Survival, growth, and accumulation of ingested lead in nestling American kestrels (Falco sparverius) Survival, growth, and accumulation of ingested lead in nestling American kestrels (Falco sparverius)
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 different from controls in the 625 mg/kg group by day 3 and in the 125 mg/kg group by day 4...

Survival, growth, and histopathological effects of paraquat ingestion in nestling American kestrels (Falco sparverius) Survival, growth, and histopathological effects of paraquat ingestion in nestling American kestrels (Falco sparverius)
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 of paraquat dichloride (1, 1'-dimethyl-4,4'-bipyridinium) in...

Organophosphate insecticide (famphur) topically applied to cattle kills magpies and hawks Organophosphate insecticide (famphur) topically applied to cattle kills magpies and hawks
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 dead); mortality peaked between Day 5 and Day 13. Estimates of...

Trends and effects of organochlorine residues on Oregon and Nevada wading birds, 1979-83 Trends and effects of organochlorine residues on Oregon and Nevada wading birds, 1979-83
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 Night-Herons and showed...

Lethal and behavioral effects of chlordimeform in bobwhite Lethal and behavioral effects of chlordimeform in bobwhite
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 light beam interruptions in an open-field test at 8 days of age than bobwhite fed 0, 1...

Organochlorine concentrations in prefledging common terns at three Rhode Island colonies Organochlorine concentrations in prefledging common terns at three Rhode Island colonies
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 = 0.24 and 2.8 ppm...

Metal contamination in wildlife living near two zinc smelters Metal contamination in wildlife living near two zinc smelters
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 litter-inhabiting arthropods. The 02 soil litter horizon at Palmerton was heavily...
