Breeding conditions:
|
| In three habitats (the larch woodlands with scattered stands at the Omolon river valley, in montane tundras of the Ukagirsky upland and in coastal tundras) lemming numbers were larger than in 1992, those of Arctic Fox average, and the number of skuas high. At the same time Snowy Owls, Rough-legged Buzzards and Peregrine Falcons Falco peregrinus were scarce. The number of breeding Great Knots Calidris tenuirostris was considered to be large (five broods of one to three chicks were recorded on 1 km2); high breeding densities were observed also for Whimbrel, Grey Phalarope and Temminck's Stint. Dotterel, Spotted Redshank, Sharp-tailed Sandpiper Calidris acuminata, Bar-tailed Godwit, Little Stint and Curlew Sandpiper were rare. In the last ten days of July large concentrations of Long-billed Dowitchers were observed at the marine coasts. Judging by the number of young birds, breeding was successful for most waders.
