Piping Plover
-------------
1.
      The approximate global population of Piping Plovers consists of
some 6,000 adults, of which approximately 2,000 are found along the
coastline of Atlantic Canada. (I think it is based on 2001 International
Piping Plover Census)

2.
       In 2001, the total population of
Piping Plovers in North America was
estimated to be 5,945 breeding
adults. The Texas Gulf Coast had the
highest wintering population, with
about 1,042 individuals detected.
This represents about 44% of birds
detected on the wintering grounds
during the 2001 International Piping
Plover Census.

2006 International Piping Plover Census
A grand total 3,884 Piping Plovers were recorded during the winter
census. Birds were observed at 546 sites (table 1). Expanded coverage
outside the United States led to the discovery of a large population of
Piping Plovers in the Bahamas (417 birds or 10.7 percent of the winter
total). A grand total of 8,092 adult Piping Plovers were recorded during
the breeding census at 1,925 sites (table 2). Site-specific information
is provided for each survey (appendix 1).
