Site description This large 1,243-square-mile (3,180 sq km) uninhabited island lies in Karaginsky Bay along the northwest coast of Kamchatka (58°25'-59°15' N; 163°25'-164°29'E) on a major bird migration route. Ossora village, 34 miles (54 km) to the southeast on the mainland, is the nearest settlement.
Key Biodiversity The island is an important staging area for 600,000 migrating loons, ducks, cormorants, shorebirds and gulls. The most abundant ducks are common eiders, Steller’s eiders, harlequins, northern pintails, Eurasian wigeons, green-winged teal and scoters. The island also attracts 80 nesting species with the western wetlands inhabited by high populations of common eiders and lesser numbers of harlequin ducks, which nest in the mountains. Following the breeding season, western nearshore waters serve as key molting habitat for eiders, scoters, mergansers and harlequins. East coast sea cliffs support 39 colonies of an estimated 240,000 pairs of nesting seabirds. These include black-legged kittiwakes, common and thick-billed murres, pelagic cormorants, slaty-backed gulls and tufted puffins. Red-necked phalaropes, rufous-necked stints, dunlins and whimbrels are the most numerous of the shorebirds. Russian Red Data Book species regularly recorded include Steller’s sea eagle, gyrfalcon, peregrine falcon, and Aleutian tern.
Other notable wildlife: Whales, seals and Steller's sea lions inhabit surrounding marine waters. Domestic reindeer range freely over the island.

Protection status The entire island and 1.2-mile wide (1.9 km) marine zone is protected in a regional wildlife refuge (zakaznik) with management authority assigned to the Committee for Environmental Protection of the Koryak Autonomous Area. The zakaznik was designated a Ramsar "wetland site of international significance" in 1995.
