Abstract

This study was designed to test the reliability of avifauna information retrieved from Biota
of Virginia, BOVA, a computerized fish and wildlife information system developed at Virginia
Polytechnic Institute and State. University. Reliability was defined as the percent of species that were detected during field surveys that also were listed by BOVA to occur. Six habitat types were
selected for study within the Blacksburg Ranger District of the Jefferson National Forest in
Southwestern Virginia. These were Mixed (oak-pine) Seedling/Sapling, Mixed Pole, Mixed
Mature, Deciduous Pole, Deciduous Mature, and Coniferous Pole. Three stands of each type, each
8-20 hectares in area, were chosen randomly for study: Each stand was surveyed with 12 90-minute
survey periods over 2 years. The random-walk technique was used to determine species occurrence.
BOVA species lists were determined for comparison with lists of species detected in the field. All
species detected in the field and(or) listed by BOVA were placed into at least one status category
defined by BOVA (e.g., Federal Migratory, Game, Accidental) or the Virginia Society of
Ornithology (e.g., Abundant, Permanent Resident, Transient Breeder).
