Charles J. Henny
I am a Scientist Emeritus at the USGS Forest and Rangeland Ecosystem Science Center.
My research focuses on field studies of raptors and fish-eating birds, particularly Ospreys. I am interested in the unique situations and characteristics that make particular species vulnerable to contaminant threats. In my spare time I enjoy collecting bird books.
