Birds of High-mountain Daghestan, A report based on two decades bird survey

The paper is based on 19 years (19982017) of the avifauna monitoring in High-mountain Daghestan. Each of 11 bird communities of the study area is characterized by its whole set of birds, including the rarely occurred species since the latter promotes the formation of a unique pattern not only of an individual faunal community but also the entire avifauna of the region. It is assumed that a specific avifauna pattern of High-mountain Daghestan is determined not only by resident communities of typical mountain birds but also by nesting in the mountains adapted populations of migratory birds of the plains. The analysis of the collected material provides a picture of the species diversity and territorial distribution of birds and helps to understand the avifauna resource capacities of High-mountain Daghestan.
