BIOTIC CONDITIONS

Rodents abundance evaluation:

high

Breeding conditions:

Breeding conditons were generally favourable for all birds. Voles were numerous and were met few times every day. Rodent specialized avian predators (owls and buzzards) were entirely absent; among skuas only Long-tailed was recorded. Seabirds were preyed upon by Herring and Glaucous gulls, and Ravens, in stony talus - also by Arctic Foxes.

Summary of fauna studies:

Results of monitoring of Kittiwake, two murre species, Crested and Least auklets breeding can be obtained from U.S. F. & W. Service
