Weather conditions: |
| Winter and early spring were warm, with large accumulation of snow. Rapid warming occurred in mid May, and no snowfalls or returns of cold weather were recorded afterwards. Air temperature was 2.8øC above long-term average in May. Dates of snow melt, ice-break on rivers, lakes, Onemen Bay and Anadyr Bay were 5-10 days earlier than normal, and earlier in the city vicinity. Snow covered 10-20% and 70-90% of flat tundra surface on 26 May in the vicinity of Anadyr city and at a distance of 10 km, respecitvely. Snow cover remained in ravines, bush stands and on southearstern slopes by 5 June, accounting for 5-7% of the total surface. Flood was early, short and higher than average. June was warm and dry, which resulted in considerable drying out of tundra by mid month. Small amount of last year berries were still present in spring. Mosquitoes appeared in mass on 17 June which is very early.

Breeding conditions:

Red Foxes were seen several times, and their breeding was not confirmed. Short-eared Owl, Peregrine Falcon and Merlin were each seen once. We found one nest of Gyrfalcon, one of Rough-legged Buzzard and two of Ravens. Red-necked Grebes and Teals were rare breeders, while Pintails were common. Greater Scaup, Long-tailed Duck, Common Eider and Red-breasted Merganser were rare. Sandhill Cranes nested in small numbers not closer than 7 km from the city. Willow Grouse and Rock Ptarmigans were not seen, while Long-tailed and Arctic skuas were rare and did not nest. Herring Gulls occurred in aggregations from 80-100 to several thousand birds, the latter on the city wastefield. Glaucous Gulls were 10-20 times less common than Herring Gulls. Arctic Terns were very rare and their nesting pairs were not recorded. Aleutian Terns concentrated in marshes near entrance to Onemen Bay. Pacific Golden Plover, Pectoral Sandpiper, Ringed Plover, Wood Sandpiper, Ruff, Temminck's Stint and Long-toed Stint were rare among breeding waders, while Dunlin and Red-necked Phalarope were common. Curlew Sandpiper, Terek Sandpiper, Common Snipe and Whimbrel occurred in considerably lower numbers than in 2003.
Most species of passerines bred in lower numbers than in 2003. Wandering Redpolls were rare, and nesting birds were not found before 18 June. Snow Bunting, House Martin, House Sparrow, White Wagtail and Dusky Thush occurred in numbers similar to 2003. Generally breeding conditions were favourable for most species, except rodent-specialists.

Rodent dynamics:
|
| Microtine rodents were not seen, and their numbers were low based on the observed signs of activities. Arctic Ground Squirrles were common, or locally numerous.
