Mute Swan (Cygnus olor)
Gannet (Morus bassanus)
Big and white waterfowl with orange bill and black knob at base of bill. Juveniles more greyish and differs from juvenile Whoopers by all grey bill and black lores. Neck usually held more S-shaped than other swans when swimming. Long tail prominent when upending.
Sound:Silent compared to other swans. A repertoire of snorting, grunting and hissing sound when interacting. No far carrying sounds. Wings produce prominent singing sound which may function as a flight contact-call.

CCWhite with black wing tips and yellow-buff at back of head. Juveniles brown with small pale speckles, white u-shaped rump patch and pale underparts. Fully coloured only after 5 years, and patchy, intermediate plumages often seen. Unmistakable bird at close range or with favorable light, but can be confused with shearwaters at a distance and/or in strong wind. Differs from those by long tail and much longer neck and head. Alternates between powerful, even and shallow wing-beats and glides. Flight becomes more shearwater-like in strong winds.
Sound:Heard mostly at breeding ground. Even, rhythmical series of harsh "harrr, harrr, harrr,".
