Appearance:

Largest falcon. Heavily built. Grey upperparts and white, speckled underparts. Juveniles with browner plumage than adults, blue-grey legs and longitudinal streaking below. Diffuse moustache-stripe, and the whole head seems dark at distance, lacking a defined cap. Rounder and broader wings, longer tail and bulky belly distinguishes it from Peregrine. Underside of wings with dark coverts in contrast to pale base of flight-feathers. Extremely powerful, but slower flight action than Peregrine.

Sound:

A coarse, drawn out, Peregrine-like "kaaawt", with emphasis on ending, is repeated in series. Much slower paced than in small falcons, and deeper and with different attack than in Peregrine. Also shorter, coarse warning-calls.

Appearance:

Rufous red face, throat and chest, framed in slate grey in adults of both sexes. Olive brown to grey upperparts and dull white underparts. Head rather large, and body rather stocky when plumage puffed, despite thin bill and slender legs. Juveniles lack the red front and are heavily spotted in buff on a dark brown body with barred chest. Adults pretty unmistakable when seen well. Flight usually low and darting, with quick changes of directions before disappearing in thick bushes. Posture usually erect with frequent flicking of tail and wings.

Sound:

Alarm call a thin, electric "tick", often in series with decelerating tempo. Song medium to very high pitched, with mostly clear tones with a liquid quality. Timbre reminiscent of Wren or Dunnock, but with a much more varied structure and tempo. Pitch ranges from very high to low, almost thrush-like, notes. No recognizable motifs. Often ends on a rising or falling pitch, giving it a "Chinese" accent.
