Appearance:

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.

Appearance:

Small vulture with characteristic flight profile, and distinct plumage with white body, white coverts and black flight feathers (in adults). Long, wedge-shaped tail, but not longer than wings are broad (as opposed to Lammergeier). Wings square with broad, full hand (slightly pointed in Lammergeier). Small head with thin bill. At long distance plumage of adults slightly similar to White Pelican, White Stork and pale Booted Eagles, but note wedge-shaped tail. Immature birds dark brown with paler coverts. Despite the less distinct plumage, the silhouette is similar to adults. Noticeably more active wing flapping and quicker wing-beats than in the large vultures.

Sound:

Almost never heard. May emit different grunting sounds and a slightly mallard-like "ga ga ga ga ga ga ga".
