Appearance:

Unmistakable due to the extremely long, red legs. High contrast plumage with pointed, black wings (both upper and under-side) and white underparts. Tail white, with white wedge extending up back. Back of adult male sooty black, while brownish black in female and immature. Head all white or with black markings independent of sex (males more often have black markings than females though). Immature with faint, pale fringes to coverts, and white trailing edge to secondaries visible in flight.

Sound:

Most vocal at breeding ground. Various short,sharp "kyp" may resemble both Avocet, Coot and Spur-winged Lapwing (Vanellus spinosus). While a tern-like "kee-arr" is more distinct. Note that immature birds have a different contact call closely resembling Wood Sandpiper, but do not utter it in series.

Appearance:

Adults in summer at close range unmistakable. Bill in juveniles almost black, and much less deep than in adults. Adults in winter plumage also show much darker bill and cheeks than in summer. At a distance head gives an all dark impression, with characteristic dark "shadow " in front of the eye. Head and bill less elongated than in other auks. Wings rounded with dark undersides. "Thighs" dark. Flight fluttering and energic, with shifting weight and angle.

Sound:

Deep, but not so coarse as Razorbill. Smoother and more gliding changes in pitch, like a "slow-motion" laugh or distant chainsaw; "aaaahrrr, aahr, ahr arh".
