Weather conditions: |
Short-term observations were carried out from 30 May to 8 August. According to reports of local people spring started later than normal, but low amount of accumulated snow and warm weather in late May resulted in close to normal phanology. The last intensive snowfall occurred on 27 May, and snow reduced to 10% of the total surface already on 30 May in the city and airport neighbourhood, but still occupied 90% of surface on the Zolotoy Ridge and afar off settlements. Tundra humidity decreased during June, and several small bogs dried out, but tundra surface became wet again in early August indicating abundant precipitation in July.
Bumblebees, overwintering mosquitoes and first flowers (e.g., cottongrass) were recorded already on 1 June. Water table on the Kazachka River peaked on 2 June. Passerines started egg-laying on 31 May, while nests of Herring Gulls and Glaucous Gulls on Alyumka Island contained 1 egg on 1 June. On this date we observed females ready for egg-laying in Wood Sandpiper, Long-toed Stint, Dunlin, Whimbrel, and complete clutches of waders were found on 5 June. Mosquitoes appeared en masse on 30 June. Many waders were seen with broods in late June, and the first duck brood was found in Common Eider on 30 June.

Breeding conditions:

Ermine was a single mammalian predator observed. Avian predators were rare. A single nesting pair of Rough-legged Buzzards was found on rocks near Dionisia mountain.Records of White-tailed Sea Eagle and Gyrfalcon were solitary, while owls were not seen. Long-tailed Skuas bred in usual numbers, and nest was found of a sinlge pair of Arctic Skuas. Large gulls concentrated on lowlands underflooded with brackish sea water. Apart of traditional localities isolated pairs of Herring Gulls nested in the Kazachka River floodplain, where they were not found previously. This probably reflected further increase of numbers of these birds.
Most birds bred in usual numbers. Common Sandpipers were found nesting, although they were considered vagrant previously. Observations were made of territorial Terek Sandpipers. Numbers of breeding Arctic Terns decreased compared with 2000.
Although loss of clutches and chicks was recorded broods of waders, gulls, passerines and even ducks were common, which indicated favourable conditions for reproduction this summer. Breeding success of tundra birds was probably average.
