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:

Sparrow-sized, brown and streaked passerine with slate-grey head and chest. Bill thin and warbler-like, head rounded. Narrow, pale wing-bars. Often forages on ground in a crouched manner, creeping or hopping with legs almost hidden. Flicks wings and tail when restless. Secretive behaviour, except when visiting feeders and when singing from tree tops.

Sound:

Contact call a dry, thick trill "trrr", and a short King Fisher-like, high-pitched "zeep". Song a fast and evenly paced, high pitched stream of clear notes. No consistent phrasing. Similar in timbre to Robin, but does not vary tempo or pitch nearly as much. Often compared to the sound of a squeaky wheelbarrow.
