Breeding conditions:

The abundance of lemmings was lower than moderate, of Arctic Foxes - moderate. The density of breeding waders was low, but relatively high for ducks. Little Stint, Pacific Golden Plover, Pectoral Sandpiper, Grey Plover, Curlew Sandpiper and Dunlin were alarming with broods. Herring Gull, Glaucous Gull, Long-tailed Skua and Pomarine Skua all bred at low or moderate density.
