Аннотация: Birds of the upper Anadyr River (Chukotka Autonomous Area). P. S. Tomkovich. Summary. Only occasional information about bird species, their status and abundance has been available for the upper reaches of the Anadyr River, one of the two largest rivers of Chukotka Autonomous Area, extreme north-east of Asia. Low gently sloping mountains with alpine tundra on tops and larch forests in valleys predominate in the area. Observations made in spring and summer seasons of 1993–1995 around the field camp at 64°54′30′′ N, 168°36′40′′ E added by information from published sources are presented in this paper. In total 113 bird species are currently known from the upper Anadyr River basin. Breeding is confirmed for 64 species and is probable for other 18 species (72.6% of the regional avifauna). For the first time 58 bird species are listed for the region, and 6 of these species are recorded for the first time for Anadyrland: the Fork-tailed Swift (Apus pacificus), Black Woodpecker (Dryocopus martius), Olive-backed Pipit (Anthus hodgsoni), Gray Wagtail (Motacilla cinerea), Lanceolated Warbler (Locustella lanceolata), and White-winged Crossbill (Loxia leucoptera). Breeding records of some species extend their known breeding ranges; these are the Pintail Snipe (Gallinago stenura), Solitary Snipe (G. solitaria), Greater Spotted Woodpecker (Dendrocopos major), Common Cuckoo (Cuculus canorus), Olive-backed Pipit, Gray Wagtail, and House Sparrow (Passer domesticus). Comparison with formerly available data suggest population increase during the 20th century in the Greater Spotted Woodpecker, House Martin (Delichon urbica), Carrion Crow (Corvus corone), and Brambling (Fringilla montifringilla). Available data also indicate population decline in the Black-billed Capercaillie (Tetrao parvirostris) and possibly in the Dotterel (Eudromias morinellus).
