Breeding birds of the forested portions of Cedarburg Bog

Abstract

In 1971 the Wisconsin Scientific Areas Preservation Council inaugurated a program of annual breeding bird surveys in the various state scientific areas, carried out by members of the Wisconsin Society for Ornithology and coordinated by Mrs. Evelyn Warner. The object is to provide documented quantitative data for assessment of bird population trends, specifically as an index to possible environmental deterioration. The upland deciduous (maple-beech) woods at the UWM Field Station and a large part of the adjacent Cedarburg Bog are included in the scientific areas system, destined for preservation with minimal management for scientific research and education. As part of the program mentioned above I conducted breeding bird surveys in the bog in 1971, 1972 and 1973 and in the upland woods in 1971, while Dennis Gustafson conducted surveys in the upland woods in 1972 and 1973.
