Breeding conditions:
|
| Ermines were rarely observed in the mainland tundra to the south of the delta. Long-tailed Skua bred only in the mainland tundra to the south and south-east of the delta. Observations of the Snowy Owl during the summer were restricted to a single wandering bird seen on 16 June in the mainland tundra to the south-east of the delta. Rough-legged Buzzards bred at a low density, reflecting the low lemming numbers. They only nested on the riverside rocky bluffs of the Prymorky Edge and Tuora-Sis Ridge in the southern part of the delta, as well as on high banks of islands in the ancient seaside plain.

|
Rodent dynamics:
|
| The abundance of Narrow-skulled Voles was high on the mainland plain and mountain tundra adjacent to the southern part of the delta, where 17 animals were captured on 28-31 July with the effort of 162 trap-nights.
