Appearance:

White forehead with white wedge above eye in all plumages. Legs, and most of bill yellow in adult breeding plumage. Very small and longwinged tern. Only 2/3 of size of Common Tern. Head and bill proportionally longer than Chlidonias species and congeners, while tail is shorter. Back paler grey and belly whiter. First primaries form a dark front edge to wing. In winter the bill darkens, legs turn a dirty yellow and the white forehead expands. Juvenile resembles adult winter, but has yellowish bill base and scale patterned back. Flight fluttering with rapid wing-beats, which together with size, is usually sufficient to determine the species.

Sound:

Fairly distinct voice. Contact call a sharp "kitt", often combined to form undulating, rolling series. Not as sharp and penetrating as Common- and Arctic Tern.

Appearance:

Large, long-tailed eagle. Juveniles unmistakable, with white base of tail, dark terminal band and base of flight-feathers forming a white wing panel. Adult: dark brown with golden tinge to head. Variable amount of white wing panels and base of tail in intermediate plumages. Differs from other eagles by; wings held in shallow V when soaring, narrow wing base, flight feathers paler than coverts and body. Flight pattern elegant with a handful deep beats and typical alternate glides.

Sound:

Not very vocal. A short, clear, yelping "kew". Sometimes in series in mellow tempo. Also mewing, Buzzard-like calls.
