Weather conditions: |
| The weather was warm, calm and sunny in the period of visit to the area on 24-25 July. The summer was cold according to reports from local people, and we observed a snow bank still present near coastal bluffs of the Kamakay Bay which is a rare event. Water level was low in laies, lagoons and channels which indicated predominantly dry weather during summer.

Breeding conditions:
|
| Arctic Foxes were not observed but their tracks were common on mud flats of lakes and streams. Brown Bears were numerous and we counted 5 animals on 25 July per 40 km of coastline. Birds of prey and skuas were not recorded. Breeding success of waders was probably high, as we observed chicks or alarming adults in Ringed Plover, Turnstone, Western Sandpiper, Dunlin and Red-necked Stint. Juvenile Western Sandpipers, Red-necked Stints, Dunlins, Pectoral Sandpipers and Ringed Plovers were feeding en masse on mud flats and shallow waters in the coastal area on Ven'yakatryn Spit and in the Kamakay Bay. Broods were recorded in Lapland and Snow buntings, and chicks in nests of House Martins.

Rodent dynamics:
|
| Numerous burrows and undersnow nests, as well as bodies of Collared Lemmings were found in a hilly sedge-cotton-grass tundra near Ryrkalen Cape, which indicated high lemming abundance in 2004. High rodent numbers and successful reproduction of Arctic Foxes in 2004 were also reported by local people. Arctic Ground Squirrels were common in the Kamakay Bay vicinity.
