Gyrfalcon

Largest of falcons: can grow up to 60cm (2 ft) in height

NorthernLight

The gyrfalcon is the world’s biggest falcon and a bird of prey. Its plumage varies depending on where it is found, with birds ranging in hue from all-white to dark brown. Morphs are color variants that might be “white,” “silver,” “brown,” or “black.” Cream streaking on the nape and crown distinguishes the brown gyrfalcon from the peregrine, as does the lack of a well-defined malar stripe and cap.

The black morph’s underbelly is heavily black-spotted rather than neatly barred like the peregrine’s. Gyrfalcons of the white kind are the only falcons that are primarily white. Silver gyrfalcons resemble a bigger light grey lanner falcon. Adults are darker and browner than juveniles. The female falcon, like other falcons, is substantially bigger than the male.
