BIOTIC CONDITIONS

Rodents abundance evaluation:

average

Breeding conditions:

Arctic Foxes were common and bred.
Birds of prey and skuas were not recorded, but we observed single Snowy and Short-eared owls, and Ravens. A Snowy Owl with brood patch was photographed, but neither nest, nor chicks were found. Glaucous-winged Gulls and Glaucous Gulls occurred in small numbers; seabird colonies were used for nesting by auks, Pelagic Cormorants, Kittiwakes and Red-legged Kittiwakes. Northern Fulmars and Red-faced Cormorants were numerous. Waterfowl were rare non-breeders, with the exception of Harlequin Ducks, common on the sea. Breeding waders included common Rock Sandpipers and rare Semipalmated Plovers.
 

Rodent dynamics:

Approximately 20 Brown Lemmings (the only species of rodents on the island) were encountered during the season, which was considerably higher abundance compared with previous years, when 1-2 lemmings had been seen. Lemmings were recorded not only in spring, but during the whole summer, and their abundance was evaluated as average.
