LIFE HISTORY

ORIGIN: native *404*; REPRODUCTION: 3 eggs (usually)/once a season *432*; with time span in Virginia of May 7-June 30 *700*; 24-25 day incubation *432*; by both sexes *507*; BEHAVIOR: nests in broadly dispersed colonies; nest site is a scrape or hollow in sand or shell; some nests are out in the open, others next to some object or shaded by beach grass *432*; both parents care for young *432*; this species seldom mixes with other species, preferring solitary, uninhabited spots for foraging *432*; it feeds at or near the tide line *696*; species is migratory *404*; POPULATION PARAMETERS: this species suffered in Virginia from the hunting practices of the early 1900's *696*; the population is suffering again due to loss of nesting habitat as development restricts this species to the barrier islands *696*; Wilson's plover was cited in the blue list for 1980 in the marginal category, suggesting special attention be given to determine status *411*; AQUATIC/TERRESTRIAL ASSOCIATIONS: nesting nearby: willets; least terns; oystercatchers *432*; some nests are shaded by grass blades or other vegetation *432* REFERENCES FOR LIFE HISTORY- 696, 432, 404 and 411 Life History - 1
