Seasonal carcass composition and energy balance of female black ducks in Maine Seasonal carcass composition and energy balance of female black ducks in Maine
Female Black Ducks (Anas rubripes) collected in Maine during the summer, fall, and winter of 1974-1976 showed significant seasonal variation in body weight, nonfat dry weight, gizzard and pectoral muscle weight, and fat, moisture, and protein content. Variation of body weight within and among seasons was correlated more strongly with carcass protein content, and with fat content during...

Breeding habitat selection and home range of radio-marked black ducks (Anas rubripes) in Maine Breeding habitat selection and home range of radio-marked black ducks (Anas rubripes) in Maine
Telemetry techniques were used to monitor the movements and habitat use of 13 female and 7 male black ducks (Anas rubripes) in an inland breeding region of south central Maine in 1977–1980. Black ducks preferred persistent emergent, broad-leaved deciduous forested, and broad-leaved deciduous scrub–shrub wetlands over unconsolidated organic bottom, needle-leaved evergreen forested, and...

Oviposition and the plasma concentrations of LH, progesterone, and corticosterone in bobwhite quail (Colinus virginianus) fed parathion Oviposition and the plasma concentrations of LH, progesterone, and corticosterone in bobwhite quail (Colinus virginianus) fed parathion
Bobwhite quail were fed concentrations of parathion (0,50, 100, 200 or 400 p.p.m.) for 10 days. Food intake, body weight change, brain acetylcholinesterase activity, egg production, and ovary weight were reduced in a dose-dependent manner. In a second experiment, birds were fed 0, 25 or 100 p.p.m. parathion or pair-fed control food to equate consumption in the 100 p.p.m. group. Egg...

Capturing birds with mist nets: A review Capturing birds with mist nets: A review
Herein we have tried to provide a comprehensive review of mist-netting techniques suitable for both novice and experienced netters. General mist-netting procedures and modifications developed by netters for particular bird species and habitats are included. Factors which influence capture success, including site selection, net specifications and placement, weather, and time of day, are...

Food habits of diving ducks in the Carolinas Food habits of diving ducks in the Carolinas
Food habits analyses were conducted on 264 diving ducks (7 species) from North and South Carolina during the 1970'S. The Baltic clam (Macoma balthica) was the predominant food among canvasbacks (Aythya valisineria) from the Pamlico River area, whereas sago pondweed (Potamogeton pectinatus) predominated in birds from impoundments in North and South Carolina. Shoalgrass (Halodule...

Pharmacokinetics and tissue concentrations of tylosin in selected avian species Pharmacokinetics and tissue concentrations of tylosin in selected avian species
Tissue and plasma concentrations and the biological half-life of tylosin in avian species of a variety of body sizes and metabolic rates were studied. The species chosen were eastern bobwhite quail (Colinus virginianus virginianus), pigeons (Columba livia), greater sandhill cranes (Grus canadensis tabida), and emus (Dromaius novaehollandiae). In the 1st phase of this study, tylosin was
