground covered with snow. It has also been reported from various sections of New York and New Jersey during the winter months. South of this area it is a regular winter resident.  src

   Kissena Park
   camera: GH2 + 100-300mm lens

   Hooded Mergansers still here, many males courting a female with display; I encountered them in closer distance than before.  So do Shovelers.  I saw 1 male going after a couple and another male is in a not so far distance.  I think these 2 are not their sons but males failed to form pairs.  The couple tends to do sieving together and the other 2 males form another team.  Got a lot good pictures and videos of both species.  What a Christmas banquet of ducks!
   A
few of White-throated Sparrows beside my car; no sight of Double-crested Cormorant and Great Blue Heron; all Ring-billed Gulls (not see other gulls).
   After the p.m. walk, we went grocery shopping.  Before leaving the Chinese supermarket at about 4 p.m., we saw a Nissan van with a broken right-sided back-seated window.  The African American lady called the police and mentioned that she just left the van for about 10 minutes in the parking lot.  That means within a short period of time, her stuff become someone's Christmas gift.  This is really a crazy holiday.  Be alert while doing Christmas shopping.

Ring-billed Gull nesting colonies normally include a small percentage of two-female couples. Fertilized by an obliging male, each female spouse lays a clutch of eggs, leading to 5–7-egg "superclutches."  (Normal is 2–4 eggs)

Info:
(1)
The Hooded Merganser finds its prey underwater by sight. The merganser can actually change the refractive properties of its eyes to enhance its underwater vision. In addition, the nictitating membrane (third eyelid) is very transparent and probably acts to protect the eye during swimming, just like a pair of goggles.  cool facts   more
(2) Hooded Mergansers are not considered to be the most graceful while on land, but they are quick flyers. They take off by running on top of the water, and with wings flapping continuously until they are airborne. While in the air, they are extremely fast and agile flyers weaving through their forest habitat until reaching their destination. They also land fast onto the water, skiing across it until they stop. The Hooded Merganser are not only agile in the in the air, but exceptional divers and swimmers. When diving, they fold their wings close to the body and use their feet to propel them through the water.  src 
(3)
During the breeding season, breeding males display a wide variety of ways to attract potential mates. The Hooded Merganser is extremely vocal letting out a frog-like croak, which can be heard a half mile away. They may also display their crest, which will invite the receptive female to mating with them. A head-throw, is a common display during courtship. During a head-throw a drake will swim parallel to a female with his crest fully erected as he passes the female, he throws his head back quickly until it reaches his back. Then, he slowly raises his head forward while letting out his frog-like voice. The female responds by either ignoring his postures or accepting it by bobbing and pumping her head. The female may also display her receptiveness by stretching her neck and head just above the water and flattening her tail on the waters surface.  src  
(4)
Most ducks confine their displays to the water (or land) surface, since their heavy weight relative to their wing area ("high wing loading") dictates continuous flapping and makes complex maneuvers, such as hovering and soaring, difficult or impossible.   src
(5) Ring-billed gulls begin breeding at 3-4 years of age.  src

Double-crested Cormorant

Note:
  
(1) Northern Shovelers feed by dabbling for plant food, often by swinging its bill from side to side and using the bill to strain food from the water. They use their highly specialized bill (from which their name is derived) to forage for aquatic invertebrates - a carnivorous diet. Their wide-flat bill is equipped with well-developed lamellae - small, comb-like structures on the edge of the bill that act like sieves, allowing the birds to skim crustaceans and plankton from the water's surface. This adaptation, more specialized in shovelers, gives them an advantage over other puddle ducks, with which they do not have to compete for food resources during most of the year.  wiki
  (2) close-up picture of Northern Shoveler's bill showing the lamellae - treknature.com    mirror

  (3)
The unique bill morphology of Northern Shovelers allows this species to exhibit one of the most unusual feeding behaviors of any duck. Its large spoon shaped bill is adapted for sifting large amounts of muddy water. Their tongues are highly specialized with extensive comb-like teeth called lamellae, which help filter food items from the water. Moving its head side to side, water is drawn in at the tip of the bill, filtered through the lamellae to pick up any food particulate and then expelled at the base. The breeding season for Northern Shovelers begins on the wintering grounds in December, where courtship of hens by a group of drakes commences. By January, the majority of individuals have paired before they start their spring migration and most return to the same breeding grounds they used the previous year.    src
  (4) Shovelers are specialized for the time-consuming
process of sieving plankton from the waters of small, permanent ponds. A male defends a small, discrete territory around his mate, with whom he has a strong, long-lasting relationship; consequently he rarely spends time in "extramarital" pursuits.  Unlike relatively sedentary shovelers, pintails (again, a member of the genus Anas) range far and wide to forage in temporary bodies of water, and tend to nest in sparse cover at a great distance from water. In addition, male pintails spend only part of their time with their mates, and devote some of their time trying to copulate with other females; as a result female pintails tend to be frequently harassed. It seems likely that close defense of a territory is profitable for the male shoveler because concentrated food resources allow him to provide an area where his mate can obtain sufficient food free from harassment. No such strategy is feasible for the male pintail because of the dispersed nature of that species' food resources. Therefore Northern Pintails and their relatives (e.g., Green-winged Teal) have not evolved a conspicuous long-range territorial threat display; they need only guard nests and mates, not feeding territories.    src

Notes:
(1) After the breeding season, Common Grackles form large foraging flocks that often include other blackbirds and cowbirds. Flock size increases as birds from the northern part of the range migrate to winter destinations in the southeastern United States, from the Carolinas to the Gulf Coast. In flight, the flocks tend to be as broad as they are long, unlike the long and cylindrical flocks of Red-winged Blackbirds.  src

(2)
  Q: I saw a large flock of grackles heading directly east on August 10. Were they starting their fall migration?  I also saw large flocks of starlings in August. Does that early migration mean that we will have a cold winter?
  A: As for the flocks of grackles moving in a given direction in early August, that was not migration. Grackles never start their migration until late October. Each species migrates at the same time every year to within a week. The timing is governed by their hormones which in turn are stimulated by the shortening of the daylight hours in the fall. The date they start to migrate is not due to a lack of food, nor to some sense that the winter will be severe. It depends on the sun and that does not change. It is quite normal for starlings and grackles to gather into flocks after the nesting season is over. Each species gathers into its own flock to forage for food and especially to roost together with their own kind at night.   src
(3) The name green bottle fly (or greenbottle fly) is applied to numerous species of blowfly, in the genera Lucilia  and Phaenicia (the latter is sometimes considered a subgenus of the former).   The maggots (蠅蛆) of this fly are known to preferentially consume dead tissue while leaving live tissue intact, and so have been sold for use in maggot therapy.  Forensic importance: These flies are known to lay eggs in cadaver tissue (屍體組織) in the wild within hours after death. The developmental stage of their larvae in the cadaver can be used to accurately predict the time death occurred.    wiki   Common Green Bottle Fly (Lucilia sericata)  Common Flies   Handbook of urban insects and arachnids  By William H. Robinson
(4) blow / bottle flies - Representative Species:
 The bluebottle flies (Calliphora vicina and Calliphora vomitoria), measure 1/4 to 9/16 inch long and have a dull bluish-black thorax and a shiny metallic dark blue abdomen. 
Many guide books on insects show pictures of Bluebottle Blowflies that are actually not Calliphora vicina, but rather Calliphora vomitoria. However C. vomitoria is a very rare species. Usually the Bluebottle Blowflies commonly found in gardens and sometimes indoors is C. vicina src  pic of C. vicina  wiki   buggguide.net   pic of C. vomitoria 
C. vicina is distinguished from the commonly known C. vomitoria by its bright orange cheeks.  So the pictures shown as here is actually C. vicina .
C. vicina: yellow-orange jowls with black hair; C. vomitoria: black jowls with predominantly reddish hair. Note: jowl: The lower part of a person's or animal's cheek, esp. when it is fleshy or drooping.
 The bronzebottle fly, Phaenicia pallescens (formerly Phaenicia cuprina), are 3/16 to 3/8 inch long with a shiny thorax and abdomen that are colored metallic bronze. 
The greenbottle flies (Lucilia illustris and Phaenicia sericata), range about 1/4 to 3/8 inch long and have a shiny metallic green thorax and abdomen without stripes. Green Bottle Fly

Note:
  Reversing at 42mm gives magnification greater than Raynox 250 on 100mm.  Despite of MF, I get some pretty sharp pictures, to my eye its sharpness is like using Raynox on 100mm with 1-area-AF.  Reversing at less than 42mm is more likely to give less desirable results because of the shallow DOF caused by greater magnification.  But it still causes quite dramatic vignetting.  Try Nikon 5T (1.5 diopters, thread/size is 62mm)  which somebody got excellent results (src).   I think the size of Raynox is only 43mm so using on 67mm lens will cause vignetting. (not necessary, I got quite good result @ 100mm using 23-area AF on 10/23).   Nikon 5T will be better.  But the best result is Nikon 5T on 14-140mm lens.  Canon 500D (2 diopters) has 72mm thread so I can use 67-72 step-up ring to mount it.  Note: for the 14-140 with the 5T mounted, the distance to subject focal length is around 36" to 18" you can still AF easily...where the 100-300 and 45-200 with Panasonic DMW-LC55 (thread is 55mm) or Canon 500D are limited to 12-24".  So the best for low-level magnification (2 diopters or less) is 14-140 + 5T.  And But Nikon 5T is cheaper even more expensive in eBay since not produce anymore.  New Canon 500D is quite expensive.  Buying Panasonic Elmarit Leica DG Macro - 45mm f/2.8 instead of a new Canon 500D 72mm ($300 as of 10/31/2011) or an used for $100.
  The diopter of 100-300mm lens + 5T =  1/1.5m + 1.5 (diopter) = 2.167 ; the new focus distance - 1/2.167  = 0.46m, pretty good.  For Canon 500D is even shorter (0.375m or 1.2').  And above say AF will work at 12-24" on 14-140mm so I expect similarly on 100-300mm (perhaps 15-30"?).  So Canon 500D 72mm will be a great macro lens for 100-300mm, esp. shooting at 300mm with a distance (2-3 feet).
  Canon Close-Up Lens 500D is a double-element accessory that attaches to front of lens. It changes closest focusing distance from infinity to 500mm (approx. 19.7" from front of lens).
  A working setup with Olympus RF-11 Ring Flash (expensive and don't forget an external Panasonic-compatible flash unit is need) is:

Panasonic Lumix G 100-300mm F4-5.6 OIS Lens
Kiwifotos LA-67HX100T Lens Adapter (rear part only)  ebay - new for $25 + free shipping
67-72mm Step Ring

   http://forums.steves-digicams.com/panasonic-micro-four-thirds/190854-g3-100-300-500d-rf11-close-ups-macros.html
  Since the RF11 doesn't allow room to screw the 500D on, you have to install kiwi adapter to allow the 500D to be installed...a larger setup but works a charm... 
  Raynox 250 will be still useful for 14-42mm lens & FZ35 (with 46-43 step-down adapter).
  Step-up ring can be used to prevent vignetting. Sometimes a filter can produce vignetting, especially on wide angle lenses. Stacking filters may cause vignetting as well. If using the adapter ring with larger sized filters, the problem may be eliminated as the filter rings are expanded out beyond the lens.  In my case, 43mm Raynox on 67mm 100-300mm causes vignetting.  But using 67-72 step-up ring with 72mm Canon 500D will prevent this kind of vignetting.

10/30 (Sun)  morning after the first snow this year yesterday
 around home

saw a female Ruby-crowned Kinglet (or warbler) with wing bar & whitish yellow belly at the (probably an evergreen coniferous 針葉) shrub (or bush 灌木) behind the "water foundation garden."  Robin.

Note:
  Huge swaths of the north-eastern United States have been hit by a rare October snow storm that struck across the region from Virginia all the way to Maine. Dubbed "Snowtober" by news organizations covering the unusually early winter storm, the massive weather formation dumped up to 30cm (one foot) of snow in parts of the country that rarely see it this early in the year. ...
  In a few parts of the country the storm was an almost once-in-a-lifetime event. New York City has seen measurable October snow just three times since 1869, when America was still recovering from the civil war. But 2011 has been an unusual year for New York weather, as the city was also directly hit by Hurricane Irene just a few months ago. Over New York and other areas the storm was also accompanied by thunder and lightning, another fairly rare event known as "thundersnow".   src
  An unprecedented (for October) 2.9 inches of snow was measured in New York City's Central Park on Saturday. Since snowfall records began in 1869, Central Park has never received an inch of snow on any given October day. The last time that Central Park recorded measurable snow was on Oct. 21, 1952 when 0.5 of an inch fell. Prior to that, 0.8 of an inch fell on Oct. 30, 1925.  src   more on 2011 Halloween nor'easter

SUMMARY

A survey of 40 species of 14 genera of North American wood-warblers (Parulidae) reveals that the head-scratching method employed is surprisingly stable within species. The experiments by Nice & Schantz (1959a, b) induced some normally overwing head-scratchers to scratch the head under the wing. It is suggested that this was because their leg rings became caught in secondaries, making normal overwing head-scratching impossible. A few exceptional head-scratching patterns under different conditions invariably involved normally overwing head-scratchers employing the underwing method, and a few species head-scratch under the wing as nestlings but change to overwing before fledging. In all, 31 species appear to be normally overwing head-scratchers, seven are underwing head-scratchers, one species uses both methods and one remains uncertain. There is no evidence for lateral preference in either head-scratching method, and head-scratching is only loosely linked sequentially to preening. The functional significance of head-scratching may be related to blockage of the eustachian tube, or to cleaning and oiling the feathers. Avian head-scratching is more difficult to homologize with mammalian head-scratching than others have considered it to be, but all evidence suggests that within birds underwing head-scratching is phylogenetically primitive. In wood-warblers, the head-scratching method does not correlate with taxonomy. However, ground-dwelling wood-warblers tend to scratch the head under the wing and arboreal wood-warblers over the wing. This correlation provides the first strong clue to the functional significance of the difference between methods in passerine birds.

     Bald-faced Hornet - also commonly called White-faced Hornet.  The syrphid fly: Spilomyia fusca is a mimic of the Bald-faced Hornet: http://bugguide.net/node/view/33230

    
 Wasps can be divided by their habits into social and solitary types.  Social types are the familiar yellow jackets, paper wasps and hornets, which live in colonies or communal nests, may sting severely and often appear very numerous. ... A far greater number of species of wasps are solitary types, in which each individual leads an independent life.  
     Apart from a few exceptions, solitary wasps are hunters.  The females hunt other insects and store them in burrows or hollow mud cells.  This is not to provide food for themselves, but as a store for their larvae.  The exceptions are the solitary wasps that have a parasitic or "cuckoo" mode of breeding ("kleptoparasites").   So solitary wasps = hunting (predatory) wasps (mainly) + wasps being kleptoparasites (exception).
     Question: giant ichneumon wasp is predatory wasp or not? 
     I think is not "cuckoo"; is predatory although is parasitoid - "most [Ichneumon wasps] are parasitoids—the larvae feeding on or in another insect which finally dies."   wiki
   Definitions and distinctions of Parasitoidy from Parasitism
 
     Potter wasps (or mason wasps) are a cosmopolitan wasp group presently treated as a subfamily of Vespidae, but sometimes recognized in the past as a separate family, Eumenidae. ... All known eumenine species are predators, most of them solitary mass provisioners, though some isolated species show primitive states of social behaviour and progressive provisioning.  So I think solitary hunting wasps are mostly mass provisioning while social wasps are progressive provisioning.  Info: http://en.wikipedia.org/wiki/Mass_provisioning   http://en.wikipedia.org/wiki/Potter_wasp   Solitary Wasps: Cicada Killers, Mud Daubers

Cuckoo Bees and wasps

    There are many different lineages of cuckoo bees, all of which lay their eggs in the nest cells of other bees. There is also a family of cuckoo wasps, many of which lay their eggs in the nests of potter and mud dauber wasps; many other lineages of wasps in various families have evolved similar habits. These insects are normally referred to as "kleptoparasites," rather than as "brood parasites." The distinction is that the term "brood parasite" is generally restricted to cases where the immature parasite is fed directly by the adult of the host, and raised as the host's offspring (as is common in birds). Such cases are virtually unknown in bees and wasps, which tend to provide all of the food for the larva before the egg is laid; in only a few exceptional cases (such as parasitic ["cuckoo"bumblebees) will a bee or wasp female feed a larva that is not her own species. The difference is only in the nature of the interaction by which the transfer of resources occurs (tricking a host into handing over food rather than stealing it by force or stealth), which is why brood parasitism is considered a special form of kleptoparasitism.

Parasitism / Parasitoidy / Predation

In practice it is not always necessary to distinguish parasitoidy from parasitism, nor is it always even possible to do so cleanly. However, when it is appropriate to do so, a typically parasitic relationship is one in which parasite and host interact without lethal harm to the host, and without dramatically reducing the host's reproductive success. In most such relationships, the parasite arrogates enough nutrients or other resources to thrive without preventing the host from reproducing. In contrast, in a parasitoidal relationship the exploiting organism kills or sterilises the host, typically before it can produce offspring. A non-lethal parasite sometimes is termed a biotroph. In contrast, when a parasitoidal relationship is regarded as a form of parasitism, the parasitoid may be called a necrotroph.

[A]t the opposite extreme from parasitism, parasitoidy in turn grades into predation. Differences between various kinds of hunting wasps provide convenient illustrations. Predatory social wasps hunt flies, caterpillars and the like, grab them, butcher them, carry them home and feed them to their young. That is patent predation. Some solitary wasps, such as bee pirates, sting prey, sometimes fatally, before saving it, usually entire, in a nest or burrow for the young to feed on. That too is predation, fairly clearly.


More note (9/2014):
(1) Predators of bees in Southern Africa - (1) Bee pirates : Palarus latifrons – banded bee pirate; predatory wasp; maybe prey on virgin queens?  (2) Bee wolves? : Philanthus triangulum – bee wolf; Yellow bee pirate; mostly on flowers.  Prey on foraging bees.  (3) European wasps : a) Yellow jacket Vespula germanica; present in the Cape for almost 40 years; huge nests; now spreading; does predate on bees. b) Polistes dominulus; found in the Cape in 2009 and spreading rapidly; no records of predation on bees.
(2) Philanthus triangulum: commonly known as the European beewolf or the bee-eating philanthus, is a solitary wasp that lives in Europe and Northern Africa.  wiki
(3) Does anything eat wasps?  a) invertebrates: several species of dragonflies (Odonata); robber and hoverflies (Diptera); wasps (Hymenoptera), usually the larger species feeding on smaller species, such as social paper wasps (Vespula maculata) eating V. utahensis; beetles (Coleoptera); and moths (Lepidoptera).  b) vertebrates that feed on wasps: numerous species of birds, skunks, bears, badgers, bats, weasels, wolverines, rats, mice and last, but certainly not least, humans and probably some of our closest ancestors.
(4) Bald-faced Hornet (Dolichovespula maculata) - Bald-faced Hornets are predators and they attack only live prey. They are mostly predators of spiders, harvestmen, hemipterans, spittle bugs, house flies, sawflies larvae, caterpillars, beetles, other yellowjackets species and grasshoppers. The adults carry their prey or part of them to the nest to feed their larval states. They sometimes feed of flower nectar or sweet substances (Akre et al. 1981, VanDyk 2003).   src

Info:
The life stages (or this link) of the Boxelder bug :

Overwinter as adults. Emerge in mid-spring, mate, and lay eggs. In the spring adults and nymphs will feed on seeds and maple trees. This first generation of nymphs may feed on dead insects including their siblings. These nymphs will emerge as adults in early summer.

In the summer and fall, the adults and nymphs will suck sap from new tree (usually boxelder) growth and may feed on weeds and other plants. This type of plant feeding is usually non-damaging but when they feed on strawberries it can be very damaging. The second generation will occur in late summer and will have adult emergence in October. This generation is the one that will overwinter after the first frost.   src

The Eastern Boxelder Bug is sometimes known as a garage beetle or may be confused with other Jadera spp., especially Western Boxelder Bug ( Boisea rubrolineata ).  The name "stink bug (放屁虫)," which is more regularly applied to the family Pentatomidae, is sometimes used to refer to Boisea trivittata. Instead, these insects belong to the family Rhopalidae, the so-called "scentless plant bugs". However, boxelder bugs are redolent and will release a pungent and bad-tasting compound upon being disturbed to discourage predation; this allows them to form conspicuous aggregations without being preyed on.

Golden rain tree bug (Jadera) is sometimes confused with the boxelder bug.  Jadera haemotoloma is closely related species that is occasionally mistaken for the boxelder bug, but lacks the red lines on wing edges.   And the small milkweed bug & large milkweed bug are seed feeding bugs that resemble the boxelder.  Small Milkweed Bugs and Large Milkweed Bugs have a different pattern of red/orange markings.    Neacoryphus lateralis (or Melacoryphus lateralis) has similar coloration, but red markings are somewhat different - red stripe at neck but no red edges to wing covers.   src-1   src-2   src-3   src-4

Info:
  The most visible physical difference (at a glance) between Eastern carpenter bee and a bumblebee is the abdomen. Eastern carpenter bees have a shiny black abdomen, with the only yellow hair present being at the base next to the thorax, while bumblebees have a very fuzzy abdomen, which in some species has large areas of yellow hair across the middle (this is visible and obvious). The female eastern carpenter bee also has a much broader head than bumblebees. Eastern carpenter bees can be sexed at a glance. Males have a patch of white cuticle on the face, as opposed to females, whose faces are black. Males are unable to sting, since a bee's stinger is a modified ovipositor (an egg laying organ).  wiki

A review on 100-300mm says:

 

... its sharp, very sharp if you nail the focus which is actually not easy at times, especially when handholding a shot.

 

When you are dealing with focal lengths that long, the increased M4/3 DOF is no longer very noticeable and shooting wide open, you have to be bang on with your focus or you’ll see that it’s out. It has the same O.I.S twitchiness as the 45-200, only worse because of its increased magnification. If you are going to shoot handheld at any shutter speeds below 1/1000, you’d better give the lens a moment for its stabilizer to lock on before squeezing off a shot. This lens really demands a tripod, but since it is still so lightweight, there is no tripod ring needed.

 

With regards to using these longer lenses wide open and trying to achieve a precise point of focus, I’ll mention that the GH2 body can sometimes be frustrating in its seeming insistence in focusing on things that are clearly outside of the displayed AF rectangle in the viewfinder. This is very “DSLR like” in some respects and unnecessary since there is no reason why the AF rectangle couldn’t exactly match the actual focus area that is used. More on auto-focus performance, and some of its quirks, especially with long lenses, in my upcoming GH2 body review, which will appear in a new blog entry as “Part 2” of my Panasonic review.

 3. Common Buckeye (Junonia coenia, described by Jacob Hübner in 1822) (= Precis coenia) - Males perch during the day on low plants or bare ground to watch for females, flying periodically to patrol or to chase other flying insects. Flight: Two to three broods from May-October.   Passing through New York, heading south (so will see it in September).  Their southbound autumn flight is particularly noticeable along the coasts where at times they seem to be everywhere.  Every spring some of them return to repopulate the northern United States and parts of Canada.  Buckeye butterflies appear in different forms in different seasons.  Underside of hindwing is brown or tan in the wet season (spring/summer) form and rose-red in the dry season (autumn) form.  The change is probably linked to lower temperatures and shorter days. The difference is so pronounced that scientists call the forms by different names -- linea for the tan one and rosa for the other.      src1   src2   src3   src4   wiki

 6. Green Heron is the best fly fisher (cunning & patient) : 
      Adopting an almost horizontal posture, a green heron prepares to lunge toward a fish beneath a lily pad.  Within seconds it will make a grab -- aided by a special arrangement of the vertebrae that enables the neck to "snap" forward -- and will soon have the fish wriggling in its jaws. 
      All over the world, other species of heron practice the same technique, and at first sight there seems nothing unusual about what this green heron is doing.  There is, however, a very big difference.  In many ways the green heron has more in common with a human angler than any other species.  It regularly uses bait to lure the fish within its reach.  Using tools is a rarity among birds, but the green heron, along with several very close relatives in other parts of the world, is known to place a variety of different objects into the water in front of it then lunge at fish attracted to the lures.
      Green herons have recorded using sticks, feathers, bread, captured insects, flowers and corn.  All of which have been picked up from the edge of water and dumped onto the surface.  American birds have been seen to use popcorn.  Clearly some of these are edible items, but feathers and sticks act as "dry flies" of no nutritional value that are sufficient to fool a fish.  Interestingly, some green herons snap twigs off waterside vegetation to produce their bait, a rare example not just of using tools but of making tools, too.  (Extreme Birds:  The world's most extraordinary and bizarre birds, 2008, Dominic Couzens, p.155)

Subject: NYC: Riverside Park Drip - Open For Business
From: Ben Cacace
Date: Wed, 31 Aug 2011 22:47:52 -0400

I just spoke with Jeff Nulle and he wanted to let you know that the Riverside Park (Manhattan) Bird Drip has been turned back on today.

This is from Phil Jeffrey's "Birding Wiki" on Riverside Park:

http://www.nycbirds.com/wiki/index.php?title=Riverside_Park  (more on NYC Birding Wiki)

"The Drip" is an area under some rocks where water is piped in. Birds like to drink and bathe in it. Many others hang around in the trees and bushes near by. It is great because it allows for good and fairly close views of warblers at ground and eye level - not just high up in the trees.

The closest entrance to the Drip is at 120th Street across from Riverside Church. Go down the stairs at the "Forever Wild" sign, turn right and go down those stairs. The tennis court will be on your right. Turn left and walk toward the fenced-in area which will be on your left.

 Solitary Sandpiper

Info:
Eastern Forktail (Ischnura verticalis) is a member of the damselfly family Coenagrionidae.  The males are yellow-green with blue on the top of the eighth and ninth abdominal segments.  size 1.1"  Thorax black above, with green shoulder stripes; pale green sides.  Abdomen mostly black, with blue tip (segments 8 and 9) and thin pale tings; black spots on sides of blue tip.  Eyes dark above, greenish below, with small green eyespots.  What I saw at Kissena Park behaved like Emerald Spreadwing: (1) weak/slow flight and brief;  (2) wings held partially spread when perched.

Solitary Sandpiper often by itself at sheltered ponds; seldom associates with other shorebirds; never in large groups. When worn, upperparts and breast-sides quite dark, with most white markings worn off.

*More like a female Mallard because of whitish tail & light brown body. American Black Duck has a darker body & dark tail.
Or a hybrid female Mallard X American Black Duck because it has a dull greenish gray bill (like female American Black Duck) with little marking (like male American Black Duck)
Or immature Mallard or American Black Duck.

By November, the Starling has completed its preformative molt and has attained its formative plumage. ... By late summer, the now one-year-old bird is beginning to grow new feathers which push out the old, worn feathers.  This is the second prebasic molt (the first prebasic molt having taken place in the nest)."

 Andromorph (male-like) form vs. heteromorph (female-like) form.  Google : "female polymorphism".

Female-limited polychromatism is found in many species of Odonata. Half the European genera of Zygoptera show this polymorphism, which is especially common in the family Coenagrionidae where 65% of the species are polymorphic (Cordero & Andrés, 1996).
As in butterflies, where this type of polymorphism also occurs (Clarke et al., 1985), one of the female morphs is very similar to the conspecific male, whereas the other phenotypes differ in coloration. The different morphs have been given various names in the scientific literature. Because the differences among morphs involve their colour only and not their morphology, this paper will use the terminology proposed by Hilton (1987) and shortened by Cordero et al. (1998), using 'androchrome' for male-like females and 'gynochrome' for those females with a different coloration.  src

...

The three of us, joined by Bob Kurtz, then worked the south end and up the
east side of the East Pond. If you understand that you're going to get wet,
you can make it a good distance past the raunt. A problem not always
mentioned is that with little shoreline, you can't avoid disturbing all the
birds along the way. Be that as it may, we eventually found both HUDSONIAN
GODWITS and 1 MARBLED GODWIT spending their morning on the west side of the
pond, a good distance north of the raunt. No White Ibis to be seen. Both
Marbled Godwits were later found at low tide on the bay, north of the dike.

 Periodical cicadas exist in only one place in the world: the eastern United States.

 World's largest cicada brood begins hatching in the South (The Great Southern Brood) 
 Great Eastern Brood (Brood X)—The Great Eastern Brood has a 17-year cycle and has emerged in 2004. This brood is found only in Vermilion, Edgar, and Clark counties and a small section of Champaign County and occupies an area that supports other relict eastern species such as American beech and tulip poplar. Brood X also occurs in Delaware, Georgia, Indiana, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia. They will emerge again in 2021.  src
 2013:  The East Coast Brood - CT, MD, NC, NJ, NY, PA, VA.  

 Periodic cicadas are found in eastern North America and belong to the genus Magicicada. There are seven species, four with 13-year life cycles, and three with 17-year cycles. The three 17-year species are generally northern in distribution, while the 13-year species are generally southern and mid-western. Periodic cicadas generally emerge in May and June, apparently when the soil temperature reaches 64° Fahrenheit (18° Celsius). This means that emergences in southern and low-lying areas occur earlier in the summer than in the cooler northern locations.  src  mirror

Jamaica Bay Wildlife Refuge (JBWR) West Pond

dragonfly: Blue Dasher (like the one seen on 5/29 Staten Island) in obelisking position
butterfly:  black morph of female Eastern Tiger Swallowtail (Papilio glaucus) or female Black Swallowtail?, small silver-white butterfly (Small White?)
other insects / animals: Bumble Bee (not Carpenter Bee), Syrphid Fly? , Turtle
bird: Starling, Mourning Dove, Robin, Towhee, Tree Swallow, Song Sparrow, Wren, Mockingbird, Catbird, Brown Thrasher, RWBB, Skimmer, Oystercatcher, Common Tern, Canada Goose, Glossy Ibis, Great Egret, Snowy Egret,  Common Yellowthroat, (White-rumped?) Sandpiper or Ruddy Turnstone, Laughing Gull and other Gulls, Swan, Osprey, Cormorant.  (at least 25 species). 

Not sure, not seen or not pay attention:  Crow, Grackle, House Sparrow, Yellow Warbler, Least Tern?, Cardinal?,

The 2 juvenile ospreys stay at the nest while the other one (probably is the eldest one who fledged already) and parents are not there.  When will these 2 young one spread their wings?

I saw the shorebird digging in sand so probably it is a Ruddy Turnstone (legs and feet are orange).  Least Sandpiper has yellowish or greenish legs.  Semipalmated Sandpiper has blackish legs. Probably not White-rumped Sandpiper.  I can't see clearly the leg color nor white rump or not.

 Osprey:  魚鷹試飛成功 順利降落, 另外兩隻唔好再瞓啦, 振翅起來吧!

   Large swaths of oyster reef once lined the bottom
of the Hudson-Raritan Estuary (河口),
cleaning the water and providing
a source of food. Overfishing through the
19th century, the release of untreated sewage
into waterways, and other ecological disturbances
have virtually eliminated the habitat of
this keystone species. Today there are no major
naturally occurring oyster reefs in the region,
though scattered oysters remain. "Oysterculture"
has been gaining momentum in recent
years as evidence suggests that oysters aid in
the restoration of bottom-sea habitat and the
filtering of the water column.
   Many small-scale restoration projects have
been undertaken in recent years. These projects
include efforts by NY/NJ Baykeeper, which
depend on citizen stewardship to seed and
monitor oyster populations. The Bronx River
Oyster Restoration Pilot Study by DPR was
successful, and the Department of Environmental
Protection (DEP) has placed an oyster
bed and reef balls in Jamaica Bay to evaluate
oyster growth, survival, and reproduction as
well as water quality and ecological benefits.
The findings of this pilot study will inform future
atteattempts to restore oyster habitat in the Bay.  src

NYC airport invaded by turtles, delaying flights

About 150 turtles crawled onto the tarmac at New York's Kennedy airport Wednesday in search of beaches to lay their eggs, delaying dozens of flights, aviation authorities said.

The migration of diamondback terrapin turtles happens every year at Kennedy, which is built on the edge of Jamaica Bay and a federally protected park. In late June or early July the animals heave themselves out of the bay and head toward a beach to lay their eggs.

Marine Nature Study Area, Oceanside 20 May

Joe Giunta and I (Sy Schiff) joined by George Form, Debbie Martin and Joe 
Viglietta spent the morning looking at marsh birds. Arriving before the Spring 
high tide, the water helped push the marsh birds out of the cuts and into the gher areas. CLAPPER RAILS were widely scattered (we saw at least 6), calling 
and walking about. 

Both SALTMARSH and SEASIDE SPARROWS were singing and we had brief but 
satisfactory views of both species. 

But the best was a WHIMBREL that only Joe G. and I got to see before it walked 
behind the vegetation at the edge of the marsh and could not be relocated. 

Other birds of interest were a GREEN HERON, WILLOW FLYCATCHER singing from the 
golf course and a group of CEDAR WAXWINGS in the trees by the parking lot. The 
second OSPREY chick hatched today, the first on Wednesday.

Rose-breasted Grosbeak @ Prospect Park (4/30)   src

"In basic plumage the sexes of Blue-gray Gnatcatcher look alike ... Males acquire a distinct black eyebrow in their prealternate molt, putting them in the minority of North American songbirds that appreciably change their appearance seasonally by molt."    Steve Howell's book on Molt p.205

"[a]dult male Blue Grosbeak apparently attains its breeding aspect not by molt but by the wearing away of cinnamon-brown feather tips that veil the bright waxy-blue undercoat through the winter."    Steve Howell's book on Molt p.233

8. How many eggs do Canada geese usually lay in one nest?
The number of eggs laid by one goose in a nest can range from 1 to 10, but the average for giant Canada geese (Branta canadensis maxima) is between 5 and 6.  The goose lay's one egg per day.  If more than one goose is laying eggs in a nest, as sometimes occurs when geese are nesting close to each other (such as on an island), occasionally 15 or more eggs will be found in a nest.  These nests, which are referred to as "dump nests" because 2 or more hens are laying or "dumping" eggs in them, are seldom incubated by any of the geese that laid eggs in them.  src

Geese start nesting at slightly different dates in different areas; earlier in southern areas and later in northern areas, ranging from March through June with peak activity in April and May in most of the United States. ... Addling means "loss of development."  It commonly refers to any process by which an egg ceases to be viable. Addling can happen naturally when incubation is interrupted for long enough that eggs cool and embryonic development stops. Humans addle where they want to manage bird populations. ... In Canada geese, eggs that are less than 14 days old can be addled humanely. Beyond that time, and when the eggs first begin to float when placed in water, humane treatment of the developing embryo [appropriate humane euthanasia] must be considered.   src

After hatching, there is an amazing change in the attitude of the gander.  Where he would previously chase off any other geese in the area, he now becomes much more tolerant of them.  Indeed, if there are other clutches of goslings in the area, they will often group together in flocks called "creèches" and be looked after by all the adults.  src

The female Tree Swallow is the only female North American passerine that retains her immature plumage into her first breeding season and sometimes into her second. (Stokes & Stokes 1996). Her immature plumage is quite brownish, but may show some blue-green on the back and wings (Turner & Rose 1989).  src

   birds/lizards incl. Bark Anole found on Web   
   World's Smallest Lizard Discovered on a tiny Caribbean island off the coast of the Dominican Republic (2001) - info1 : The newly discovered species not only ranks as the smallest lizard, but it also is the smallest of all 23,000 species of reptiles, birds, and mammals, according to a paper to be published in the December issue of the Caribbean Journal of Science    ... So small it can curl up on a dime or stretch out on a quarter, a typical adult of the species, whose scientific name is " Sphaerodactylus ariasae," is only about 16 millimeters long, or about three quarters of an inch, from the tip of the snout to the base of the tail. It shares the title of "smallest" with another lizard species named Sphaerodactylus parthenopion, discovered in 1965 in the British Virgin Islands. Hedges and Thomas discovered small groups of the new species living in a sink hole and a cave in a partially destroyed forest on the remote island of Beata, which is part of the Jaragua National Park in the Dominican Republic.
   "It is hard to say whether this lizard is as small as a lizard can get, but you would think it probably is approaching that limit because it is the smallest of all 23,000 known species of reptiles, birds, and mammals," Hedges says. "The smaller an animal gets, the larger its surface area gets as a percentage of the volume or mass of its body. At some point, it gets to be physiologically impossible to get any smaller." For the lizard, which lives in a dry environment surrounded by comparatively moist leaf litter, the limiting factor is the danger of desiccation. "If we don't provide a moist environment when we collect them, they rapidly shrivel right up and die by evaporation from the proportionally large area of their surface," 
 World's smallest frog has been discovered in Papua New Guinea (2012) - info1 :

   At 7mm (0.27 inches) long, Paedophryne amauensis may be the world's smallest vertebrate - the group that includes mammals, fish, birds and amphibians.  The researchers also found a slightly larger relative, Paedophryne swiftorum.  Presenting the new species in PLoS One journal , they suggest the frogs' tiny scale is linked to their habitat, in leaf litter on the forest floor.
   Before the Paedophrynes  were found, the title of "world's smallest frog" was bestowed on the Brazilian gold frog (Brachycephalus didactylus) and its slightly larger Cuban relative, the Monte Iberia Eleuth (Eleutherodactylus iberia). They both measure less than 1cm long.
  
The smallest vertebrates have until now been fish.  Adult Paedocypris progenetica, which dwells in Indonesian swamps and streams, measure 7.9-10.3 mm long. 
   Male anglerfish of the species Photocorynus spiniceps are just over 6mm long. But they spend their lives fused to the much larger (50mm long) females, so whether they should count in this contest would be disputed. 
   Paedophryne amauensis
 adults average 7.7mm, which is why its discoverers believe it how holds the crown.

From: "Joseph O'Sullivan" <josullivan58 AT gmail.com>
Date: Wed, 9 Mar 2011 17:09:00 -0500

I did not see a northern goshawk at Jamaica Bay National Wildlife
Refuge in the two hours I was there today.

It was still a very good day at JBNWR, including a common raven south
of the west pond. The raven was picking at something on the gravel
trail south of west pond about halfway between the visitors center and
the terrapin trail for a few minutes then took off and flew east
towards the visitors center.

There were 1000+ snow geese in the marshes west of the west pond, and
ebird also lists this as an unusual sighting.

Other noteworthy sightings were a first of the season for me and a
sign of coming spring, a gray catbird.

"Unlike most North American ducks, the adult male Ruddy Duck molts into a bright alternate plumage in late winter and then back into a dull basic plumage in fall, after breeding."   Steve Howell's book on Molt p.73
"Basically, molt is all about food, which in turn is related to climate.  Where different populations live and migrate can influence both the timing and extent of molts.  For example, locally breeding male Ruddy Ducks ... in coastal central California usually molt into alternate plumage in January or February; in the same area, most wintering birds from other populations retain basic plumage through March or April, when they leave for northern and interior breeding areas where spring comes later."   Steve Howell's book on Molt p.48
At West Pond, birders saw on March 1 afternoon/dusk: Tree Swallow - 1, "Eurasian" Green-winged Teal - 1 male, Short-eared Owl - 1 hunting over the phragmites around the entire pond, American Pipit - 1 flying around, American Woodcock - 3+ (heard only), Common Merganser - 1 male, Ring-necked Duck - 11+ (10+ males, 1 female).  They did NOT see the Barrow's Goldeneye on the West Pond at dusk, and there were only ~85 Common Goldeneye. However, Corey had seen the Barrow's Goldeneye on the pond briefly this morning and it was with ~150 Common Goldeneye.  src

Took the best pictures of Starling so far.   <1>   <2>   <3>   <4>   <5>   <6>

This (probably male) Starling is looking forward for breeding: less speckled, iridescent green and yellow-orange with a blue-grey base bill.

WWear Related Plumage Change:  The white tips of the feathers that we see as spots (in winter) become worn and gradually disappear, so that the bird can change its plumage/aspect from one season to the next without molting which is very costly.

Moulting occurs once a year, in late summer after the breeding season is finished; the fresh feathers are prominently tipped white (breast feathers) or buff (wing and back feathers).

Its molting strategy is complex basic (House Sparrow too), typical of temperate-zone songbirds that are residence and short-distance migrants.  Prebasic and preformative molts occur mainly on or near the breeding grounds, between the end of breeding season and the onset of winter.

Photo found on the book:  first-cycle Starling in molt

Nuthatches, Black-capped Chickadees, Woodpeckers, first-year male Red-winged Blackbird, Mourning Dove, Cardinal, Blue Jays (heard), saw hawk flying over high in the sky two times.

In a brief stop at Ft Tilden, in Queens/Brooklyn, I saw 2 Red-shouldered Hawks, one adult and one juvenile. The juvenile at least has been seen in the area within the last week so the birds may be hanging around there. I also saw the adult perched off Flatbush Avenue opposite Floyd Bennett Field as I was driving out making it, at least, a true Brooklyn bird.

Also of note at Ft Tilden, and also seen by Eddie Davis, was the continuing male Harlequin Duck near the fisherman's parking lot. Additionally, a large flock of Snow Buntings was working the island.

NYC Audubon Trip - Snowbirds of Floyd Bennett Field & Fort Tilden, Queens

Sunday, February 6, 10:30am-4pm
Guide: Gabriel Willow

Winter brings many rare birds to NYC that can't be found here at any other time! Perhaps most exciting are the "snow birds" of the Arctic tundra that can occasionally be found in tundra-like habitats further south, such as snow buntings and snowy owls. We will travel to Floyd Bennett Field in search of these and other winter visitors (such as horned lark, tree sparrow, and rough-legged hawk). We will then head to Fort Tilden and Breezy Point to look for wintering ducks, grebes, loons, and other seabirds. Transport by passenger van included. Limited to 12. $75.

Snowstorm Shatters New York City, Philadelphia Records (January 27, 2011; 9:00 AM)
The recent storm total snowfall in New York City was 19.0 inches. The 12.3 inches that fell alone on Wednesday broke the day's long-standing snowfall record of 9 inches from 1871. 總降雪量(19in), 單日降雪量(12.3in).
The storm also pushed the month's snow total to 36.0 inches in New York City. That makes this January the snowiest on record, bypassing January 1925 and its 27.4 inches.
This January is also now New York City's second all-time snowiest month, falling short to February 2010 and its 36.9 inches.

如果海鷗離開水面,高高飛翔,成群結隊地從大海遠處飛向海邊,或者成群的海鷗聚集在沙灘上或岩石縫裏,則預示著暴風雨即將來臨。

海鷗之所以能預見暴風雨,是因為海鷗的骨骼是空心管狀的,沒有骨髓而充滿空氣。這不僅便於飛行,又很像氣壓錶,能及時地預知天氣變化。此外,海鷗翅膀上的一根根空心羽管,也像一個個小型氣壓錶,能靈敏地感覺氣壓的變化。   src: http://tw.myblog.yahoo.com/frank-blog/article?mid=6875&prev=6876&next=6848

鸥一般是泛指鸥形目,鸥科的95种鸟类。但并不存在 "河鸥" 和 "海鸥" 的区别,因为大多数鸥都能在海洋或河流中生存,主要取决于食物和气候,但一些远洋鸥类,有时也会因为迷失方向而进入内陆河流。 例如渔鸥,它们主要繁殖于青藏高原的咸水湖中,但冬季迁徙至孟加拉湾沿海越冬;黑尾鸥在中国东部的沿海岛屿上繁殖,但冬季也常进入内陆河流觅食鱼类;红嘴鸥繁殖于中国东北及西伯利亚地区的淡水湿地中,但在沿海和内陆湿地均可越冬,主要取决于食物量的丰富程度;还有一些鸥,如银鸥和大黑背鸥,它们甚至可以不依赖水域生存,银鸥可以进入草原捕食鼠类和蝗虫,大黑背鸥则可在北极地区捕食其它水鸟,如三趾鸥、海雀、鹬的成鸟和幼鸟,以及野兔和旅鼠。 src: http://zhidao.baidu.com/question/128236036

Subject: Montauk: Black Vulture, impressive scoter numbers+
From: Benjamin Van Doren <nimajneb3 AT gmail.com>
Date: Tue, 28 Dec 2010 20:37:42 -0500
Hi all,

Anne Swaim, Larry Trachtenberg and I birded Montauk for a few hours
today. At about noon, we saw a lone BLACK VULTURE fly low over the Montauk
Point SP parking lot.

I haven't spent much time seawatching at Montauk Point, but it seemed that
there was a very large number of scoters and eiders flying with the wind
past the point today. We estimated perhaps 50 birds per second on average,
and the stream was going strong both when we arrived and when we left two
hours later. If you do the math, that's 360,000 birds in just that two hour
period, and the species composition was roughly 50% Black Scoter, 20%
White-winged, 20% Surf, and 10% Common Eider. I've posted a short video that
I digiscoped with my phone (http://flic.kr/p/95sWsF), but it doesn't do the
spectacle much justice. Is this a typical occurrence for Montauk, or perhaps
related to the recent storm?

Also of note, a few RAZORBILLS could be seen flying with all the scoters. A
group of about a dozen AMERICAN PIPITS were hanging around the point too.

Good birding,

Benjamin Van Doren

"Giant tortoises are among the world's longest-living animals, with an average lifespan of 100 years or more.  The Madagascar radiated tortoise Tu'i Malila was 188 at death in Tonga in 1965.  Harriet was reported by the Australia Zoo to be 176 years old when she died in 2006. Also, on 23 March 2006, an Aldabra Giant Tortoise named Adwaita died at Alipore Zoological Gardens in Kolkata. He was brought to the zoo in the 1870s from the estate of Lord Robert Clive and is thought to have been around 255 years old when he died."  wiki
    Mammal:  Fin whale (116, 114), Blue whale (110), other whales (100, 95, 90, 77, 77, ...)   src
Brain Size Associated With Longevity in Mammals :
    Mammals with larger brains in relation to body size tend to live longer. ... The brain size of some mammals is larger than expected for their body size. This is the case of large primates, such as chimpanzees and gorilla, and of whales, dolphins and elephants.
    Researchers analysed a series of other variables which could be related to higher longevity, such as metabolic rates -- the amount of energy expended while at rest -- diet or habitat, and concluded that none of these can be significantly associated with longevity. Connections are made however not only with a larger brain size, but also with a larger body size, given that large animals are known to live longer. Nevertheless, the Centre for Ecological Research and Forestry Applications (CREAF) researchers confirm that the size of the brain affects lifespan regardless of the size of the body. Hyenas, for example, have a larger brain than giraffes in proportion to body size and on average live longer, although they are smaller than these herbivores.   src
It may also be true in birds to certain extent?
It is interesting that there seems to have been no change in the life span of dogs, cats, horses and cows under thousands of years of domestication by man.  src: from a 1973 bulletin
    Invertebrate :  Lobster (100)
Knowledge of body size at age makes scientists believe that lobsters can attain a maximum age of 100 years. The normal life span is about 15 years. Lobsters can grow to be 3 feet long in overall body length. src
I read news that an 18-pound lobster of more than 70 years old will move to NY Aquarium. Google 'lobster of more than 70 years old will move to NY Aquarium': http://www.zagat.com/buzz/los-angeles?page=1 The 75-year-old lobster is now living the good life at the New York Aquarium on Coney Island, where he's pleasing eyes rather than taste buds.
Google 'the oldest lobster'
Lobsters may exhibit negligible senescence and some scientists have claimed that they could effectively live indefinitely, barring injury, disease, capture, etc.  src

Maximum observed life spans of some organisms thought to be negligibly senescent:

  • Rougheye rockfish (Sebastes aleutianus)—205 years
  • Aldabra Giant Tortoise—255 years
  • Lobsters are believed to live 100 or more years.  But "exact ages cannot be determined because lobster shed all hard parts when they molt, leaving no evidence of age. Scientists have estimated that the American lobster may live to be 100 years old, but it is more likely that the maximum age is 50 years."   src (National Oceanic and Atmospheric Administration)
  • Sea anemones generally only live up to 60–80 years
  • In recent times, the Russian malacologist Valeriy Zyuganov received worldwide reputation after he determined the maximum lifespan (210–250 years) in the freshwater pearl mussel (Margaritifera margaritifera). The data of V.V. Zyuganov have been confirmed by Finnish malacologists and gained general acceptance.

What animal can count?

 

List (with the max. they can count)

-----------------------------------

Social insects - honey bees (4)

Mammals - dolphins (?) or monkeys (4 for chimps)

Birds - Crows (9 or higher, 16?), pigeons (9), Cormorants (8), parrots (6), European Robins (12?) and probably more (Many birds are also able to detect changes in the number of eggs in their nest.)

 

 

Note:

European Robins have some innate ability to discern between small numbers as three and four and through trial and error, they can train themselves to identify numbers up to 12.

Crows show tool-making and tool-using behavior.  Crows and Ravens can talk with each other, count to 9 (compared with 4 for chimps), and steal. They play—sliding down long snow banks, for example. The birds covered about 10ft each time and returned on a second day for more fun and games. Crows are the most social and intelligent species of all birds. Crows mate for life and the young stay with the family unit for up to five years and help the parents raise siblings.

Many animals can tell a larger quantity from a smaller quantity. For instance, many animals can pick a pile with six pieces of food instead of a pile with five pieces of food.  Children who have not learned how to count yet, can do the same thing. But being able to notice differences in quantity is not the same thing as counting. Scientists now believe that certain birds and animals can actually count. In one experiment, a pigeon was offered one grain at a time. All the grains were good to eat, but the seventh grain was always stuck to the dish. After a while, the pigeon learned to count to six grains, and when the seventh grain was offered it refused to peck at it. This was real counting! In another experiment, a chimpanzee was taught to pick up one, two, three, four, or five straws and hand over the exact number of straws that was asked for. But this was as far as this chimpanzee could count. It always made mistakes above five.
