About this project in BBA Explorer
David Morton of the Virginia DGIF kindly sent us a copy of the atlas data set as an access database in May 2007.
Results should be cited as:
Breeding Bird Atlas Explorer (online resource). 2024. U.S. Geological Survey Patuxent Wildlife Research Center. <Date of access>. Data extracted from: Trollinger, Jeffrey B. and Karen K. Reay, 2001. Breeding Bird Atlas of Virginia 1985-1989, Virginia Department of Game and Inland Fisheries, Richmond, Virginia, 219 pages.

This publication was made possible by Virginia taxpayers that donated a portion of their state income tax refund to the Department of Game and Inland Fisheries Nongame and Endangered Wildlife Program.

Treatment of the received dataset

We imported the received dataset with modifications as follows to better combine with other atlases or to match publication cited above:

  • Chose not to include Merlin, Gray-cheeked Thrush and Snowy Owl based on normal distribution. Also not including 7 species that were observed only and show no breeding evidence. Several raptor sightings were downgraded to OB:RC, observed, raptor carrying food, based on the dataset received and confirmation from Dave Morton. The breeding codes CY, PA, CP, CE, BP, and BE included no description and were mapped as CO,CN or confirmed, adults carrying nesting material.
