Habitat and landcover associations for 143 landbird species.
Habitat specific densities
Using our national density models for Canada (version 4.0), we used a post-hoc stratification (‘post-stratification’) approach to estimate landcover based density estimates (males per ha) for each species and region (Canada and Bird Conservation Regions). We classified the predictive maps according to the 2005 MODIS-based North American landcover map into major land cover types (Conifer, Taiga Conifer, Deciduous, Mixedwood, Shrub, Grass, Arctic Shrub, Arctic Grass, Wetland, Cropland) and calculated the mean of the pixel level predicted densities. Uncertainty was based on the 5th and 95th percentiles of the bootstrap distribution.
