Arctic Foxes were common and bred. Rough-legged Buzzards, Peregrine Falcons and merlins bred in average numbers, and hatching of chicks was recorded in two former species. White-tailed Sea Eagles occurredin small numbers, and observation of Short-eared Owl was made. Arctic Skuas were common breeders, while nesting of Long-tailed Skuas, Common Gulls and Herring Gulls was not confirmed. Willow Grouse were common breeders. Neither species of waterfowl was numerous.
Trampling by reindeers could adversely affect breeding success of birds.
