Spotted Crake (Porzana porzana)
Gyrfalcon (Falco rusticolus)
Small, secretive bird, usually only heard and not seen. Buff under tail-coverts and zigzag-patterned wings are diagnostic, and separates it from all other small rails in the region except American migrant Sora. Stocky build, with speckled underparts and short yellow bill with red spot at upper base.
Sound:Loud and far reaching song uttered with relentless stamina for hours on end. A monosyllabic, resonant and drawn-out "huiiit". The pith rises towards the emphasized end of the call, which is repeated about once a second. Often compared to the dripping of water. Mostly heard at night, and often i duet with mate. The female answers the male with a slightly deeper and softer call, giving the impression of one bird giving a disyllabic call.

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.
