Gyrfalcon (Falco rusticolus)
Long-eared Owl (Asio otus)
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.

A medium sized, brown and long-winged owl, with long ear-tufts and deep orange eyes. Only half the size of Eagle Owl. Differs from the more similar Short-eared Owl by darker (orange) eyes, longer ear-tufts and heavily streaked lower belly. In flight, note paler wing-tips (only finely barred, not tipped black).
Sound:Song a series of very deep, monotonous "hooooo"s, quite widely spaced. Uttered about once every 2-3 seconds. Sometimes rises in pitch, but with each "hoo" being constant. Rich repertoire of calls. Other sounds include; a nasal "eeeeeaaa" reminiscent of Collared Dove, nasal mewing and bill clicking.
