Structure of Colonies and Nesting Peculiarities of Common Starling (Sturnus vulgaris) and Tree Sparrow (Passer montanus) in Green Zone of Engels City

We researched the nesting habits of the common starling and the tree sparrow in a woodland of Engels city altered by humans, the Saratov region. Birds’ selectivity in the choice of nesting holes was found. The way birds use nesting trees in different vital condition was researched. The estimation of spatial distribution of nests was made by the method called “the nearest neighbor”.
