Bird Count Methods

  • We use standard ten minute, unlimited radius point counts to conduct our breeding bird surveys. Counts are conducted by trained observers.
  • Our monitoring program is more regionally intensive than the national Breeding Bird Survey (1200 points versus less than 100 routes in the forested region of northern Minnesota and Wisconsin).
  • Our points are placed in specific habitats so we can link population trends and bird occurrence to habitat.This allows us to get a better picture of population trends in specific forest areas.
  • We have taken the lead in developing a standard method for monitoring songbird populations in the Great Lakes region. With standard methods, results from the various monitoring programs can be combined and compared.
  • Breeding bird monitoring programs have been established for the Apostle Islands, Nicolet National Forest, Hiawatha National Forest, Ontario, Minnesota Department of Natural Resources, and United States Fish and Wildlife Service.
