Movements and Habitat Use By Hen Pheasants During Brood Rearing
… is pheasant habitat, and the production of pheasants is therefore greatly influenced by farming practices. Considerable research has been done on rates of pheasant production, nest success, and cover preferences for nesting. However, little information has been obtained on movements and …

Effects of Aldrin on Young Pheasants Under Semi-Natural Conditions
Effects of aldrin on young pheasants were studied under semi-natural conditions in four one-acre enclosures during the summer of 1968. The center two-thirds of each plot was planted in corn; remaining peripheral cover was maintained in smooth brome and alfalfa. Prior to planting, center portions of …

Use of Eelctrophoresis to Determine Populations of Pheasants in South Dakota
… has been transplanting or stocking wherein pheasants are introduced into an area with a depleted population in hopes of increasing pheasant production. The effects of such programs are difficult to evaluate since there is no way of knowing if the introduced birds are in any way responsible …

Seasonal Movements and Behavior of Ring-Necked Pheasants in Eastern South Dakota
… on mobility, behavior, and related activities of pheasants from July 1966 to July 1968 by banding and/or marking 160 birds with backtags and radio transmitters. Food was readily available since the winters were mild with little snow. Birds moved less than 1/4 mile from roosting areas to cornfields …

Effects of Dieldrin on the Social Interactions of Penned Pheasants and Chickens
… the effects of dieldrin on social hierarchy of pheasants and chickens were initiated in 1970. Social interactions were observed among groups of pheasant chicks, adult cock and hen pheasants and peck-order development among groups of young pheasants. To determine the effects of dieldrin on the …

Reproductive Ecology of Ring-Necked Pheasants in Central South Dakota's Winter Wheat Landscape
… wheat may be an alternate nesting habitat for pheasants. Winter wheat is predominately undisturbed throughout the pheasant’s nesting season, and undisturbed habitat provides an effective environment for nesting hens to avoid predators. The objectives of this study were to determine pheasant use …

Effects of Chick Stimuli and Dieldrin on Adoptive Behavior of Penned Hen Pheasants
… and dieldrin on adoptive behavior of penned hen pheasants were conducted in 1969 and 1970. Results indicated that whether caged hens saw or heard chicks had no effect on adoption or killing of chicks. Hens receiving sound stimuli and sight-and-sound stimuli from chicks responded similarly to hens …
