Shaheen Falcon (Falco peregrinus peregrinator) has a rufous wash on the underside with black speckles. The black hood over the head, the yellow ring around the eyes (similar to most other falcons), huge talons and a no-nonsense beak make these birds look mean and menacing, but they are more famous for something else! Yes - the dive!
It is renowned for its speed, reaching speeds of over 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest extant member of the animal kingdom. While its diet consists almost exclusively of medium-sized birds, it will occasionally hunt small mammals, small reptiles or even insects. Reaching sexual maturity at one year, it mates for life and nests in a scrape, normally on cliff edges or, in recent times, on tall human-made structures.
