Abstract
The results of route bird registration carried out at the territory of the Ural mountainous land (from the Polar to South Urals inclusive) during the first half of summer (16.05-15.07) since 1948 to 2000 were analyzed. Total length of routes was about 3500 km. Total number of versions of bird population was 394. On the basis of results of multidimensional factor analysis, the features of spatial preference were revealed for 243 recorded species and the hierarchic classification was composed. Comparison with similar classifications for East European and West Siberian plains and Altai was carried out.
