R.J. Hall, R. M. Prouty, R.E. Ashton
1985, Brimleyana (10) 107-109
Residues of 6 organochlorine contaminants were found in N. lewisi from 6 sites in the Tar and Neuse river systems. Concentrations of pesticides were low and apparently related to geographic patterns of use. Levels of PCB were higher and did not seem to vary geographically....

1985, Journal of Field Ornithology (56) 97-112
Most northern goshawks completed laying eggs in April, while most Cooper's hawks completed their clutches in May with essentially no overlap. The sharp-shinned hawks laid in late May and June. Juvenile females represented 4% of the northern goshawk breeding population; 22% of the Cooper's hawk breeding population (highest reported for...

D. J. Hoffman, J. C. Franson, O. H. Pattee, C.M. Bunck
1985, Archives of Environmental Contamination and Toxicology (14) 495-500
The use of paraquat as a herbicide is becoming more extensive with the increasing popularity of no tillage agriculture, increasing the possibility of exposure for wildlife species. American kestrel (Falco sparverius) nestlings were orally dosed daily with 5 ?l/g of distilled water (controls), 10 mg/kg, 25 mg/kg, or 60 mg/kg...

The incidence of DDT (parent compound) declined significantly in the eggs of Black-crowned Night-Herons (Nycticorax nycticorax), White-faced Ibis (Plegadis chihi), and Black-necked Stilts (Himantopus mexicanus), and showed a downward trend in Snowy Egrets (Egretta thula). Mean DDE residues (breakdown product of DDT) in eggs declined significantly in Black-crowned...

Charles J. Henny, L. J. Blus, E. J. Kolbe, R. E. Fitzner
1985, Journal of Wildlife Management (49) 648-658
A systematic field study of a black-billed magpie (Pica pica) population revealed that magpies and red-tailed hawks (Buteo jamaicensis) were killed by famphur (=famophos, Warbex®) used as a pouron to control cattle warbles (Hypoderma sp.). Magpie mortality began on treatment day and continued for more than 3 months (38 found...
Enzyme activities in plasma, kidney, liver, and muscle of five avian species
J. C. Franson, H. C. Murray, C. Bunck
1985, Journal of Wildlife Diseases (21) 33-39
Activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), creatine phosphokinase (CPK), and lactate dehydrogenase (LDH) were determined in plasma, kidney, liver, and muscle from five species of captive birds. Few differences occurred in plasma activities between sexes but considerable differences occurred between species. All five...

Can relocated wolves survive?
Steven H. Fritts, William J. Paul, L. David Mech
1985, Wildlife Society Bulletin (13) 459-463
Considerable interest has been expressed recently in establishing gray wolves (Canis lupus) into parts of their former range (Bailey 1978, Weaver 1978, Klinghammer 1979, Mech 1979, Henshaw 1982). However, the proper procedure for reintroductions is debatable (Klinghammer 1979). To date, wolf relocations have been conducted in Alaska, where 5 2-year-old...

1985, Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies (39) 337-343
Reproductive tracts from 89 3-year-old female river otters (Lutra canadensis), from Louisiana were examined. Eighteen of these were in a reproductive phase out of synchrony with the expected population norms. Eight of 32 otters had fewer embryos than corpora lutea, indicating intrauterine mortality in 25% of the sample. Chemical analyses...

Wings from mallard ducks harvested in 1980 in Arizona, Arkansas, Louisiana, and New Mexico were pooled into county aggregates and analyzed for organochlorine pesticides and PCB's. Organochlorine concentrations in duck wings were compared among counties comprising major river drainages within each state. DDE concentrations in the wings of mallards collected...

W. James Fleming, G. H. Heinz, C.A. Schuler
1985, Toxicology (36) 37-47
The 7-day LC50 of chlordimeform to bobwhite (Colinus virginianus) chicks was 2835 ppm (95% CI = 2169-3705 ppm). Bobwhite chicks fed 1000 ppm (~ LC4) chlordimeform for 7 days ate less, weighed less, travelled farther from a fright stimulus in an avoidance test, and had significantly more groups make >10...

Organochlorine concentrations in prefledging common terns at three Rhode Island colonies
T. W. Custer, C.M. Bunck, C. J. Stafford
1985, Colonial Waterbirds (8) 150-154
Concentrations of DDE, polychlorinated biphenyls (PCBs), and polychlorinated diphenyl ethers (PCDPEs) in carcasses of prefledging Common Terns (Sterna hirundo) at three Rhode Island colonies support the hypothesis that local contamination is responsible for among-colony differences observed in eggs in an earlier study. The highest concentrations of DDE and PCBs (mean...
