Studies of the ecology and behaviour of Snowy Owl have been carried out on Wrangel Island since 1990. In summers the major work takes place in two study areas of 44 and 40 km2. Breeding rate, chick growth rate and breeding density are measured. The number of breeding Snowy Owls in the study area of 44 km2 fluctuated from 7 to 14 pairs. Clutch size in Snowy owl depends not only on the spring density of lemmings, but also on the conditions of wintering. Interspecies relations between Snowy Owls and Arctic Foxes take the form of complicated territorial competition. The established territorial relations in mixed settlements of the owls and foxes to a great extent determine the spatial distribution of Snow goose, Brent Goose, and Common Eider. Irina E.
