Weather conditions: |
| A connection between channels from Vaamochka and Pekulneyskoe lakes with the sea was established in usual dates - mid June. Accordingly, spring flood did not prevent initiation of breeding by birds, as it happenned in 2004. The amount of precipitation was not high in June and July, and long-lasting rains causing raise of water level started in early August. Extreme weather events were not recorded during breeding by birds.

Breeding conditions:

Regular observations of broods of Common Eiders, Ringed Plovers, Lesser Sand Plovers, Dunlins and Whooper Swans indicated successful breeding of these birds. In contrast, broods of White-fronted Geese were recorded considerably less often than in 2005. For the first time since the start of observations in 1997 moulting Whooper Swans (3 adult birds) were recorded on the Pekulneyskoe Lake in early August. Human impact was still present in accessible colonies of Common Ediers and herring Gulls. Three adult divers, including one White-billed Diver, perished during the breeding period in fishing nests on the Pekulneyskoe Lake. Numbers of Brown Bears continued to increase and these animals had strong impact on nest success by birds.
Autumn was very late and calm, and mass departure of birds was delayed compared to long-term average. Mass departure of White-fronted Geese from the Rynnatanmelgyn River valley continued until 24 September, while normally it terminates before 20 September. Mass migration of Ross's Gulls was observed in the vicinity of the Russkaya Koshka Spit in the Anadyr Bay on 3 December, while normally it occurs in late October.
