- Were we spoiled by November’s unseasonably warm weather in South Jersey — with so many daily temperatures of 60+? We recorded 23 species for the month: black swallowtail, spicebush swallowtail, cabbage white, clouded sulphur, orange sulphur, cloudless sulphur, eastern tailed-blue, gray hairstreak, American copper, pearl crescent, variegated fritillary, question mark, eastern comma, mourning cloak, American lady, painted lady, common buckeye, red admiral, monarch, common checkered skipper, fiery skipper, sachem, and Ocola skipper.
... Over our seven years of logging, 2008-2014, we have recorded fourteen species flying in December, although none has made it every year. In fact, in 2010 winter freeze set in early and we did not log a single butterfly of any species that December. ... Orange sulphur seems the most reliable late flyer — with December records for all years except 2010 and a latest-ever date of 12-31-11. The next-most reliable species are common buckeye, red admiral, American lady, and monarch which have each appeared in five of our seven Decembers. ...

... did you ever notice that a bathing Mallard always ends by sitting up in the
water, flapping its wings, bending forward, and shaking its tail in the air,
often dipping its bill into the water? ...
Displays like this are often used to communicate with other birds.
Mallards have a huge variety of displays that can be fascinating to watch and
decipher. Most displays are ritualized versions of common motions: males may
face off with a head-bob, threaten an aggressor with an open bill, or push
against each other, breast to breast. Paired males defend their territories with
vigorous acrobatic chases. Males court females by shaking or flicking the head
side to side, looking over their shoulder, or raising up in the water and
flapping their wings. Several males often gather around a female to display. A
female encourages a male by nodding her head back and forth or paddling with her
head held low. src

seen diving for food. They appeared to be eating salmon eggs - which are not
usually part of their traditional diet. Following is the relevant article: Mystery

(8) Dragonfly Swarms, Wisconsin (2010) By
The BugLady: It’s been a remarkable year for
dragonflies in southeastern Wisconsin. They made the print and television news
in early August, when green darners, appearing in huge swarms ...
Some of our green darners migrate here, ushering in the dragonfly season during
the early days of spring. These migrants, nearing the end of their journey both
geographically and cosmically, lay eggs in the warming waters and soon die.
Their eggs hatch into young called naiads (稚蟲 , i.e., 蜻蜓 若蟲), which spend the summer under water,
preying on their fellow aquatic invertebrates (including quantities of equally
aquatic mosquito larvae). The naiads emerge as adults in late summer and migrate
south in fall, and their offspring will make the return journey to Wisconsin the
Another population of green darners is home-grown, and their watches are not
synchronized with those of the migrants. Naiads of the resident green darners
spend the winter under the ice, feeding in slow motion on small critters in the
frigid water. They emerge in early summer, replacing the dying adults of the
migrating population, and they lay their eggs by mid summer.
Unusually large summer dragonfly swarms were not unique to Wisconsin on 2010.
The phenomenon was reported from Iowa to Vermont to Florida, and points in
between, with green darners a major player in most accounts and with local
experts offering a variety of explanations and assuring their audiences that
dragonflies are harmless to people, pets and livestock. In general, weather gets
the credit for producing huge numbers of insects. There was an early, deep,
insulating snowfall here before the wetlands froze, which was favorable for the
naiads and their prey. There was an early spring – it got warm and it stayed
warm, favoring abundant food for growing naiads. July was hot and wet, and the
rain filled low lying areas, creating impromptu, fish-free nurseries for aquatic
insects. The adult dragonflies emerged a bit early, simultaneously with an
explosion of dragonfly food.
So, what were all those dragonflies doing up there? An aquatic entomologist who
blogs under the name of “ Dragonfly Woman ” is collecting reports of dragonfly
swarms (she invites people to send their observations to her website at http://dragonflywoman.wordpress.com/).
She writes that where last year she was getting 30 hits per week on her swarm
pages, this year she is getting 500 hits. Dragonfly Woman divides swarming
behavior into low-altitude, static (mostly feeding) swarms and high-altitude
migratory swarms. Static swarms tend to be localized, with groups of dragonflies
of several species circling or flying in figure-eights, no higher than about 20
feet off the ground. Static swarms happen in mid-summer. If you look closely,
you might see their small prey just above the grass-tops. If there are lots of
small static swarms, they may be part of a larger super-swarm.
Dragonfly Woman describes migratory swarms as fast-moving "rivers of hundreds of
thousands of dragonflies all flying in a single direction and covering large
distances." There may be several species present, but one species dominates.
Only about a dozen of the 400 or so dragonfly species in North America migrate;
the rest live and die near their natal wetlands. The same species that form
migratory swarms are found in static swarms.
Scientists who study dragonfly migration find that dragonflies and birds are on
the same page. Tiny tracking devices that were glued to the abdomens of green
darners allowed the dragonflies to be tracked by air. It was discovered that
like birds, dragonflies use weather fronts to initiate migration and will take
advantage of a tail wind associated with a cold front (but both avoid really
windy days). Both will alternate flying and resting days, and both follow visual
landmarks. The cool weather in the first week of September got both the
dragonflies and monarch butterflies started.
(9) So look like Green Darner adults which migrate to south in the onset of
winter do not live through the winter in their wintering grounds like Monarch.
They lay eggs in the wintering ground and die.
What you’re seeing is a flocking behavior called “staging,” which happens in
bird migration. Flocking offers birds protection from predators, and sitting
close together, or staging, does, too. While they might not be actively
migrating at the time you see them, their instinctually exhibit migratory
It is quite likely the swarming birds you’re seeing are European Starlings
at this time of year. Or, they could be grackles or a mix of species, such
as European Starlings, grackles, and Brown-headed Cowbirds.
(11) I saw hundreds of birds land on a telephone line and it seemed all were
facing in the same direction. Is anyone aware of a reason why?
Scientists believe the main reason that birds face the same way on a wire is due
to the direction of the wind. Birds have an easier time taking off and landing
facing the wind.

Note about Robin:
do robins prepare for winter?
October they start seriously adding down feathers to improve their insulation
for winter. Also, summer food supplies have diminished; there are still plenty
of berries around to eat, but robins get seriously on the move in search of
plentiful food supplies for the coming winter. They start seriously moving in
October. Back on October 1, 1988, birdwatchers counted over 60,000 robins
migrating over Duluth in northern Minnesota, so that's serious migration. But in
fall and winter, robins don't stay in a single spot for long — they wander about
searching for new sources of still-fresh fruits.
do robins molt just before they are about to migrate south?
molt so they will have fresh feathers for their flight. These fresh feathers
will also be very good for insulating them from the winter cold. Robins start
molting their flight feathers in mid-June, and have finished molting them by
early September. They molt their body feathers from late July into October. One
by one, each feather is pushed out by a new one. Most feathers last for a whole
year. If a feather gets pulled out when the robin isn't molting, that feather
gets replaced fairly quickly.

(1) Bullfrog Tadpoles -
Bullfrog tadpoles, known scientifically as Rane
are native to eastern North America and can be found as far north as Canada and
as far south as Florida.
Tadpoles are as easy to spot as their much larger parents. While much larger
than tadpoles of other frog species (they range up to a sizable 15 centimeters
in length), they tend to sport the very same coloration of their parents – skin
that is very dark green, almost black to the human eye.
The Bullfrog tadpole’s appearance is distinct and one of the reasons why it is
easy to spot (its color is another reason). The tadpole has an arrowhead-shaped
body with a dorsal fin that actually begins behind its body. And while it is
small in size compared to adult Bullfrogs, the Bullfrog tadpole is actually
quite large compared to adult frogs of other species.
Additionally, Bullfrog tadpoles mature much more slowly than tadpoles of other
species. While the tadpoles of competing species may complete metamorphosis in
as little as just a few short months, Bullfrog tadpoles can remain in the same
state for as long as one to two years before they actually become adult frogs.

(11) Bee Mimics:
are one of the most common bee mimics in Illinois, and often very well
disguised. Even so, there are two simple ways to tell a fly mimic from a bee.
First, look at the wings: bees have four
but flies have two
Second, look at the antennae: bees have elbowed antennae,
while many flies have short, stubby, or hair-thin antennae. If you can't see the
antennae, you're probably looking at a fly.
flies, or hover
flies, look and sound very similar to bees. When flying, their wings and
antennae can be very difficult to observe - but their behavior will be very
different from a bee. These flies hover and move erratically; bees generally
move slowly from flower to flower, and do not hover in one place.
(12) Mimicry in hoverflies (Diptera: Syrphidae): a field test of the competitive
mimicry hypothesis -
Although most studies on the evolution of mimicry and warning coloration in
insects have considered predators as the major selective force, it is possible
that competition for food resources could also facilitate selection for these
conspicuous signals. For example, when warningly colored social wasps visit
flowers, then they frequently behave aggressively toward heterospecifics, and
they also attack and feed on other flying insects. Under these conditions, a
resemblance to a wasp might provide a mimetic hoverfly with improved access to
floral resources by reducing the frequency with which it is disturbed by other
pollinators. We experimentally evaluated whether wasp-like colors and patterns
were important in preventing other flower visitors from sharing the same flower
resource, using pairwise presentations of both natural and artificial prey in
the field. Flower visitors were more likely to visit unoccupied flowers compared
with the flowers pinned with either natural or artificial specimens in 2 plant
species with different inflorescences. However, flower visitors did not show a
significantly reduced rate of visitation to flowers pinned with specimens
bearing wasp-like colors and patterns compared with the flowers occupied by
similar-sized specimens that were nonmimetic. Overall, we found no compelling
evidence in this study to support the contention that wasp-like warning signals
of hoverflies prevent other flower visitors from sharing flower resources,
although insects showed a greater tendency to avoid visiting flowers pinned with
a wasp compared with flowers pinned with a nonmimetic fly.
(13) Picture found on Web:
Wasp mimicking hoverfly (Conopidae)
- Physocephala tibialis
mimicking the constricted waist that is supposedly one of the diagnostic
characters of Hymenoptera (wasp-waist).
Two kinds of bee mimics
a. syrphid/flower/hover fly: they eat nectar and/or pollen; pollinators;
they do not bite or sting, although they may land on you because they like the
taste of your sweat. Some people mistakenly call these little flies "Sweat bees", which is actually a family of bees (Halictidae). *Remember: flower fly is not sweat bee.
Bombyliid flies too. They have exceptionally long
proboscises, which they use for probing flowers for nectar. They are fairly adorable, as far as flies go; essentially they are little round fuzzy balls. Maybe, just maybe, they are my
favorite representative of that sometimes despicable (read: mosquitoes) order of Diptera.
More on wiki.
b. mimics bees for a different purpose: to eat them! By perfectly imitating a bee, a predator can sneak up on a bee. The Asilid
(Robber flies) family of flies is one example.

Ornate Sniper Fly (Chrysopilus ornatus)? Does this species in particular specialize on bees?
This species of the family Rhagionidae is found over most of the northeastern U.S. and adjacent southern Canada.
There are several different forms of plumage abnormality centred on altered
amounts of pigment. These include leucism
and albinism (where
there is loss of the pigment melanin), melanism (in which the amount and/or
distribution of dark-coloured melanin pigment is often elevated), erythrism
(where a chestnut-red pigment replaces certain other pigments) and flavism
(where there is an excess of yellow pigment). Both erythrism and flavism are
thought to be rare compared with leucism and melanism.

(1) Peregrine Falcons: Too Much of a Comeback?
Now [i.e., 2010], according to the New
York State Department of Environmental Conservation, which still lists
peregrines as endangered in New York State, New York City “has probably the
largest urban population of peregrine falcons anywhere, and peregrines nest on
every Hudson River bridge south of Albany.”
Of course, Peregrine Falcons are awesome birds and it is certainly better that
they exist and persist in the eastern United States then the alternative, but I
have to wonder what the presence of year-round Peregrine Falcons is doing to the
populations of shorebirds, puddle ducks, and other species that make their way
through New York City on migration each year. A recent visit to Jamaica Bay’s
East Pond gave me an inkling. ...
As the tide came in and filled the Jamaica Bay basin more and more shorebirds
came in to roost at the East Pond, as they do at every high tide. Roosting
conserves energy when the birds can’t actively feed, and helps them to fatten up
for the next stage of their long migration. It also gives birders like a me a
chance to search through the flocks hoping to find rarities. But the shorebirds
get no rest and the birders get no chance to sift through the thousands of birds
when a Peregrine Falcon is hunting in the area.

Just got off the phone with FWS law enforcement. Since kinkajous
are not a protected species, and are commonly bred in the US it was most likely
not smuggled in. She agrees that it most likely became too much for someone and
they just dumped it. - See more at:
