Abstract
National Natural Park “Kolsay Kolderi”, located in the Northern Tien Shan. 81 species of birds has been identified and data on the distribution are provided as obtained results of these investigations. The study showed that in these two years, the abundance of such birds as the Grey Wagtail Motacilla cinerea, Greenish Warbler Phylloscopus trochiloides, Blue-headed Redstart Phoenicurus caeruleocephalus, Mistle Thrush Turdus viscivorus and Linnet Acanthis cannabina were stable, and the rests there were fluctuating fluctuations. Most inhabitants of wetlands avoid encounters with humans, but in the park, Ruddy Shelduck Tadorna ferruginea was not afraid of humans and begged for food. Visits to various biotopes and areas made it possible to supplement the list of birds in the park with encounters of new species such as the great Cormorant Phalacrocorax carbo, Green-winged Teal Anas crecca, Common Crane Grus grus, Coot Fulica atra, Lapwing Vanellus vanellus and Black-winged Stilt Himantopus himantopus, and confirm the nesting of Bittern Botaurus stellaris and Moorhen Gallinula chloropus. Nesting of coot and lapwing was recorded for the first time in the mountains of the Northern Tien Shan. In places where tourists are concentrated and live in campsites and yurts, the number of Black Kites Milvus migrans, Rock Dove Columba livia, Common Mynahs Acridotheres tristis, Magpies Pica pica and Carrion crows Corvus corone has increased. Of the species included in the Red Book of Kazakhstan, the Common Crane Grus grus, the Short-toed Eagle Circaetus gallicus and the Booted Eagle Hieraaetus pennatus are recorded.
