Trends and effects of organochlorine residues on Oregon and Nevada wading birds, 1979-83
Charles J. Henny, L. J. Blus, C.S. Hulse
1985, Colonial Waterbirds (8) 117-128
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...
Pesticide and PCB residues in the Neuse River waterdog, Necturus lewisi
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....
Breeding chronology, molt, and measurements of accipiter hawks in northeastern Oregon
Charles J. Henny, R.A. Olson, T.L. Fleming
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...
Survival, growth, and histopathological effects of paraquat ingestion in nestling American kestrels (Falco sparverius)
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...

One-day old American Kestrel (Falco sparverius) nestlings were dosed orally daily with 5 ?l/g of corn oil (controls), 25 mg/kg, 125 mg/kg, or 625 mg/kg of metallic lead in corn oil through day 10. Forty percent of the nestlings given 625 mg/kg died after six days. Growth rates became significantly...

W. James Fleming, B. W. Cain
1985, Southwestern Naturalist (30) 269-277
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, J. C. Franson, Barnett A. Rattner
1985, Environmental Toxicology and Chemistry (4) 193-199
Diets mixed to contain 0, 0.1, 1.0, 10 and 100 ppm temephos (determined chemically to contain less than 0.5, less than 0.5, 0.89, 6.0 and 59 ppm temephos, respectively) in an Abate® 4E formulation, were fed to mallard (Anas platyrhynchos) ducklings for 7 d. During this period, half of the...
Lethal and behavioral effects of chlordimeform in bobwhite
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...

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...
Habitat comparisons and productivity in nesting common terns on the mid-Atlantic coast
R.M. Erwin, D. C. Smith
1985, Colonial Waterbirds (8) 155-165
Nesting Common Terns (Sterna hirundo) were studied at a number of barrier beaches and small islands of tidal salt marsh in New Jersey and the Eastern Shore of Maryland-Virginina from 1980 through 1982. Data were collected on clutch sizes, nest spacing, and nesting success. The principal null hypothesis tested was...

Thomas W. Custer, Elwood F. Hill, Harry M. Ohlendorf
1985, California Fish and Game (71) 220-224
Selected rice fields on the Sacramento National Wildlife Refuge Complex were aerially sprayed one time during May or June 1982 with either ethyl (0.11 kg Al/ha) or methyl (0.84 kg AI/ha) parathion for control of tadpole shrimp, Triops longicaudatus. No sick or dead vertebrate wildlife were found or adjacent to...

1985, North American Bird Bander (10) 56-57
This was my 4th year of banding in a powerline right-of-way that is specially managed to encourage growth of dense scrub. Nets were run for 2 to 3 hours each morning, because activity dropped off rapidly after the sun hit the nets. I banded on 79 days, from 1 August...
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...

1985, Colonial Waterbirds (8) 110-116
We collected eggs in nests, hatchlings and eggs with advanced embryos on the ground, and prefledgling young of Great Blue Herons (Ardea herodias) at three nesting colonies in Washington and Idaho. Intact fish were also collected on the ground at the Idaho colony. The Ft. Lewis colony near...

Wildlife in an oak forest on Blue Mountain was studied 10 km upwind (Bake Oven Knob site) and 2 km downwind (Palmerton site) of two zinc smelters in eastern Pennsylvania, USA. Previous studies at sites near these smelters had shown changes in populations of soil microflora, lichens, green plants and...
The effects of heptachlor and lindane on birds, Columbia Basin, Oregon and Washington, 1976-1981
L. J. Blus, Charles J. Henny, A. J. Krynitsky
1985, Science of the Total Environment (46) 73-81
The effects of heptachlor seed treatments on birds in the vicinity of the Umatilla National Wildlife Refuge, Oregon and Washington, were investigated from 1978 to 1981. An egg was collected from each of 60 nests representing six species. Heptachlor epoxide (HE) residues were detected in 35 eggs and were particularly...

L.A. Collum, T. H. Fritts
1985, Southwestern Naturalist (30) 101-104
The distribution of the sperm whale, Physeter catodon, was documented in the Gulf of Mexico during 1979 to 1981 using regular aerial surveys and opportunistic sightings from ships. Most sightings were in the western Gulf of Mexico in deep waters near the edge of the continental shelf. A total of...
Growth and blood chemistry of ducklings reared on acidified wetlands
Barnett A. Rattner, G. Haramis, G. Linder, D. Chu
1985, American Zoologist (25) 17A-17A
Acid deposition is one factor that may be responsible for the decline of some waterfowl populations. Growth and physiological condition were monitored in captive-reared black ducks (Anas rubripes) exposed for 10-day trials (day 11-20 of life) on control (pH 6.8) and acidified (pH 5.0) man-made emergent wetlands. Impaired...
Deposition of anal-sac secretions by captive wolves (Canis lupus)
C. S. Asa, E.K. Peterson, U.S. Seal, L.D. Mech
1985, Journal of Mammalogy (66) 89-93
Deposition of anal-sac secretions by captive wolves was investigated by a labelling technique using protein-bound iodine125 and food dye. Wolves deposited secretions on some but not all scats. Adult males, especially the alpha male, deposited anal-sac secretions more frequently while defecating than did females or juveniles. Secretions sometimes also were...
