Black Redstart (Phoenicurus ochruros)
Gyrfalcon (Falco rusticolus)
Male: Charcoal to black plumage, with rufous red tail, pale belly and pale wing-panel (south-eastern subspecies with rufous belly and no wing-panel). Female: Grey brown overall, except rufous tail. Lacks the orange tinge to breast and belly of female Common Redstart. Juveniles resembles the adult female, and lacks the buff speckles of congeners. May jump around on the ground like CR, but are more prone to run. Also shows a more erect posture.
Sound:Song consists of three parts and is distinct if heard well. It opens with some clear notes that may form a trill, which are then followed by a pause. Next part is rather unique, and sounds as if shaking a handful of gravel. The phrase then usually closes with a couple of trills. The "gravel-part" does not carry as far as the rest of the song. Alarm call is a chat-like alternation between short, high-pitched "wit" sounds, and series of hard and dry "teck".

CCLargest 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.
