Detailed Description

USGS researcher Rebecca Lazarus prepares to take a blood sample from an osprey fledgling in a nest on the Chesapeake and Delaware Canal, Delaware Bay in 2015. Lazarus and colleagues did similar sampling of 48 chicks on Chesapeake Bay in 2011-2013. All the Chesapeake Bay nestlings’ blood plasma had traces of a human medication to fight hypertension, diltiazem, and biomarkers of low-grade genetic damage, with no discernible effects on the ospreys’ reproductive success.
