Abstract
I conducted spring migration point counts and vegetation surveys at 29 forest patches in the Chicago, IL metropolitan area in 2012 and 2013. The forest patch selection was designed to test the effects of patch size, distance from the Lake Michigan shoreline and degree of urbanization. I conducted exploratory analysis to search for potential relationships. Vegetation structure variables, especially understory and subcanopy composition, were important factors for many models. Bird species determined to be area sensitive in previous studies were associated with large patches during migration. While path size, distance from the shoreline and urbanization were not frequently selected for models of the entire avian community, they were important in most models of individual species. No single combination benefitted all species, indicating that maintaining a variety of conditions in the region will support a diverse avifauna.
