The results of bird route censuses, conducted on the territory of the Aldan Highland in the first half of summer and generally covering the period from 2000 to 2019, were analyzed. The total length of the routes was about 2815 km. A total of 116 initial variants of the bird population were used. Based on the results of multivariate factor analysis for 160 species registered in these censuses, a hierarchical classification of their preference for habitats was drawn up. The classification showed that 45 % of birds prefer forests, woodlands and burned areas, 26.2 % - water bodies and their banks, 13.8 % - bogs and meadows, 9.4 % - villages and cities, 5.6 % - mountain tundra. A comparative analysis with a similar classification for the Altai Highland has been performed. The main differences in the territorial distribution of bird species in the Aldan Highland and Altai lie in a smaller number of identified types of preferences in our region. Due to the homogeneity of forest biotopes and the absence of the steppe, forest-steppe, subnival, and nival zones in the Aldan Highland, the corresponding landscapes are not represented here, which determines the absence of the steppe, forest-meadow-steppe, meadow-bog, and subnival types. Similarly to Altai, the forest, tundra and synanthropic types of preference are distinguished in the Aldan Highland.
