Wilson’s Plover
Wilson's Plover
Anarhynchus wilsonia
At a Glance
Several of our plovers are small birds with single dark neck rings. Wilson's Plover is slightly larger than the others, and has a more southerly distribution, living on beaches along the southern Atlantic and Gulf Coasts. Its oversized bill is not only its best field mark, but also a clue to its feeding behavior: some studies have shown that it tends to capture and eat slightly larger creatures than the other plovers on the beach.

Behavior
Eggs
3, sometimes 2, rarely 4. Buff, blotched with brown and black. Incubation is by both parents, 23-25 days. Male usually incubates at night, female most of the day.
Young
Downy young leave nest soon after hatching. Both parents tend young, but young feed themselves. Age at first flight roughly 21 days.
Feeding Behavior
Typically they run a few steps and then pause, then run again, pecking at the ground whenever they spot something edible.

Many crustaceans, also worms, insects. Crustaceans in diet include many crabs, such as fiddler crabs and others, also crayfish, shrimp. Also eats small mollusks, marine worms, many insects and their larvae.
Nesting
Nests as isolated pairs or in loose colonies. In courtship, male goes through ritualized nest-scrape making; male postures near female with wings drooped, tail held low and spread, pattering with feet. Nest site is on dry part of beach, often near piece of driftwood, clump of grass, or other conspicuous object. Nest is simple scrape in sand or shell of beach, usually with sparse lining of pebbles, pieces of shell, grass, debris. Male makes several scrapes, female chooses one.
