Peregrine Falcon

Peregrine Falcons (Falco peregrinus) are large and powerful birds of prey which are at the top of the food chain in London. Females, known as Falcons, are Crow sized birds; they have long, broad, pointed wings and a relatively short tail. Males, known as Tiercels are exactly the same but up to a 1/3 again smaller than females. Both are blue /slate-grey above, blackish head with an obvious black 'moustache' that contrasts with its white face. Adult under parts are white with fine barring. Feet are a prominent yellow and appear huge in relation to the bird’s size.

Juvenile peregrines are very similar other than that the upperparts specifically, and lower parts have a brown tone to them with the breast and lower parts streaked rather than barred. Legs also are a duller yellow.
