Latitudinal Features of Nest Success of Passerine Birds (Passeriformes) in the Ob Forest Tundra and Yamal Peninsula

— Success in egg incubation and chick rearing in 18 passerine bird species has been analyzed based on the results of observations on the survival of 12 610 eggs in 2083 nests found in the Ob forest tundra and the southern, central, and northern Yamal peninsula. It has been found that a northward inc...

Description
Summary:— Success in egg incubation and chick rearing in 18 passerine bird species has been analyzed based on the results of observations on the survival of 12 610 eggs in 2083 nests found in the Ob forest tundra and the southern, central, and northern Yamal peninsula. It has been found that a northward increase in nest success is observed in the direction from the Southern Urals and Kazakhstan to Yamal but not from the Baltic Sea to Yamal. In the total forest tundra–subarctic tundra space, nest success increases to the north in one group of species (the common redpoll, Lapland longspur, and common chiffchaff) but decreases in another group (the horned lark, red-throated pipit, bluethroat, and willow warbler).
