This is one of the rarest raptors in the world with an estimated breeding population of about 750-850 pairs. It is also the southernmost raptor in the world. It is a coastal bird, surviving on offshore islands. This is an immature showing gray legs and feet and dull pinkish cere. This near threatened species feeds largely on carrion, but it has been heavily persecuted on the Falklands by ranchers who believe kills newborn lambs. It is now protected but remains virtually absent from Port Stanley where formerly common. It takes five years to reach full adult plumage. Canon PowerShot SX50 HS
