Whimbrel

Numenius phaeopus

The most widespread of the curlews, nesting in the Arctic across North America and Eurasia, wintering on the coasts of six continents. Whimbrels tend to concentrate in flocks at a few favored spots in migration, so that the observer sees either many of them or else very small numbers. The name "Whimbrel," originating in England, apparently began as a loose interpretation of the bird's call.

Conservation status	Numbers were seriously depleted by market hunters in late 19th century, have recovered somewhat since.
Family	Sandpipers
Habitat	Shores, mudflats, marshes, tundra. Found on a wide variety of habitats on migration. Most common on mudflats, but also found on rocky shores, sandy beaches, salt marshes, flooded agricultural fields, grassy fields near coast. In summer, breeds on Arctic tundra.

Feeding Behavior

Forages by walking on open flats, picking up items from surface or probing just below surface; despite long bill, does not seem to probe deeply. When feeding on crabs, may break off legs and crush shell before swallowing body of crab.

Eggs

4, sometimes 3. Olive to buff, blotched with shades of brown. Incubation is by both sexes, roughly 24-28 days. Young: Downy young leave nest soon after hatching. Both parents tend young, but young feed themselves. Adults actively attack predators flying over nesting area, and will fly straight at human intruders, swerving aside at last moment. Age of young at first flight about 5-6 weeks.

Diet

Includes insects, crustaceans, berries. On breeding grounds may feed mostly on insects at first, but berries (such as crowberry and cranberry) become major part of diet by late summer. On coast, often eats many crabs, also amphipods and other crustaceans, marine worms, small mollusks.

Nesting

Early in breeding season, male performs flight display over nesting territory: flies in large circles, alternately fluttering higher and gliding down, while giving whistling and bubbling song. On ground, members of pair may call together. Nest site is on ground, usually in dry raised area near low-lying wet tundra. Nest (probably built mostly by female) is shallow depression, lined with bits of lichen, moss, grass.

Migration

Has a wide wintering range, from our Pacific and southeastern coasts to southern South America. Whimbrels from European and Asian races, with white on lower back and rump, sometimes stray to North America.
