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.
