White-tailed eagle only from the mainland. Also Rùm hosts large seabird colonies that make for viable prey, including eider, shag ("Phalacrocorax aristotelis"), auks and gulls; as well as one of the few in Britain of manx shearwater ("Puffinus puffinus"). Furthermore, mainly as a source of carrion, were a population of around 1500 red deer and 200 feral goats; otters and gulls were also numerous and available to kleptoparasitize. The birds to be used for reintroduction were gathered as nestlings from western Norway, as this is the nearest native breeding population. The young eagles were either kept in high grade fowl cages or

BirdLife International (2006) Species factsheet: Puffinus heinrothi. Downloaded from http://www.birdlife.org on 26/7/2006 Heinroth's shearwater Heinroth's shearwater ("Puffinus heinrothi") is a poorly known seabird in the family Procellariidae.
