  • Birds Tell Us About Migration

    September 20, 2022 | Written by Renee Wilson of National Audubon Society
    Purple Martins (Progne subis) are long-distance migrants, with most wintering in the Amazon Basin after breeding across the eastern U.S. and Canada. Biologists at the University of Delaware are conducting a study to learn more about Purple Martins. Their goal? To link the movement ecology of individual birds in the mid-Atlantic region with their breeding productivity, foraging habitat use, survival, migration phenology, and nonbreeding locations. The study will also identify the locations and monitor the phenology of autumn Purple Martin roosts in the mid-Atlantic region.
