Breeding conditions:
|
Arctic Fox was seen once, Snowy Owls and Rough-legged Buzzards were not seen, while Pomarine Skuas did not bred. From 13 territorial pairs of Arctic Skuas 3 nested, with hatching in two of the latter on 22 and 24 July. Up to 3 White-tailed Sea-eagles were seen simultaneously in the area of Barnacle Geese colony during hatching, attacked small chicks.
Nesting was very late in Barnacle Goose, and peak hatching occurred on 13 July. Clutch size was very low (2.77ñ0.10, n=252). In total 1324 nests of Barnacle Geese were found on the marshes to the south of Tobseda and on Chayachyi Islands to the north among nests of Glaucous and Herring gulls. Nesting success of Barnacle Geese did not exceed 40%, while hatching was successful in 4 of 5 nests of White-fronted Geese. Nests in a small colony of Arctic Terns (at least 100 birds on 13 July) were deserted on 15 July.
