Minnesota Breeding Bird Atlas

OBJECTIVE/PURPOSE OF PROJECT:

Minnesota is currently the only state along the Mississippi Flyway without a Breeding Bird Atlas. To fill this void, Minnesota Audubon is coordinating a five year effort to survey every township in the State, largely with the use of volunteers. The objective of the atlas project is to map the distribution and abundance of breeding birds in the state and to identify areas of high bird diversity. The Superior National Forest supports this effort and assists with surveys, especially in townships where volunteer participation is unlikely.

METHODS OR TECHNIQUES USED:

Beginning in 2009, volunteers in Minnesota began surveying the northeast quadrant of every township in the State (Priority Blocks). Participants select a Priority Block and survey the habitat types within that block during the breeding season, recording the breeding status of each species seen. To complete a block requires 5-6 visits between March-August for a total of about 20 hours of survey time. Forest Service biologists have adopted several priority blocks on the Superior National Forest. In addition, we provided support for a bird monitoring crew to survey priority blocks in the Boundary Water Canoe Area Wilderness. Two presentations were given to the general public to introduce the program and recruit bird suvey volunteers.

REALIZED/EXPECTED RESULTS:

Forest biologists conducted breeding bird atlas surveys in 11 priority blocks outside of the Boundary Water Canoe Area Wilderness. The bird monitoring crew completed 16 priority blocks in the Boundary Waters Canoe Area Wilderness. Although priority blocks are 3 miles by 3 miles; it is generally not possible to cover the entire block. We assume coverage of 640 acres per block for purposes of this report. Results can be viewed at mnbba.org.
