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.

Filter Total Items: 198Fall migration routes, timing, and wintering sites of North American ospreys as determined by satellite telemetry
Satellite telemetry was used to determine fall migratory movements of Ospreys (Pandion haliaetus) breeding in the United States. Study areas were established along the lower Columbia River between Oregon and Washington; in north-central Minnesota; on Shelter Island, New York; and in southern New Jersey. Seventy-four adults (25 males, 49 females) were tracked from 1995 through 1999. Migration routeAuthorsM.S. Martell, Charles J. Henny, P. Nye, Matthew J. SolenskyDeclining ring-necked pheasants in the Klamath Basin, California: II. Survival, productivity, and cover
Cover condition and its influence on nesting success, survival, and body condition of ring-necked pheasants (Phasianus colchicus) were evaluated at Tule Lake National Wildlife Refuge (TLNWR) and Lower Klamath National Wildlife Refuge (LKNWR). Inadequate nesting cover was responsible for extremely low nest success early in the nesting season at TLNWR. Later in the season at TLNWR, spring-planted crAuthorsRobert A. Grove, D. R. Buhler, Charles J. Henny, A. D. DrewAssessment of biological effects of chlorinated hydrocarbons in osprey chicks
Osprey (Pandion haliaetus) eggs were collected during 1995 and 1996 at seven sites along the Fraser and Columbia River systems of British Columbia, Canada, and Washington and Oregon, USA. Fifty-four eggs were placed into a laboratory incubator. Thirty-eight of the hatched chicks were sacrificed within 24 h. Hatching success did not differ among sites and therefore between treatment and reference aAuthorsJ. E. Elliott, L. K. Wilson, Charles J. Henny, Suzanne F. Trudeau, Frederick A. Leighton, Sean W.

Eggs of ospreys (Pandion haliaetus) were collected over the period 1991 to 1997 at 111 nests in the Fraser and Columbia River drainage systems of British Columbia, Washington, and Oregon. Contents were analyzed for organochlorine (OC) pesticides, polychlorinated biphenyls (PCBs), and total mercury.

HennyField evaluation of lead effects on Canada geese and mallards in the Coeur d'Alene River Basin, Idaho
Hatch year (HY) mallards (Anas platyrhynchos) in the Coeur d'Alene (CDA) River Basin had higher concentrations of lead in their blood than HY Western Canada geese (Branta canadensis moffitti) (geometric means 0.98 versus 0.28 μg/g, wet weight). The pattern for adults of both species was similar, although geometric means (1.77 versus 0.41 μg/g) were higher than in HY birds. HY mallards captured inAuthorsCharles J. Henny, L. J. Blus, D. J.

Since 1995 we have trapped and tagged 110 Ospreys (Pandion haliaetus) from 12 study sites in 8 states (Fig. 1). This total includes 71 females, 32 males and 7 juveniles. Our study areas encompass the major Osprey population concentrations found in the United States including the Western States, the Great Lakes region and the Eastern Seaboard.Tagging of nesting pairs along with three complete familAuthorsMark S.

Butyltin compounds, including mono-, di-, and tributyltin (MBT, DBT, and TBT) were measured in livers of 40 adult river otters (Lutra canadensis) collected from rivers and coastal bays in Washington and Oregon, USA. Butyltins were found in all the river otters, at a concentration range of 8.5–2,610 ng/g, WW. The greatest concentration of total butyltins of 2,610 ng/g, WW, was found in a river otteAuthorsK.

GeisyPersistence of high lead concentrations and associated effects in Tundra Swans captured near a mining and smelting complex in northern Idaho
Lead poisoning of waterfowl, particularly tundra swans (Cygnus columbianus), has been documented in the Coeur d'Alene River Basin in northern Idaho for nearly a century. Over 90% of the lead-poisoned tundra swans in this area that were necropsied have no ingested lead shot. Spent lead shot from hunting activities over the years is therefore a minor source of lead in these swans. The migrating swanAuthorsL. J. Blus, C. J. Henny, D. J. Hoffman, L. Sileo, D. J.

We investigated chlorinated hydrocarbon contaminants in aquatic mustelid species on the Fraser and Columbia Rivers of northwestern North America. Carcasses of river otter (Lutra canadensis) (N=24) and mink (Mustela vison) (N=34) were obtained from commercial trappers during the winters of 1990–91 and 1991–92.

NorstromSodium cyanide hazards to fish and other wildlife from gold mining operations
Highly toxic sodium cyanide (NaCN) is used increasingly by the international mining community to extract gold and other precious metals through milling of high grade ores and heap leaching of low grade ores. Of the 98 million kg cyanide (CN) consumed in North America in 1989, about 80% was used in gold mining (Knudson 1990). In Canada, more than 90% of the mined gold is extracted from ores with thAuthorsR. Eisler, D. R. Clark, Stanley N. Wiemeyer, C. J. HennyNon-USGS Publications**
