WEATHER
CONDITIONS

|
|
|
Weather conditions: |
| Spring was phenologically early. Low snow accumulation over the winter lead to its quick melting and minimal flooding. As a result for the first time in a 4 year-series the Bludnaya river floodplain was not flooded. The summer was relatively warm and dry, without snowstorms and heavy rains during the breeding season.

Breeding conditions:
|
Rodent-dependent raptors did not nest with the exception of a few pairs of Rough-legged Buzzards. No owls were seen. As far as skuas, only several Long-tailed Skua pairs nested in the area. Encounters with Arctic Foxes were regular throughout the summer, one pup was seen too.
Incubation in waders started in mid-June, which, judging from 4 years of observations, can be considered early for the region. The general breeding density was not high: in phalaropes and Ruff this could be a result of their re-distribution to the water-free in this season river floodplain. The high Arctic Fox abundance caused low breeding success in waders (8-18% in common nesting species).

|
Rodent dynamics:
|
| Judging from the number of lemmings noted in the area, their numbers dropped noticeably (ca. 3-fold in the Siberian Lemming, Collared Lemming was seen only once) in comparison with the previous, peak year; nevertheless they were periodically observed during the summer, although sometimes not for a few days in a row.
