Between 2011 and 2013 USGS researchers from Patuxent Wildlife Research Center sampled fish, osprey eggs, and osprey chicks' blood plasma at multiple sites in Chesapeake Bay to track the movement of certain pollutants through the Bay food chain. These hatchlings are just a few days old.

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.
