Ornithofauna of the national park "Sengileevskie mountains"

This paper presents materials from a long-term study of the avifauna of the National Park «Sengileevskie Mountains» and territories planned for inclusion in the protected areas. The purpose of the work is to update and supplement the faunal list of the study area, as well as to assess species diversity and subsequent use of data to assess the results of environmental activities. Particular attention is paid to identifying the species composition of the avifauna of protected areas, as one of the main components of the national park ecosystem. The results provide materials taken from the state cadastre of fauna for 2018-2020, which contained 143 taxa, later supplemented in the course of work by another 26 species. 13 species of birds were identified, recorded only on the Turgenev Islands, which increases the ecological value of the archipelago and increases the chances of including these territories in the national park.
