- Title
Frequency distribution of minimum distances between singing males in different chaffinch ( Fringilla coelebs L.) populations as an indicator of habitat quality.

Cherenkov, S. E.
- Abstract
The results of census mapping over nine nesting seasons have been used to calculate frequency distributions of minimum distances between male singing chaffinches. Comparison of these distributions shows consistent, high, and significant similarity of spatial structures within each population, despite considerable fluctuations in bird density (from 204 to 118 territories per hectare) and basic differences between spatial structures of different populations (two significantly different classes are distinguished). An approach to estimation of habitat quality by assessing the spatial structure of populations is proposed.
