This project focused on evaluating the spatial relationships of migratory bird movements and how they are mediated by environmental factors, providing resource managers a tool for assessing effects of potential climate change and wind energy development on bird migration. The research has direct relevance to the management of protected areas, and he will work with cooperators to develop and deliver outreach materials and activities as a part of the project.  We analyzed the way the internal structure of abundance across breeding bird species ranges is reorganized over time. We tester how the internal dynamics - as measured by latitudinal shifts of populations - depends on the population's latitude and abundance, and the temperature dynamics of the site where the population is located. We found that the way abundance moves around a range is not random. We found that populations of high abundance and in the northern part of species ranges were the most dynamic
