Bar-tailed Godwit (Limosa lapponica)
Goosander (Mergus merganser)
Most likely to be confused with Black-tailed Godwit, but easily recognized in flight by plain dark wings, white wedge on back and barred tail. More difficult to identify when not flying. Generally more compact, heavier built and less upright than Black-tailed, and with clearly upcurved bill and shorter legs. Belly always unmarked. Base of bill dark in summer and pinkish in winter and in juveniles. Back with arrow-shaped streaking. Adult winter also streaked, and the pale supercilium reaches behind the eye.
Sound:Quite vocal at breeding ground but mostly silent elsewhere. Varied repertoire of mewing and sharp sounds, some resembling Black-tailed, some almost Snipe-like. Contact call a sharp "kwee-kee-wee-kee", with alternating high and low pitch, and decreasing intensity. Display call a hard and sharp "kuwek-kuwek-kuwek-kuwek", with emphasis on second syllable.

Largest sawbill. Male: white to pinkish white plumage with black back and dark green head. Female with grey body and brown head. Sharp division between brown head and whitish breast, together with contrasting white chin, distinguishes it from female Red-breasted Merganser. Both sexes with hook at tip of bill, dense crest and swollen base of bill. Wing-bars all white. Flight silhouette more diver-like than duck-like.
Sound:Male: Mostly heard when courting. A twanging, disyllabic "whip-ooooo", first syllable ascending and second whistle-like and rapidly falling. Female: A coarse "ahrrr ahrrrr", or a raspy drawn "ah-ahrrrrrr ah-ahrrrrr", slightly rising, then falling in pitch. Also various cackling sounds.
