The Canadian Wildlife Service has just released its "Estimates of
shorebird
populations in North America" (Occasional Paper Number 104) authored by
R.I.G. (Guy) Morrison (2001) and five other Canadian and American
ornithologists. Remember that these numbers are best estimates. NA =
North
America.
1. Black-bellied Plover: Global 498,000 with 200,000 in NA.
2. American Golden-Plover: 150,000+
3. Pacific Golden-Plover: Global population 125,000 with 16,000 in NA.
4. Snowy Plover: Global 586,000 with 16,000 in NA.
5. Wilson's Plover: 6000+
6. Common Ringed Plover: Global 442,500 with less than 10,000? in NA.

my
opinion, the Eskimo Curlew has been extinct for many years. Last
specimen
taken in Canada on 29 August 1932 in Labrador. Last photographed (one)
in
March and April 1962 near Galveston, Texas. Last specimen shot on 4
September 1963 in Barbados, West Indes. No 100% reliable sightings since
the 1960s. Recent reports probably are juvenile Whimbrels with short
