WEATHER CONDITIONS

Season phenology: early

Weather conditions:

The season was early, warm and dry. By 20 June tundra was practically free from snow, ice remained in some bays of Pechorskaya Guba. As no sharp and prolonged coolings or other extremal events were recorded, the weather was favourable for bird reproduction.

Season humidity: dry

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Lemmings were not recorded, while signs of activity of voles were seen only near deserted human constructions and high hillocks. Number of Arctic Foxes in the study area was same as in previous 10 years, but they did not breed. For the first time wolverine was recorded, who destroyed one bird clutch and one brood with small chicks. Birds of prey were rare as in 1999, although Rough-legged Buzzards were slightly more common than usual. White-tailed Sea Eagles were not seen; in late June - early July Snowy Owls were seen daily sitting on elevated points. Numbers of gulls and skuas were lower than in 1999, and numbers of territorial breeding and non-breeding Bewick's Swans were the smallest for the period 1991-1999. Average clutch size in swans was 3.25ñ0.75. All nests of waders (Temminck's Stint, Dunlin, Red-necked Phalarope, Ringed Plover, Grey Plover) contained full clutches, and fist chicks of Dunlin appeared on 9 July.
