Black-tailed Godwit (Limosa limosa)
Marsh Harrier (Circus aeruginosus)
Most likely to be confused with Bar-tailed Godwit, but easily recognized in flight by its contrasting black and white wings and tail. More difficult to identify when not flying. Generally much leggier, more elegant and upright than Bar-tailed, and with straighter bill. Tibia especially long. Summer plumage with barred/spotted belly (never in Bar-tailed), and orange base of bill. Juveniles with scaled back, not arrow-shaped streaking. Adult winter with mainly uniformly grey plumage, and short supercilium not reaching behind the eye.
Sound:Quite vocal at breeding ground, but mostly silent elsewhere. Varied repertoire of mewing and sharp sounds, some resembling Bar-tailed, some almost lapwing-like. Most characteristic call is the display call; a sharp and mewing, rhythmic "kew-ku-weeewee". Generally the calls are evenly accentuated (as opposed to Bar-tailed).
