Two Arctic Fox dens surveyed in the Atchavyvrer River basin were uninhabited, but one fox was seen as well as their fresh tracks in three locations. Brown Bear female with 2 yearlings was seen there as well. Long-tailed Skuas were common, and they were seen attacking a Snowy Owl to the south of Kynetlyun ridge. Several colonies of Herrign Gulls were found on lake islands in the Teninveem River delta. Breeding of birds of prey was not recorded.
Bird numbers were relatively high. We found nests and broods of Sandhill Crane, Western Sandpiper, Dunlin, Grey Phalarope, four nests of Common Eider with clutches and two more predated. Some eggs were damaged by skua in one of two inspected nests of Long-tailed Duck. Clutches were destroyed by predators in 4 found nests of Emperor Goose. Territorial pairs of the latter species and Sandhill Crane were numerous in late May when we passed through the Achavyvrer River basin on all-terraine vehicle, but neither pairs, nor nests were not found in July. An Emperor Goose egg cashed by Arctic Fox was discovered. Generally, reproductive success was, probably, average, but low in some species.
