Densities and Biomass Relationships of Birds Nesting in Boreal Forest Habitats
A spot-mapping technique was applied to obtain quantitative data on bird populations on 25-acre (10 hectare) plots in northern boreal forest habitats. The number of breeding passerines varied from 15 to 42 pairs per plot. The number of species varied from 6 to 11 breeding passerines and 4 to 8 non-p...
