Appearance:

Slender and elegant harrier, with narrow wings and four "fingers". Adult male easily recognized by very pale grey and white plumage, with diagnostic wedge-shaped, black wing-tips (outermost primary grey). Female and immature birds often difficult to tell from Montagu's Harrier and Hen Harrier. Adult female differs from Montagu's by lack of dark band on upper wing, and by diffuse, sooty inner underwing. Pale bands do not reach wingpit, and under coverts are darker. Differs from female Hen Harrier by noticeably slimmer wings (both hand and arm) and only 4 fingers (but beware moulting Hen Harriers). Immature similar to Montagu's with unstreaked, rufous underparts. Differs in pale tips of inner primaries, and dark half-collar and pale "boa".

Sound:

Some calls similar to Montagu's and Hen Harrier, but display call quite diagnostic. A thin, vibrating trill "peerrrrrrrr".

Appearance:

Anonymously brown and dark brown warbler. Slender bill, short rounded wings and broad waist and tail. Base colour varies from olive-brown to yellowish buff. Streaking also varies from diffuse to marked, and is most prominent on sides of throat and upper chest. juveniles are more streaked than adults. Rufous/olive fringes to tertials are broader on outer side (as opposed to Pallas' Grasshopper Warbler). Secretive bird. Generally discovered by song.

Sound:

Song insect-like and high-pitched. A monotonous stream of even clicks similar to a running fishing line. Maintained for seemingly endless periods, and often hard to locate. Song most similar to Savi's Warbler but is slower (each click more separated), and higher pitched with a metallic, ringing quality. Short sequences of song also functions as contact call. Also a Robin-like "tick".
