The striated caracara, (Phalcoboenus australis) – considered as one of the most intelligent of the birds of prey – is a distinctive and charismatic raptor, which has the southernmost overall breeding distribution of any bird of prey in the world. It occurs rarely in the Tierra del Fuego area of extreme southern South America, but the main range of the species is the Falkland Islands where it is known as the flying devil, and also Johnny Rook. Both adults are similar in appearance. They have black to brownish-black upperparts. The upper back, neck and breast are streaked with creamy-white or pale buff. The dark tail shows a broad white terminal band. The striated caracara is an opportunistic feeder, often scavenging for carrion but also known to attack weak or injured birds.
