Whimbrel
Whimbrel
Numenius phaeopus
At a Glance
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.

Behavior
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.
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.
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.
Conservation
Conservation Status
Numbers were seriously depleted by market hunters in late 19th century, have recovered somewhat since.
