Wildlife disease experts at the USGS National Wildlife Health Center in Madison, WI examine a double-crested cormorant while wearing full biosafety gear.  The postmortem examination, also known as a necropsy, gives the scientists clues to what may have caused the animal to die.  Examination of wild birds is important to detect pathogens that could imp

Alaska Native Science and Engineering Program (ANSEP) student Jakob Sipary holds a red-throated loon on the Canning River Delta, Alaska, July 2019 as part of a USGS study on loon marine habitat use areas. Jakob was an intern for the summer with the U.S. Geological Survey.
