Breeding conditions:

Weather conditions in early July were quite favourable for birds but lemmings were not recorded. Arctic Foxes did not breed but still predated birds nests. The employees of Terpyai-Tumus arctic station recorded that in winter Arctic Foxes even fed on their allies which had been caught in traps. One Wolf Canus lupis den was found. Of rodent-feeding birds, only Rough-legged Buzzard bred (one nest found in the south of the survey area); breeding was observed also in Herring and Glaucous Gulls. Pomarine and Arctic Skuas moved in small flocks. Long-tailed Skuas formed large flocks together with terns and Sabine's Gulls Larus sabini.
In early July only a few nests of waders were ruined, while nests of gulls and divers were continuously predated "in front of our eyes". It is supposed that although hatching success was high, chick mortality later was relatively large as well.
