Appearance:

Like a pale, giant Tawny Owl. Yellow bill, long, evenly barred, tail. Eyes dark. Facial disks pale, unmarked and almost fused, lacking the dividing wedge of Tawny Owl. In flight, note lack of pale base of primaries and much slower wing-beats than Tawny. Mild facial expression, but very aggressive at breeding ground.

Sound:

Song: 6 -10 evenly spaced "ho"'s, starting silently and gradually rising in volume and pitch. Also an accented "ho-ho, ho-ho-it, ho-ho", three middle notes ascending and the two notes before and after descending. A variety of barking social sounds.

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.

Alarm call:
