Black-headed Gull (Chroicocephalus ridibundus)
Tufted Duck (Aythya fuligula)
Chocolate-brown hood in adult plumage (seemingly black at a distance), but head only with dark markings in winter and juvenile plumages. Underparts of inner primaries dark grey. First few primaries white with black tip, both on upper side of wing and under. Last character conspicuous in all plumages, but slightly less obvious in juveniles due to larger dark area of wing-tip. Slender-billed Gull and Bonaparte's Gull show similar white first primaries, but differs in long and slender head profile and white underparts of hand respectively.
Sound:Quite vocal, especially at breeding ground. Distinct, harsh calls. A rasping "kreearr", and shorter, sharp warning calls; "kek".

CCSmall, compact diving duck with short neck and rounded head. Males with diagnostic tuft, white flanks and black back. Females with rudimentary tuft, mostly dark brown body, with varying white feathering at base of bill. Females in winter showing much white at base of bill are easily mistaken for Scaup, but note hint of small tuft, smaller head, broad black nail of bill and no white cheek spots. Both sexes show long, white wing stripes in flight.
Sound:Male display sound: High pitched short whistling-like noises, "pjuu-uu", not very audible. Both sexes have harsh "ahrrrr" calls like other diving ducks, sometimes with a crow-like quality.
