The Striated Caracara, (Phalcoboenus australis) is a bird of prey of the Falconidae family. In the Falkland Islands it is known as Johnny Rook.
The adults plumage is almost black in colour, while the legs and lores are orange and the neck is flecked with grey. The first year juveniles have an orange or light red down, which they lose after their first moult. Full adult plumage is acquired only in the fifth year.
It breeds in several islands in the Tierra del fuego, but is more abundant in the Falklands where the population is estimated at 500 breeding pairs.
