Gyrfalcon (Falco rusticolus)
Grey-headed Chickadee (Poecile cinctus)
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.

Like a Willow Tit with dark brown hood, brown back and warm brown flanks. Fluffy overall look, with very large dark bib. Summer plumage often looks "newly washed" and untidy. Tail slightly longer than in Willow Tit, and flight is less undulating. Not shy.
Sound:Voice quite similar to Willow Tit. Song: Often vibrating or rasping notes repeated in Willow Tit-like structure, gradually falling in pitch "trrrrrr trrrrr trrrrr". Call: Nasal Willow Tit-like "chee chee chee" , "ti ti chee". Other sounds: Chirping, bubbling sounds resembling Willow Tit, various other high pitched sounds.
