Appearance:

Medium sized, green woodpecker with black mask. Crown red in all plumages. Females with black moustache stripe, males with red framed in black. Juveniles heavily marked with small black and white spots all over, and less prominent black mask. Bigger and more heavily built than Grey-headed Woodpecker, with longer and stouter bill. Often foraging on the ground. Flight undulated.

Sound:

Song similar to Grey-headed Woodpecker, but not as soft and fluty. Each phrase consist of a series of short "klee", with a laughing quality. Pitch drops slightly throughout the phrase, but not as markedly as in Grey-headed, and tempo is fairly constant (no ritardando). Short "kek" calls when excited and in flight. Drumming of 1.5 seconds duration with decelerating tempo, but not often heard. Another call is similar to Black Woodpecker; a series of resonant "klit-klit-klit-klit-klit-klit", but is less clear, has a more determined start and has less obvious rising pitch at the end of each syllable.

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.
