Avifauna Structure Of Boreal Zone Open Habitats (Ishim Plain, Western Siberia)
In 2014‒2016 field seasons, bird censuses were conducted on 34 flyways in seven different types of open habitats of the Russian part of the Ishim River region. Ninety-five species from 72 genera from 10 orders were registered. It is established that the taxonomic composition and ecological structure...
