Breeding conditions:

Arctic Foxes were rare, but bred. Among birds of prey Merlins and Northern Harriers were common, White-tailed Sea-eagles and Rough-legged Buzzards rare. Breeding was confirmed in Merlins and White-tailed Sea-eagles. A few records of single Short-eared Owls were made. Arctic and Long-tailed Skuas were rare, without signs of breeding.
A few species of passerines were numerous. Breeding Willow Grouse occurred in average numbers, while Rock Ptarmigans were rare. Observations of broods of ducks, waders and Black-throated Divers indicated average nest success.
