Short-term effects of oil ingestion on American kestrels (Falco sparverius) Short-term effects of oil ingestion on American kestrels (Falco sparverius)
The Mexican Ixtoc oil well blowout resulted in extensive oil contamination along the Texas Gulf coast. This oil posed a potential hazard to migrating birds including the endangered peregrine falcon (Falco peregrinus). Laboratory tests with the American kestrel (Falco sparverius) indicated that the oil: water mixture gathered at the surface of the blowout site posed little acute hazard to...

Anarbylus switaki Murphy: An addition to the herpetofauna of the United States with comments on relationships with Coleonyx Anarbylus switaki Murphy: An addition to the herpetofauna of the United States with comments on relationships with Coleonyx
Anarbys switaki, a species previously known only from Baja California Sur, Mexico, occurs in eastern San Diego and southwestern Imperial Counties in California. In California, specimens tend to have continuous transverse bars on the body, are lighter in color, and more slender in body form than in southern Baja California. California populations appear to be confined to extremely rocky...

Enzyme activities in plasma, liver, and kidney of black ducks and mallards Enzyme activities in plasma, liver, and kidney of black ducks and mallards
Activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine phosphokinase (CPK), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) were measured in plasma, liver, and kidney, and gamma-glutamyl transferase (GGT) was measured in liver and kidney of black ducks (Anas rubripes). Activities of ALT, AST, GGT, and ornithine carbamyl transferase (OCT) were...

Migratory peregrine falcons, Falco peregrinus, accumulate pesticides in Latin America during winter Migratory peregrine falcons, Falco peregrinus, accumulate pesticides in Latin America during winter
Blood samples from 433 Peregrine Falcons (Falco peregrinus) during fall and spring migrations, 1976-80, indicated that most of their pesticide burden, primarily DDE, was accumulated on wintering grounds in Latin America. DDE in spring migrants returning from Latin America for the first time declined significantly from 1979 to 1980. Only about 10% of breeding-age females contained...

DDE not implicated in cliff swallow, Petrochelidon pyrrhonota, mortality during severe spring weather in Oregon DDE not implicated in cliff swallow, Petrochelidon pyrrhonota, mortality during severe spring weather in Oregon
Large numbers ofCliff Swallows (Petrochelidon pyrrhonota) died in late May near Burns, Oregon, during cold, wet weather. The brains of five dead birds did not contain lethal concentrations of DDE, and no PCBs were detected.

Hormonal treatment and flight feather molt in immature Sandhill Cranes Hormonal treatment and flight feather molt in immature Sandhill Cranes
Molt, the production of a new generation of feathers, is a poorly understood physiological phenomenon in nondomestic birds. Often in large birds like geese, flight is restricted by clipping the primary remiges on 1 wing and flight is restored after the molt when the primaries are replaced. A similar technique would be desirable for use with cranes conditioned for release to the native...

Subacute toxicity testing with young birds: Response in relation to age and intertest variability of LC50 estimates Subacute toxicity testing with young birds: Response in relation to age and intertest variability of LC50 estimates
The variability in toxic response of Japanese quail (Coturnix coturnix japonica) to a standardized 5-day subacute feeding trial was studied while age was increased at weekly intervals from 1 to 21 days and at different times with 14-day-old birds. The objectives were to identify the strengths and limitations of this subacute toxicity protocol and to provide possible explanations for...
