Olive-sided Flycatchers (Contopus cooperi), Special Concern in Wisconsin, are uncommonly found in a variety of coniferous forests in northern Wisconsin, especially sparsely forested spruce-tamarack bogs and swamps with openings or meadows created by rivers or streams, or burns. During the breeding season, the species typically builds nests in trees where tall dead snags are present or at forest edges and openings. The recommended avoidance period is June 1 - August 1.
