Gyrfalcon (Falco rusticolus)
Red-backed Shrike (Lanius collurio)
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.

CCSounds:Recorded by Andrew Spencer,http://www.xeno-canto.org ,CC license
Male with brown back, pinkish white underparts and a bluish grey head with a black eye mask. Female more dull with barred underparts. Juvenile like female, but upperparts also barred . Tail brown with white edges in all plumages. Females and juveniles easily confused with other southern/eastern or vagrant shrikes like; Brown Shrike, Isabelline Shrike, Woodchat Shrike and Turkestan Shrike. Differs from those in white sides of tail, barred rump, mantle and scapulars, scaly underparts and dark or yellowish base of bill (not pink).
Sound:Call a hard "check check" (like striking two rocks together), and a variable nasal "twee" Song surprisingly varied with many expert imitations of small passerines, interwoven with bell-like ringing and dry chirping sounds. May be confusing and hard to identify if bird not seen. Song not very loud, but phrases can be very long.
