Breeding Bird Utilization Of Shelterwood-Cut Oak Stands In Buckingham County, Virginia, Kim Marie Mcdonald
Breeding Bird Utilization Of Shelterwood-Cut Oak Stands In Buckingham County, Virginia, Kim Marie Mcdonald
Theses & Honors Papers
Breeding bird populations on three shelterwood cut oak stands in Buckingham County, Virginia were studied using Breeding Bird Census (BBC) techniques. The stands were cut partly or entirely during the year prior to the 1997 breeding season, when the BBCs were conducted. The plots were established as part of a study of oak regeneration following controlled bums in the Virginia piedmont. Canopy cover on the plots averaged 66.8% after the cuts and total basal area averaged 41915 cm2/acre. At least 23 species of birds had territories partly or entirely on at least one of the plots, and at least nine …

Establishment Of A Nighthawk Migration Monitoring Program, Jeri Paige Guilliams
Theses & Honors Papers
The Nighthawk Migration Monitoring Program was initiated in 1997 to study the Common Nighthawk, Chordeiles minor. Modeled after the Hawk Migration Association of North America's hawkwatching methodology, the program enlisted volunteers to record time of day for peak flight, time of season for peak flight, weather conditions affecting migration, and other data. Volunteers were enlisted by establishment of a web page and e-mail address, preparation and circulation of a brochure, and through mail.
Individual chapters of the Virginia Society of Ornithology and others expressing interest were sent a letter, brochure, a Nighthawk Count Report Form, and an instruction sheet for …
The Effect Of Wildlife Management Techniques On Grassland Birds In Central Virginia, Eric Wayne Rosenbaum
The Effect Of Wildlife Management Techniques On Grassland Birds In Central Virginia, Eric Wayne Rosenbaum
Theses & Honors Papers
The purpose of this study was to examine the effects of wildlife management techniques on grassland bird species . Grassland birds have been declining in number for the last twenty-five years (Kershner and Bollinger 1996). Their decline is attributed to overall habitat loss. This study was conducted at James River Wildlife Management Area in Nelson County, Virginia. Three grassland plots were selected to represent three different kinds of management. One plot was planted in wheat, another in corn, and one plot was burned. Birds within these plots were monitored for one year. Each plot was also subjected to a vegetational …
