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.

Environmental contaminants, human disturbance and nesting of double-crested cormorants in northwestern Washington Environmental contaminants, human disturbance and nesting of double-crested cormorants in northwestern Washington

Double-crested Cormorants (Phalacrocorax auritus) in extreme northwestern Washington produced few young (0.27/occupied nest) in 1984; the clutch size was generally small and eggs, if laid at all, were laid later than usual. Residues (geometric means, wet weight) of DDE (0.58 and 0.59 ppm) in eggs from Colville Island and Protection Island were lower than from other locations in the...

Organochlorine residues in great blue herons from the northwestern United States Organochlorine residues in great blue herons from the northwestern United States

We collected eggs or young Great Blue Herons from eight nesting colonies in the northwestern United States from 1977 through 1982. Subadults were collected at three estuarine areas in Puget Sound in 1981 and dead young or adults were collected at various localities. Nearly all samples analyzed contained organochlorine residues. There was no evidence that nay of the organochlorines...
