Neck with incomplete black band, creating contrasting, jagged edge. Heavy, goose-like flight.

Sound:

Song: Like a slow Black-throated Diver. Pitch slowly rising with a register break, progressing into a cyclic, two to four syllable, motif. Also various vibrating eerie descending calls. Often used as sound effect in horror movies.

Appearance:

Long tail, long neck and small head constitutes a characteristic profile. Adult males with grey head, females brown. Tail pattern is typical, and most obvious on adults: A broad dark terminal band and two or three smaller bands at base. Same pattern on flight-feathers. Middle of wing quite broad, creating a straight trailing edge when the bird is gliding with half-open wings. Wings held in a straight angle with primaries pointing slightly downwards when soaring. Tail often fanned and frequently twisted like a Kite to adjust position.

Sound:

Call an ascending, then descending; "pjuuuuu" much thinner than buzzards, and with a distinct register break when changing pitch. May be confused with newly fledged Buzzard chicks.
