Toxicity of chlorinated insecticides to quail and pheasants
J.B. DeWitt
1956, Atlantic Naturalist (11) 115-118
'Residues from insecticidal applications of chlorinated hydrocarbons may remain toxic for extended periods. In experiments designed to furnish information on the effects upon quail and pheasants of prolonged feeding upon diets containing small percentages of these compounds, it was shown that aldrin, dieldrin and endrin are cumulative, and that quail...

1956, American Journal of Veterinary Research (17) 144-148
1) Two strains of distemper virus have been isolated from wild raccoons and one strain from ferrets. 2) All strains isolated have induced bilirubinemia in raccoons and ferrets. Many raccoons with bilirubinemia also had jaundice. 3) Identification of these strains as members of the canine distemper virus complex...

Quantitative report of tests. 'Inclusion of 1 p.p.m, of aldrin, dieldrin, or endrin in diets fed growing quail resulted in high mortality rates, but the birds survived on diets containing 100 p.p.m, of DDT or 50 p.p.m. of strobane. Young pheasants survived on diets containing 50 p.p.m, of DDT...

Summary and Recommendations: We suggest that managers are approaching the limits of their ability to improve waterfowl harvest management, primarily because the information needed to make better decisions is being sacrificed by the current approach to setting regulations. We propose an actively adaptive management strategy in which regulatory...

Ecological study of ruffed grouse broods in Virginia

1956, The Auk (73) 33-41
The Ruffed Grouse (Bonasa umbellus), commonly called "pheasant" throughout the southern Appalachian region, is a popular game bird in the mountains of Virginia. Unfortunately, however, the grouse populations in this State have declined noticeably during the past fifty years. Because of this, special field studies were designed through the cooperation...
