Breeding conditions:

Red Foxes were rarely seen, although several inhabited dens were recorded in the area. Brown Bears were recorded on average 1-2 times per day. Tracks of elks were rarely seen, and a single reindeer was recorded in 3 years. We observed tracks of wolves occasionally, and a single Arctic Hare was known to inhabit study area.
Birds of prey were rare, but Rough-legged Buzzards and Golden Eagles bred, while Peregrine Falcon, Gyrfalcon and White-tailed Eagle were non-breeders. Short-eared Owl was very rare and did not breed. Arctic Skua was rare breeder.
White-billed Diver was very rare, but bred successfully in 2005, as we observed a brood with a chick approximately one third of adult bird on 29 July. We recorded 12-15 broods of Red-necked Grebes and approximately 10 broods of Sandhill Cranes in the study area in 2005. White-fronted Goose was a common breeding species with mean clutch size 3.25 eggs. Apparent hatching success was 0.47 (n=34) and 0.33 (n=6) in White-fronted and Emperor geese, respectively.
Redpolls, Little Buntings and Yellow Wagtails were numerous among breeding passerines, while Red-throated Pipits, Dusky and Arctic Warblers and Lapland Buntings were common.
