Breeding conditions:
|
Hatching of Common Eiders in vicinity of Dyrovataya and Laymchina bays started in the third week of July, and peaked from 1-10 August. Afterwards, a single clutch still containing eggs was found on 13 August.
Reproductive success of Glaucous Gulls was very low, and they occasionally destroyed clutches of Common Eiders. In general, breeding success of eiders and Barnacle Geese was high. Breeding performance of geese and swans was, probably, affected to the largest extent by traditional hunting of native people (nenets). A pair of White-tailed sea eagles nested in vicinity of Dyrovataya bay, took adult eiders, and thus substantially affected distribution of their broods.

Summary
of fauna studies: |
| Composition of bird fauna in coatal tundra and on sea was described qualitatively and quantitatively. Approximate age and number of chicks, and number of adult birds assicoated with broods were recorded during brood surveys of Common Eiders and Barnacle Geese.
