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:

Upper back strongly barred, lower back all white (barred in south-east Europe subspecies). Underparts streaked. Whole crown red in male. Vent pinkish red, not deep red as in Great Spotted, and less marked. Most likely to be confused with Middle Spotted Woodpecker, but is clearly bigger, has longer bill and black moustache stripe connects to base of bill. Easily recognized in flight due to strong wing-bars and white lower back.

Sound:

Drumming noticeably longer and more powerful than Great Spotted, with accelerated ending (similar to Three-toed Woodpecker but faster). Contact call similar to Great Spotted, but slightly deeper and softer; "kjuk".
