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.

Migratory peregrine falcons, Falco peregrinus, accumulate pesticides in Latin America during winter Migratory peregrine falcons, Falco peregrinus, accumulate pesticides in Latin America during winter
Blood samples from 433 Peregrine Falcons (Falco peregrinus) during fall and spring migrations, 1976-80, indicated that most of their pesticide burden, primarily DDE, was accumulated on wintering grounds in Latin America. DDE in spring migrants returning from Latin America for the first time declined significantly from 1979 to 1980. Only about 10% of breeding-age females contained...

Organochlorine residues in bats after a forest spraying with DDT Organochlorine residues in bats after a forest spraying with DDT
Background levels of DDT and its metabolites (ZDDT) were extremely low or not detected in five species of forest-dwelling bats in northeastern Oregon, i.e., areas not sprayed with DDT in 1974. Other organochlorine pesticides were rarely found and no polychlotinated biphenyls (PCBs) were detected at any time during the study. Four of five species of bats showed significant changes in Z...

DDE not implicated in cliff swallow, Petrochelidon pyrrhonota, mortality during severe spring weather in Oregon DDE not implicated in cliff swallow, Petrochelidon pyrrhonota, mortality during severe spring weather in Oregon
Large numbers ofCliff Swallows (Petrochelidon pyrrhonota) died in late May near Burns, Oregon, during cold, wet weather. The brains of five dead birds did not contain lethal concentrations of DDE, and no PCBs were detected.

Decline and present status of breeding Peregrine Falcons in Oregon Decline and present status of breeding Peregrine Falcons in Oregon
Unprecedented declines of the Peregrine Falcon (Falco peregrinus) throughout much of the Northern Hemisphere became apparent during the Madison Peregrine Falcon Conference in 1965 (Hickey 1969). Data from Britain were the most detailed; broken or missing eggs were much more common in 1949-56 than they had been in earlier years (Ratcliffe 1958). Subsequently, Ratcliffe (1967) showed a...

Suspected Great Blue Heron population decline after a severe winter in the Columbia Basin Suspected Great Blue Heron population decline after a severe winter in the Columbia Basin
The wintering range of the Great Blue Heron (Ardea herodias) extends further north than does that of any other member of the Ciconiiformes in North America. The northern limits of its range extend along the Pacific coast into southeastern Alaska, into Massachusetts on the Atlantic coast, and inland into southern Montana (Palmer 1962). In the northern part of its range, severe winter...
