Changes in numeric abundance and distribution limits of 25 indicative bird species of the Lower
Kolyma from the late 1970s until nowadays are examined. The reconstruction of the fauna composition
in typical landscape subdivisions has been established. Populations of the sandhill crane,
Bewick’s swan, the tundra bean goose, and the peregrine falcon have been found to keep growing.
Some typical bird species of the northern taiga and bush-tundra have been marked to expand northwards,
while the abundance of many tundra species with formerly dense populations (long-tailed
duck, wading birds – probers of moss sod, Lapland longspur) has conspicuously declined. |
