Аннотация: Data on barnacle goose nest density and distribution collected on Vaygach Island (in the vicinities of Varnek, Lyamchina and Dolgaya bays (southern, southwestern, and northwestern Vaygach, respectively) in 1986–1988, 1995–1997, and 2013 are presented and compared. The numbers of geese nesting there have clearly increased over the past 15 years. At least one new colony, of about 8000 nests, was established at the mouth of the Yunoyakha River (Lyamchina Bay) and the number of nests within a monitored plot near Dolgaya Bay increased. We can assume that at present 50,000–55,000 barnacle geese occur on Vaygach Island by the end of the breeding season. Taking into account that not all parts of the island were surveyed, this number could be even higher.
