Researchers look at possible causes of Chesapeake Bay pelican decline

Researchers are investigating why brown pelican breeding numbers have fallen in Chesapeake Bay. Maryland’s Department of Natural Resources counted about 575 breeding pairs this summer, most near Smith Island, while several previously active colonies were empty. Scientists say pelican populations are closely linked to menhaden availability, and warn that declining food supplies could affect other wildlife. They expect pelicans to remain in the Bay, though numbers may stay below levels seen a decade ago.
