Abstract

This paper analyses the results of bird counts carried out over the period of 1996–2017 in the Innermountain Province of Dagestan. The avian species composition, average population abundance, and ecological pattern of avifauna in a difficult-to-reach mountain area of the republic are described for the first time. Cluster analysis showed that population patterns of the considered sampling areas were not only similar, but also unique because of high heterogeneity of habitats and, consequently, faunal differences, which emerge in mountains under a lack of humidification. It is suggested that a specific pattern of the avifauna of Innermountain Dagestan is provided not only by resident communities of typical mountain birds, but also by adapted populations composed of migratory birds of valleys that nest in mountains.
