Join ornithologis Noah Perlut to learn about Bobolink and Savannah Sparrow movement ecology! Bobolink and Savannah Sparrow populations are declining throughout the Northeast. While intensifying grassland management and loss of breeding habitat are important factors in these declines, these birds spend ~9 months of the year away from the breeding grounds. We used miniaturized tracking devices to reveal mysteries of Bobolink and Savannah Sparrow movement ecology, connecting what happens to them on the breeding grounds to the rest of their life-cycle.
