The Buff-breasted Sandpiper, Tryngites subruficollis, breeds in the open arctic tundra of North America and is a very long-distance migrant, wintering mainly in South America, especially Argentina.
It migrates mainly through central North America and occurs as a regular wanderer to western Europe, where small flocks of them have been recorded in Great Britain or Ireland.
Non-breeding birds are normally found on short-grass habitats such as airfields or golf-courses, rather than near water. They can become very confiding.
The plumage is brown above, with a buff face and under plumage. It has a short bill and yellow legs.
Males and females look alike, except males are generally larger.
Juveniles resemble the adults, but may be paler on the rear underparts.
Nesting / Breeding
The male performs a courtship display during which he raises the wings to show off the white undersides. The Buff-breasted Sandpiper nests on the ground. The average clutch consists of four eggs.
Buff-breasted Sandpipers are believed to hybridize with the White-rumped or Baird’s Sandpipers.
Diet / Feeding
They mostly eat insects and other invertebrates (= animals without internal skeleton, such as larvae, earthworms, millipedes, snails, spiders).
