Appearance:

Large and athletic falcon. Adults slate-grey above. Underparts white with black barring. Head almost black. Juveniles with brown tone to plumage, coarse longitudinal streaking below and paler head. Differs from the smaller falcons by less pointed wings, heavier hips and short tail. Highly contrasting and broad moustache-stripe. Smaller than Gyrfalcon with a more compact silhouette. The wings are not as broad, and belly not as deep. Underside of wings evenly barred, without contrasting coverts. Flight-pattern can recall Fulmar, with shallow, stiff wing-action.

Sound:

A harsh, drawn out "kiaaaa" with emphasised endings repeated in series. Much slower than Merlin, but higher pitched than Gyrfalcon. Also shorter, coarse warning-calls.

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".
