Distribution

South America breeds in Tierra del Fuego, southern Argentina, and extreme southern Chile. It winters north to the Valdés Peninsula, sometimes as far as Buenos Aires Province in Argentina.

Taxonomy

Not actually a plover; this species is the sole member of its own family the Pluvianellidae. It is a monotypic species[1].

Habitat

Edges of brackish lakes and lagoons, ponds, estuaries and coastal areas.

Behaviour

Actions

Pecks food from surface turning over small stones, seaweeds, shells and debris with its strong bill to find food. It also uses its legs and feet to scratch or dig into the sand for hidden prey, a behaviour unique among waders.

Diet

Shrimp, sandhoppers (amphipod crustacean of sandy shores) and tiny arthropods.

Breeding

They use a hollow in the ground to lay 2 eggs, which are grey with dusky spots, which have all the appearance of stones. Both adults incubate the eggs and care for the young. Adults secrete a crop milk not unlike that of doves to feed their young.

Vocalisations

Most common call is a ringing coo or ceu sounding like a cross between a dove and a plover. Also an ascending whistle weeEEEEooooo. Alarm call is a pip-wheet.

Movements

Resident, dispersive and migratory. After the breeding season they move to the coast north to the Valdés Peninsula and occasionally to southwest Buenos Aires Province. Argentina and Falkland Islands.
