Effects of egg oiling on larid productivity and population dynamics Effects of egg oiling on larid productivity and population dynamics
Small quantities of petroleum may adhere to the plumage, feet, or nest materials of breeding birds and be transferred to their eggs during incubation. In this study, oil was applied to naturally incubated Great Black-backed Gull (Larus marinus) and Herring Gull (L. argentatus) eggs, and its effects on reproductive success were assessed. Embryo survival was inversely proportional to the...

Toxicity of anticholinesterase insecticides to birds: Technical grade versus granular formulations Toxicity of anticholinesterase insecticides to birds: Technical grade versus granular formulations
The acute toxicities of 13 granular anticholinesterase insecticides were compared with their technical grade active ingredients by administering single oral doses of chemical to adult Northern bobwhites (Colinus virginianus) and evaluating resultant LD50 values and dose-response curves. Similar tests with ringed turtledoves (Streptopelia risoria) were conducted with five of the granular

Avian models for toxicity testing Avian models for toxicity testing
The use of birds as test models in experimental and environmental toxicology as related to health effects is reviewed, and an overview of descriptive tests routinely used in wildlife toxicology is provided. Toxicologic research on birds may be applicable to human health both directly by their use as models for mechanistic and descriptive studies and indirectly as monitors of...

High PCB residues in birds from the Sheboygan River, Wisconsin High PCB residues in birds from the Sheboygan River, Wisconsin
Organochlorine residues were measured in the carcasses and, in some cases, brains and stomach contents of four species of birds collected along the Sheboygan River, Wisconsin during the years 1976 to 1980. Polychlorinated biphenyls (PCBs) were high in all samples and were the contaminants of greatest concern. Carcass residues ranged from 23 to 218 ppm PCBs on a wet weight basis; these...
