Numenius phaeopus

[edit] Identification

Length 37-45 cm (incl. bill 6-9), wingspan 78-88 cm
The body of this bird is patterned in brownish to brownish-grey colours, especially on the underside over a lighter basis. The bill is bent down about 1/3 from the tip. On the side of the head is a dark stripe through the eye, a light supercilium, a dark stripe above that one, and a light central stripe. The three crown stripes are the most conspicous of these if the crown can be seen well.

Three main forms are recognized: the European forms have a light coloured tail and a white rump that continues up the back, but is only visible in flight. Siberian forms have darker tail and lower rump, but still show the white are on the back. American forms have the tail, rump and back of a similar colour to the wings.

[edit] Similar Species

The bill is shorter and less evenly curved than in the Eurasian Curlew. The pattern of stripes on the head and especially in the crown is diagnostic at least in the majority of the range. Bill is significantly shorter than in the Long-billed Curlew.

[edit] Habitat

Breeds on taiga bogs, on mountainsides above tree-limit (e.g. cranberry scrub), and tundra, often with mossy areas. On passage frequents mainly pasture and coasts including tidal mud flats.

[edit] Behaviour

On passage (mostly late April-May and July-August) seen singly or in small parties.

On their breeding grounds, individuals will fly up from hundreds of meters away to confront perceived threats (from Common Ravens to foxes and people). They will harass the intruder with aerial chases and constant calls.

The American subspecies often feeds on small crustaceans, minnows, earthworms, aquatic insets and larvae; also seeds and berries.
