Breeding conditions:
|
| Tracks of Arctic Foxes were recorded almost daily, but wader density was high, and until mid July intensive predation was not observed. Perhaps, in winter and spring lemming numbers were high enough to support the Arctic Fox population. Buzzards were breeding at a low density and had small clutches. Among skuas only Long-tailed was found breeding with low numbers. Many hundreds of waders (mostly Red Phalaropes, Ruffs, Dunlins, Pectoral Sandpipers, less often - Spotted Redshanks, Long-billed Dowitchers) were feeding in the marshy lowlands on 3-5 July. Ruffs were then migrating west, Red Phalaropes and Pectoral Sandpipers - east.

Rodent dynamics:
|
| Siberian Lemmings were rarely met, but numerous winter nests and other tracks were found. Also nearly all droppings of Herring Gulls at the colony on Arangastaakh Island in Anabar Bay (about 100 nests) contained lemming remnants, and gull clutches were large. According to somewhat contradictory interview data lemming numbers were relatively high in 1996-97, but a pronounced peak was not recorded.
