Since they live in lagoons and lake edges, and in winter also in estuaries and coastal zones, it can be very difficult to see it. They walk slowly, pecking and pushing the little stones and algae that finds in their way, and eating the tiny crustaceans of lagoons, lakes or rivers. Its flight is rapid,and broken, being difficult to follow it with sight, and flyng a great distance before descending again.

The first reference of a nest was in November of 1952, nest found to the edge of a lake in Estancia Gente Grande, in the northwest zone of Tierra del Fuego. The nest, a depression on sandy ground, had two eggs that was confused easily with the rounded stones of the sector. In following years were found other nestfuls. The eggs are between smoke gray and pale smoke gray, with numerous dusky spots very fine more concentrated toward the obtuse pole. Average size of 34 x 25 mms. app. Both parents incubate them and care for the nestlings. However, when the food is scarce, the weakest suckling, generally the second, tend to die.

Length: 19½-21½ cm (7¾-8½ in)

  • Grey head, neck, chest and upper parts
  • Whitish throat and cheeks
  • Brown tint on neck and chest
  • White abdomen and under tail coverts
  • Blackish primaries and rectrices
  • Black bill. Pink legs. Red eyes.

Males and females are alike, although the female averages smaller. Juveniles have their upperparts spotted and extensively fringed with white and their breast is slightly streaked with dark grey. Their lores are pale and lack the dark line. Bare parts are duller with the bill showing extensive yellow culmen. Eyes are orange-grey. Legs and feet are more yellowish than on adults.

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.
