Breeding conditions:
|
A single Arctic Fox was recorded on the coast, and a Red Fox was seen near the northern tree-line of sparse larch forest.
Amongst ducks Pintails, in flocks, were the most abundant birds, followed by White-winged Scoters and the least abundant ducks were Long-tailed Ducks. Arctic Redpolls, Rough-legged Buzzards and divers were common. Willow Grouse were rare, and only a single flock of 10-12 birds was recorded. A Snowy Owl was recorded once.

Rodent dynamics:
|
| On the sea coast in the mouth of the Ilin-Shar channel apart from Tundra Shrews and Middendorff's Voles that were commonly captured, only a single Siberian Lemming was captured. More species were discovered to the south, near the fork of the Ilin-Shar channel and the Yana river. Tundra Shrews and Northern Red-backed Voles prevailed in numbers there, Tundra and Middendorff's voles were less abundant, while Laxmann's Shrews and Siberian Lemmings were very rare.
