The White-tailed Eagle is the largest UK bird of prey. It has brown body plumage with a conspicuously pale head and neck, which can be almost white in older birds, and the tail feathers of adults are white. In flight it has massive broad wings with 'fingered' ends. Its head protrudes and it has a wedge-shaped tail. This Schedule 1 species went extinct in the UK during the early 20th century, due to illegal killing, and the present population is descended from reintroduced birds. Schedule 1 protection means it is illegal to disturb this species.
