Biodiversity of ornifauna on the territory of the Chograisky Reserve

Abstract

The article is devoted to the biodiversity of the ornifauna on the territory of the Chograisky Reserve. It is noted that the reserve is a center of attraction for a large number of waterfowl and, first of all, rare and endangered birds. It is shown that the reserve is geographically isolated and birds tend to water bodies located on the paths of seasonal bird migrations. Information on the biodiversity of bird species is presented. Of the vertebrates found in the Reserve, birds are the most representative in terms of species composition. The total number of bird species registered here is about 90 species. Taking into account biotic links of birds with water bodies, such groups as waterfowl, near-water birds and occasional birds were identified. Depending on the nature of nesting, method of feeding and degree of attachment to a water body in the development cycle, the largest number of species are surface waterfowl and diving species. birds are indicators of environmental conditions. High indicators of species diversity indicate stability and favorability of bird habitat factors on the territory of the Reserve. At present, a fairly stable system of bird communities has been formed in the area.
