Breeding conditions:
|
| Both Siberian and Collared Lemmings were abundant, while neither Arctic Foxes, nor Wolves or their traces were seen in the period of studies from 2 to 30 July. All inspected dens of Arctic Foxes remained uninhabited for a number of years, although winter hunting on foxes was successful as reported by local people. Ermines were rare. Supplemented by good weather the almost complete absence of predators led to successful reproduction of numerous birds. Particularly high density in the study area was reached by Bar-tailed Godwits (up to 5 records per 1 km) and Willow Grouse, while common species included Turnstone, Rough-legged Buzzard (about 3 pairs/5 sq.km), thrushes, Pomorine Skua, Arctic Tern, Bluethroat. Temminck's Stint, Grey and Ringed Plovers were also seen.
