In 1986, it was estimated that the Eastern Bluebird population had declined 90% in its historic range during the previous 50 years. Loss of nesting habitat, predation from House Sparrows, European Starlings, Raccoons and the loss of nesting sites contributed to their decline. Private citizens, along with the Wisconsin Dept. of Natural Resources organized a non-profit organization, named BRAW, to try to reverse this trend. Wooden nest boxes were designed to attract cavity nesting birds, such as Bluebirds, Tree Swallows, Chickadees and House Wrens. The nest boxes were constructed and placed in likely nesting locations.
BRAW currently has over 900 members. About 20% of the members participate in a unique weekly monitoring of nest box activity. The information is summarized and reported annually to BRAW. Changes have been made to box design, spacing and location and recommendations to reduce predation. These changes have seen dramatic increases in Bluebirds numbers. Other cavity nesting birds have also seen increased numbers.
The quarterly newsletter “Wisconsin Bluebird” is sent to members who pay the annual membership fee. BRAW is a non-profit organization and is classified as a tax-exempt 501(c)(3) organization by the IRS. Membership fees and donations are tax deductible.

You are invited and welcome to tour nest boxes at Parnell Prairie Preserve. Open the box by removing the nail and see the activity. Replace the nail when you leave. The birds will return to their nest if not harassed or disturbed too much.
