Ospreys are a top fish-eating predator in the Chesapeake Bay and a sentinel species of environmental health. By studying their diet and behavior, scientists can learn more about the effects of chemical contaminants on the Bay ecosystem. Scientist Rebecca Lazarus with the U.S. Geological Survey (USGS) Patuxent Wildlife Research Center takes us to Poplar Island, Maryland, to show us how she conducts contamination studies on the local osprey population and to explain why the bird is so important to researchers.

One of the most widespread birds on earth, ospreys can be found on every continent except for Antarctica. The Bay has one of the largest breeding populations of osprey in the world, and is home to the “fish hawk” from spring through late summer.
