Acute oral toxicity of sodium cyanide in birds Acute oral toxicity of sodium cyanide in birds
Sensitivities of six avian species, black vulture (Coragyps atratus), American kestrel (Falco sparverius), Japanese quail (Coturnix japonica), domestic chicken (Gallus domesticus), eastern screech-owl (Otus asio), and European starling (Sturnus vulgaris), to acute poisoning by sodium cyanide (NaCN) were compared by single dose LD50's. Three species, domestic chickens, black vultures, and...

Analysis of cyanide in whole blood of dosed cathartids Analysis of cyanide in whole blood of dosed cathartids
A gas-liquid chromatographic method was modified to quantify both unmetabolized (“free”) and metabolized (“bound”, i.e., thiocyanates) cyanides. The methods for both are efficient and sensitive to 0.05 ppm. Repeated freezing and thawing of whole blood from treated cathartids caused an initial increase in free cyanide concentrations, followed by a gradual decline to a plateau. Bound...

Organochlorine contaminants in passeriformes and other avian prey of the peregrine falcon in the western United States Organochlorine contaminants in passeriformes and other avian prey of the peregrine falcon in the western United States
About 1,150 individuals of 38 species of Passeriformes and other small birds were collected in 1980 at 36 locations in eight western U.S. states for organochlorine (OC) chemical analysis. The bird carcasses (less beak, tarsi, gastrointestinal tract, and feathers) were combined by species and location (4 to 15 specimens per sample) into 124 composited samples for analysis. Also analyzed...

DDE, DDT + dieldrin: Residues in American kestrels and relations to reproduction DDE, DDT + dieldrin: Residues in American kestrels and relations to reproduction
Captive American kestrels (Falco sparverius) given long-term dietary dosages of DDT and dieldrin in combination, at low and high rates, were compared with controls to determine the effects of the toxicants on reproductive success and eggshell thickness. Additional kestrels were dosed with DDE to determine its effect on shell thickness. Tissues of birds that died or were sacrificed, and...

Nesting of the masked booby on the Dry Tortugas, Florida: The first record for the contiguous United States Nesting of the masked booby on the Dry Tortugas, Florida: The first record for the contiguous United States
In both 1984 and 1985 Masked Boobies (Sula dactylatra) attempted to nest on sandy islets at the Dry Tortugas, Florida. Nesting attempts failed because the nest sites were washed away by summer storms. It seems likely that this species will eventually nest there successfully and will establish a small breeding population. This is the first documented nesting by this species in the...

Presence and effects of the dog louse Trichodectes canis (Mallophaga, Trichodectidae) on wolves and coyotes from Minnesota and Wisconsin Presence and effects of the dog louse Trichodectes canis (Mallophaga, Trichodectidae) on wolves and coyotes from Minnesota and Wisconsin
The dog louse was found on 19 wolves (Canis lupus) and six coyotes (C. latrans) from Minnesota and Wisconsin during the July-February, 1973 through 1983, period. No evidence was found that lice had any serious effect on wolf survival.
