Abstract

The article analyses the number of brown bear Ursus arctos Linnaeus on Zavyalov island and describes its possible migration routes between the island, the mainland and neighboring islands. The observations from boats and aerial surveys showed that the island is home to 11–17 brown bears of all age and sex groups. It is found that the entire area of the island, except for the rocks, has the same common density of brown bears as in the similar natural conditions of the northern coast of the Sea of Okhotsk. The article describes possible migration routes of brown bears between the mainland coast and Zavyalov island taking into account the prevailing sea currents, winds and ice conditions.
