Spatial Bird Distribution in North Urals in First Half of Summer

Results of route counts of the birds spent in territory of North Urals Mountains in first half of summer (1.06–15.07) and, in whole, are analyzed, covering the period with 1966 for 2005. Total extent of routes has made about 3000 km. In total 126 initial variants of the bird communities are used. By results of the multidimensional factorial analysis for 154 registered species features of their spatial preference are revealed and hierarchical classification is made. Comparisons to similar classifications by another regions are spent. Classification showed that 3% of the birds of this Ural provinces prefer the mountain tundra, 49% from it’s, mostly live in forests, 18% of the birds gravitate to the urbanized territories and 31% is a species of wetland ecosystems. A comparative analysis with similar classifications in other regions revealed the following. Due to the lack of extensive open agricultural landscapes in the Northern Urals, in contrast to the Medium, not the complex species, water and wetlands group, on the contrary, a lot more. By the nature of the distribution of bird species North Ural significantly differs from the average and, in General, the closer to the Altai provinces, among which are especially close to the forest of them — the North-East province.
