Breeding Bird Survey

In June 2003, a study was conducted on the breeding birds of the Sanctuary. The survey included 33 sites in various habitat types, distributed throughout the Ridges. A total of 63 bird species were observed. Some, such as Black-capped Chickadee and American Redstart, were found in many habitats and displayed no apparent preference for one habitat type over another. However, several species were found primarily in specific habitat types. These included some birds, such as Osprey and Yellow-bellied Flycatcher, which are listed as rare or of special concern in Wisconsin.
