Breeding conditions:

We found breeding Rough-legged Buzzards and common breeding Arctic Foxes from the Teyukuul River mouth to the northern extremity of the Kyttyk Peninsula. Short-eared Owls bred on Kyttyk to the west of the Teyukuul River (western). Peregrine Falcons occurred at a high density. The Snowy Owl and Pomarine Skua were not recorded. This could be due to the insufficient abundance of voles for these species, or a late increase in rodent numbers,after the end of the spring migration of owls and skuas in the area. Sandhill Cranes and Willow Grouse bred in average numbers.
Warm spring and hot summer led to earlier breeding and moulting of geese and swans. Juvenile geese fledged already in mid August, but it was not possible to evaluate geese breeding success. Reproduction was successful in waders, based on commonness of juvenile Pectoral Sandpipers, Red-necked Phalaropes and Long-billed Dowitchers on the mudflats of the Kyttyk Peninsula.

Rodent dynamics:
|
| In the study period from 21 July to 20 August we encountered sites with high and low abundance of rodents. Numbers of voles and lemmings were low on the northwestward route along the southern coast of the Chaun Bay to the Teyukuul River (western) at the west. Voles were first recorded in the Teyukuul River mouth, and then they were found everywhere farther on the transect to the northern extremity of the Kyttyk Peninsula.
