    Breeding Birds of the Cornish Hardwood Management Area: Aitkin County, Minnesota 1998-2000
    (University of Minnesota Duluth, 2000) Hanowski, JoAnn M
    Breeding bird surveys were conducted for the third consecutive year in the Cornish Hardwood management area (CHMA), located in northeast Aitkin County. The objectives of this project are to: 1) establish a long-term breeding bird monitoring program in the CHMA to detect annual changes in species abundances, 2) determine whether bird community composition and species abundances are affected by uneven-aged management, and 3) compare the bird community in the CHMA with other northern hardwood stands in northern Minnesota. This report provides a summary of bird surveys completed in June of 2000 and also compares 1998, 1999 and 2000 survey results.
