Coal Tit (Periparus ater)
Gyrfalcon (Falco rusticolus)
Appearance like a small Great Tit in black and white. Back led-grey (olive in British sub sp.), underparts off-white. Diagnostic elongated, white neck-patch and big triangular bib. Double wing-bars, small head and short tail.
Sound:Song: Various repeated motifs, consisting of two to three notes with alternating accents. Slightly similar to Great Tit, but faster, not so metallic and with a less full tone. Can be mistaken for Marsh Tit when singing single or double notes, but tone is softer and notes more clearly separated (if disyllabic). Call: short soft and clear "piu", first rapidly rising and then falling in pitch.

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.
