Behaviour

Wilson's plovers hunt fiddler crabs on sandflats and at the edges of marshes, running them down and swallowing them whole or pulling off the legs.

Why they matter

Wilson's plovers nest on open beaches and are sensitive to disturbance. Georgia's barrier islands hold an important share of the breeding population on the Atlantic coast, making the state important to the species' future.

Reproduction and lifecycle

Nest — A scrape in sand near dunes
Eggs — Usually three
Incubation — About 23 to 25 days
Chicks — Leave the nest within hours and feed themselves
Flight — At about three to four weeks
Lifespan — Several years

Living around people

  • Beach nesting areas that are roped off protect eggs and chicks that would otherwise be stepped on.
  • Adults feigning injury are drawing people away from chicks; the kind response is to leave the area.

Misconceptions

  • A chick alone on the sand has been abandoned. Plover chicks feed themselves and hide when danger comes; parents stay close.
