A medium-sized bird of prey with slaty grey upperparts, a dark moustache and white underparts barred with dark grey. It is the fastest of all birds, able to reach 300 kph in a stoop. It nests on cliffs and will chase off other raptors from the vicinity. For hunting they choose open country, taking pigeon-sized birds, but sometimes even Little Bustards and ducks. They tend to stay close to their breeding sites throughout the year, although northern birds also arrive in Extremadura to spend the winter.
