high

Breeding conditions:

Crop of mushrooms and berries (Cloudberry, Clusterberry and Bog bilberry) was very heavy.
Arctic Foxes, Red Foxes, Brown Bears, and fresh tracks of these animals were not seen. An adult Ermine was seen on a creek slope. A brood of Snowy Owls of two flying juveniles accompanied by an adult bird was seen on 17 August. Alarming Rough-legged Buzzards were seen in 3 sites along rocky coast of the Lavrentia Bay. Among skuas adult and juvenile Long-tailed Skuas were often recorded, but not other species.
Broods of Common Edider, Long-tailed Duck and Pintail were recorded on lakes in the settlement vicinity. Broods of Greater Scaup were found on almost every relatively large lake. Grouse were very rare. Mass migration of Sandhill Cranes started on 10 August in the morning and continued for 3 days in a row. Flocks of hundreds birds were passing towards Alaska from approximately 9-00 until 16-00. Intensity of migration decreased dramatically from 14 August, when solitary flocks continued to fly.
 

Rodent dynamics:

Rodent numbers were probably high, as we saw recent signs of activities of Tundra Voles and lemmings during the whole period of stay. According to reports of local people feral cats were catching lemmings even in the buildings. Arctic Ground Squirrels were common and locally numerous.
