Abstract
This article presents the results of bird ringing in the Western Tien Shan from 2001 to 2023. Methods for tagging and studying the migration routes, biology and ecology of birds are described, including catching and ringing, studying morphometric parameters, tagging with GPS/GSM transmitters, and visual surveys. Data are presented on the number of marked orders, species and individuals of birds for the specified period. In the period from 2001 to 2023, the most numerous species of birds were identified, as well as rare species that were able to be marked. The timing of autumn and spring migrations has been established, and the peaks and deadlines for bird migration have been identified. Some results of bird tagging with trackers are presented as well. This article also contains information about the meeting of ringed birds and the return of rings from different countries. Ecological and geographical connections of some bird species flying along the foothills of the Western Tien Shan have been established.
