Appearance:

Robust, compact and dark wader, with relatively long and slightly curved bill. Mostly seen in winter at the coast where it prefers rocky surfaces as opposed to most other waders. In winter plumage the base of bill and legs are yellow, and the upperparts grey with dark markings. Breeds in high Arctic and mountains. Summer plumage darker than winter, with brown fringes/spots on back, and darker bill and legs. Similar wing and rump pattern to Dunlin, but appears overall darker. Tail extends beyond wing tips of resting birds. Flight patterns at wintering grounds straight and low.

Sound:

Contact call a hoarse and hard "weet". Sometimes in chattering series. Song quite varied with series of short, nasal, vibrating sounds, interspersed with drawn out, slower calls.

Appearance:

Largest falcon. Heavily built. Grey upperparts and white, speckled underparts. Juveniles with browner plumage than adults, blue-grey legs and longitudinal streaking below. Diffuse moustache-stripe, and the whole head seems dark at distance, lacking a defined cap. Rounder and broader wings, longer tail and bulky belly distinguishes it from Peregrine. Underside of wings with dark coverts in contrast to pale base of flight-feathers. Extremely powerful, but slower flight action than Peregrine.

Sound:

A coarse, drawn out, Peregrine-like "kaaawt", with emphasis on ending, is repeated in series. Much slower paced than in small falcons, and deeper and with different attack than in Peregrine. Also shorter, coarse warning-calls.
