Weather conditions: |
| Snow started to melt earlier than usual in 2001, and rise water level was not high in spring. Small amount of precipitation in June and July resulted in lower level of water in rivers and streams compared with 4 previous years, and some water bodies dried out. Extremal weather events were not noted during incubation and hatching periods. First rains, causing summer flood, occurred in mid August.

According to reports of local people White-fronted Geese dispersed in tundra and start nesting immeadeately after arrival. Despite droughty summer, observations of geese broods, as well as broods of Pintails, Teals, Eiders, Ringed and Lesser Sand plovers, Red-necked and Little stints, Dunlins, Herring Gulls and other birds, indicated successful reproduction.
Presence of spawning Capelin Mallotus villotus near sea coast in big numbers in 2000-2001 drew most of non-breeding and immature Herring and Slaty-backed gulls away from coastal tundra until 20 July, which positevely affected bird reproductive success. The latter is also dependent on activities of Brown Bears, due to their high numbers. Until start of salmon spawning in mid July bears wander in tundra and destroy bird clutches. Some animals make regular visits to nesting colonies of gulls and eiders. In August 2001 bear females with young of this and previous year were seen on spawning rivers more often than usual, including 3 records of bears with 3 young.
Snowy Owl was seen twice hunting Arctic Ground-Squirrels in 2001 near shore of Pekulneiskoe Lake, and 8 White-tailed Eagles (mostly joung) were seen from 20 August to the end of month in the mouth of the Kakanaut and Kautayam rivers. This makes an impression that numbers of birds of prey increased in the second half of summer 2001 compared with 1997-2000. Birds could migrate from continental parts of Chukotski Peninsula beyond Meinypylginski Ridge to south-west, where dry summer resulted in fires.
