Goldfinch (Carduelis carduelis)
Common Tern (Sterna hirundo)
Plumage stunningly colourful. Adults easily recognized by red face boldly framed in black and white. In all plumages; black wings with broad yellow panels, forked tail with white patches, and flashing white rump. Bill fairly long and pointed. Juveniles lack the red, black and white head, and are best identified by the contrasting wing-panel and white rump/tail patches. Light and bouncing flight, with bursts of wing-beats and variable acceleration.
Sound:Contact-call distinct, and also constitutes a major part of the song. A sharp and explosive "witt", or "tzee-witt". Sometimes given as a single syllable, di- or trisyllabic, or as continuous series. The song is comprised of rapid series of the contact call, interrupted by drawn-out melodic notes and trills. Other calls: A harsh budgerigar or house martin-like "trrrtt-trrrrt".

CCSounds:Recorded by Edmunds Racinskis
Differs from Arctic Tern in longer head, and more orangy red, rather than deep red, bill. Tip of bill usually black. Legs longer, but tail streamers shorter than AT. Underparts of primaries with diffusely bordered dark trailing edge (sharply bordered in Arctic Tern). Upper side of primaries with dark wedge (less apparent in winter). Secondaries opaque. Crest more apparent than in Arctic Tern and underside whiter. Juveniles with buff back.
Sound:Similar to Arctic Tern but deeper. Lacks latter's high pitched "tip-tip-tip" call, and the drawn out "kree-aaahh" call falls more distinctly in pitch.
