Chesapeake Bay ospreys are healthy despite toxics in their fish diet

Detailed Description

An adult osprey brings a fish to its nestlings at Poplar Island, Maryland. USGS researchers placed game cameras in some osprey nests to identify the types of fish that Chesapeake Bay ospreys are eating, then tested those fish species for toxic chemicals. They found the ospreys do bioaccumulate, or concentrate, some toxics from the fish they eat, but the fish hawks are successfully raising abundant numbers of chicks nonetheless.
