This survey is a formal report of sightings, population, and other information related to Raptors in the state of Iowa. This item was used as supporting documentation for the Iowa Ornithologists' Union Quarterly field report of Winter 1976-1977.
The research notes cover the development and progress of the Breeding Bird Atlas project through 1988. The research notes include the number and type of species sighted in breeding blocks and two maps of Iowa showing the number of breeding blocks completed.
