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.

Inheritance patterns of enzymes and serum proteins of mallard-black duck hybrids Inheritance patterns of enzymes and serum proteins of mallard-black duck hybrids
From 1974 to 1976, a breeding program was used to produce hybrids of black ducks and mallards for the evaluation of inheritance patterns of serum proteins and serum, liver and muscle enzymes. In addition to the crosses designed to produce hybrids, a series of matings in 1975 and 1976 were designed to evaluate inheritance patterns of a hybrid with either a black duck or mallard. At the F1...

Current impact of DDE on black-crowned night-herons in the intermountain west Current impact of DDE on black-crowned night-herons in the intermountain west
Organochlorine contamination was studied in eight black-crowned night-heron (Nycticorax nycticorax) populations nesting in Washington, Oregon, and Nevada in 1978-80. DDE was detected in 220 eggs sampled; eggshell thickness was negatively correlated with residues of DDE and polychlorinated biphenyls (PCB's). Other contaminants were detected in 35% or fewer of the eggs. Except for the two...

Age-specific productivity and nest site characteristics of Cooper's hawks (Accipiter cooperii) Age-specific productivity and nest site characteristics of Cooper's hawks (Accipiter cooperii)
Nesting Cooper's Hawks (Accipiter cooperii) were studied in northeastern Oregon. Second-year (SY) males did not breed, but 22 percent of the breeding females were SY's. Mean clutch size (P = 0.012) and mean number of young fledged per pair that laid eggs (P 0.10) were lower for SY females than for adult (after second year [ASY}) females; however, an equal percentage of the eggs...

Effects of heptachlor on American kestrels in the Columbia Basin, Oregon Effects of heptachlor on American kestrels in the Columbia Basin, Oregon
Wheat seeds treated with heptachlor to control wireworms (Ctenicara pruinina) resulted in American kestrels (Falco sparverius) in the Columbia Basin accumulating residues of heptachlor epoxide (HE) that reduced productivity and caused some adult mortality. The kestrel is more sensitive to HE residues in eggs than the Canada goose (Branta canadensis moffitti), i.e., reduced productivity...
