White-tailed deer migration and its role in wolf predation White-tailed deer migration and its role in wolf predation
Seventeen white-tailed deer (Odocoileus virginianus) were radio-tagged in winter yards and tracked for up to 17 months each (881 locations) from January 1973 through August 1974 in the central Superior National Forest of NE Minnesota following a drastic decline in deer numbers. Ten vyolves (Canis lupus) from 7 packs in the same area were radiotracked before and/or during the same period...

Woodcock use of clearcut aspen areas in Wisconsin Woodcock use of clearcut aspen areas in Wisconsin
Clearcut areas in northern Wisconsin aspen (Populus spp., mostly P. tremuloides) forests were highly attractive to woodcock (Philohela minor) for feeding and night-roosting, and made excellent sites for woodcock trapping and banding. Woodcock use of clearcuts was extended for several years by annually removing vegetation from trails with a bulldozer. A continued high demand for aspen...

Preliminary assessment of aerial photography techniques for canvasback population analysis Preliminary assessment of aerial photography techniques for canvasback population analysis
Recent intensive research on the canvasback has focused attention on the need for more precise estimates of population parameters. During the 1972-75 period, various types of aerial photographing equipment were evaluated to determine the problems and potentials for employing these techniques in appraisals of canvasback populations. The equipment and procedures available for automated...

Comments on recent canvasback habitat trends and threats on Chesapeake Bay Comments on recent canvasback habitat trends and threats on Chesapeake Bay
During the last 22 years, the North American winter population of canvasbacks has fluctuated from 481,000 in 1955 to 179,000 in 1972. The Chesapeake Bay population has averaged 33 percent of the North American population and 64 percent of the Atlantic Flyway population. In Maryland, significant annual fluctuations have been recorded between the eastern and western shore of Chesapeake Bay...
