WEATHER
CONDITIONS

|
Weather conditions: |
| There was little snow during severe winter at eastern Taimyr. Strong and long-lasting snow-storms were rare. Spring was early, cold and developed quickly, which resulted in a complete snowmelt on 1-2 June, which is 1-1.5 weeks earlier than usual. Flood was low, and the Khatanga River became ice-free near Khatanga settlement on 7 June, which is a week earlier than usual. Summer was cool and rainy, with frequent thunderstorms, but without snowfalls. In autumn snowcover established earlier than usual during the last 10-day period of September.

Breeding conditions:
|
Arctic Foxes were rare and did not breed. Rough-legged Buzzards had on average 3 chicks in nests, which is fewer than in "lemming" seasons. Among skuas Long-tailed Skuas were numerous, but they almost did not nest and were collecting food near human settlements.
Start of breeding season was generally favourable for reproduction of birds. Birds arrived earlier than average, even late migrants like phalaropes and Arctic Tern appeared in first days of June. Geese and duck numbers were lower than usual. Predation, primarily by gulls and skuas was heavy, and wader broods were rarely seen.
