Climate and Vegetation Hierarchically Structure Patterns of Songbird Distribution in the Canadian Boreal Region

Description: The authors evaluate how climate and vegetation contribute to boreal songbird habitat selection to better understand the factors that control boreal songbird distributions. Their analysis indicates that vegetation and climatic variables hierarchically structure songbird distribution in the Canadian boreal region, and suggests i) the importance of heterogeneity in vegetation for songbird distributions, and ii) a large potential for distribution shifts in response to climate change.
