The general characteristics of the plowing lands birds’ population during the breeding period in Upper part of Angara region
View through CrossRef
The results of birds investigations on the most disturbed agricultural territories (plowing lands) are represented for breeding period. General indicators characterized different birds populations of plowing lands are given (density of birds populations, number of species and list of species, leaded in population of each variant of plowing lands). It is determined, that birds populations of examined lands are differ significantly. The leaders in population for many birds populations are Passer montanus (Linnaeus, 1758), Alauda arvensis (Linnaeus, 1758), Corvus corone (Linnaeus, 1758), Anthus richardi (Vieillot, 1818). The birds populations are formed for a not long period, theirs structure is defined by plowing lands sizes and degree of mosaic and the character of neighboring territories.
