Habitat Requirements
Barren to sparsely vegetated sand beaches, dry salt flats in lagoons, dredge spoils deposited on beach or dune habitat, levees and flats at salt-evaporation ponds, river bars, along alkaline or saline lakes, reservoirs, and ponds. Nests are a natural or scraped depression on dry ground usually lined with pebbles, shell fragments, fish bones, mud chips, vegetation fragments, or invertebrate skeletons.
Food Habits
Terrestrial and aquatic invertebrates are their main food items. Walking and hopping are employed in feeding, as well as several other activities.
Movement / Home Range
The Snowy Plover breeds along the Pacific coast of the U.S., with this range also covering several southwestern states, while wintering along the coasts of the Baja Peninsula, western Mexico, the Gulf of Mexico and Guatemala. Distances of migratory movements are relatively short, with the direction of movement to winter areas being either northward or southward for the Pacific coast breeders, but northeast or southwest for birds breeding in the interior of western North America.
Other
Habitat alteration and increased use of recreational beaches threaten the conservation of this species. Also at risk from sea level rise and stochastic events such as oil spills. The breeding population has likely decreased on the Gulf Coast since late 1800s. This species is on the 2014 State of the Birds Red Watch List, which lists species most in danger of extinction without significant conservation action.
