The main aim of this study was to determine the numbers, population structure and seasonal changes in group structure of argali Ovis ammon karelini Severtzov, 1873 in the Tian-Shan of Kyrgyzstan. The study was carried out within two adjoining areas: the Baralbas River region, and the Ak-Tash River region. Data were collected during three seasons: winter, spring and summer. This population consisted of 42.3% females, 22.2% males, 13.4% yearlings, and 22.1% lambs. Composition and numbers of groups were seasonally changing.
