Appearance:

Breeding adult easily identified by white tail/rump combined with jet black under wing coverts and silvery upper wing. Immature with brownish back contrasting with pale, silvery upper wings and pale rump. Broad white collar, and lacks dark breast patch of immature Black Tern. Adult winter most liable to confusion with other terns, but upperparts much paler than Black Tern. Contrasting dark outer primaries and secondaries to rest of wing. Often retains some black under coverts even in winter which is diagnostic if seen. Slightly more compact than Black Tern and often recalls Little gull in shape. Bill noticeably shorter and thinner than in Whiskered Tern.

Sound:

Mostly silent away from breeding ground. Most diagnostic call a dry, rolling "krrrrrr-ta-ta" where the rolling is followed by one or two accentuated syllables, or just simply "krrrrrr". Used in excitement.

Appearance:

Small raptor with long tail and short, rounded wings. Quite similar to Goshawk, and female Sparrowhawks may approach male Goshawks in size (female much larger than male in both species). Upperparts grey in male, and brownish in female and juvenile. Underparts barred in buff in male, and brown barring in female and juveniles. Supercilium may be prominent in females. Less bulky than Goshawk, with more slender hips and less deep chest. The sharper corners of the tail is visible when soaring.

Sound:

Series of short "ke-ke-ke-ke-ke", with rising pitch. Less resonant and less full than similar call of Goshawk, and much faster. Also a short "peeaaaa", shorter and more squeaky than Buzzard.

Alarm call:
