Gyrfalcon (Falco rusticolus)
Buzzard (Buteo buteo)
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.

Small head, short, thick neck, quite broad wings and fairly short tail. May be confused with a range of different species due to the highly variable plumage. Underparts range from almost white to very dark. Plumage tone ranges from chocolate to rusty brown. Dark morph usually with pale breast band. Shows 5 fingers like other Buteo, as opposed to small eagles. Tail lacks the broad terminal band of Rough-legged Buzzard. Neck thicker than in Honey Buzzard. Secondary coverts form a pale band in dark morph. Light morph typically with primary coverts forming black 'comma'. Soars with raised wings, but glides on straight wings.
Sound:Quite vocal. Most typical call a wailing, mewing "peeoooo". Quite similar to Rough-legged Buzzard, but the pitch falls more rapidly and is then sustained for the last part of the call.
