The Snowy Plover is a cosmopolitan species
found not only in North and South America but in Eurasia and
Africa. In North America it is resident on the Pacific Coast
from Washington to Baja California and also at scattered inland
localities, including near the Great Salt Lake, in central
Kansas and Oklahoma south to west Texas and southern New Mexico,
and along the Gulf Coast from Florida into northern Mexico.
There are also populations resident in central Mexico, the
Yucatan, and the Bahamas. During winter the bird withdraws
from much of its inland U.S. range and spends the nonbreeding
season along the Gulf Coast and both coasts of Mexico.
The number of birds in the U.S. is estimated
at 21,000 in 1995, with nearly half the total number breeding
at the Great Salt Lake, but the population along the Pacific
and Gulf coasts of the U.S. is shrinking and its breeding
sites becoming more fragmented due to habitat degradation
and increased recreational use of beaches, and the Pacific
Coast has been designated as Threatened under the Endangered
Species Act. The range of the bird has also shrunk and become
more fragmented along the Gulf Coast of the U.S. Breeding
habitat includes barren to sparsely vegetated beaches, salt
flats, river bars, and sparsely vegetated flats along alkaline
or saline lakes, in addition to reservoirs and sand bars in
rivers. In winter the bird is gregarious and is found in many
of the same habitats and also at agricultural waste-water
ponds. The breeding population has decreased since 1970, particularly
along the Pacific Coast. In some localities along the West
Coast nesting beaches are posted to protect the bird.
