Martell, M., P. Redig, and G. Buhl. 1988-1989. A study on wintering and released rehabilitated bald eagles in Minnesota. Report submitted to the Nongame Wildlife Program, Minnesota Department of Natural Resources. 34 pp.
This project summarizes the second field season of a three year project documenting the survival and movements of released rehabilitated Bald Eagles, and the numbers, habitat use and contaminant levels of Bald Eagles wintering in Minnesota. A summary of the first years work was prepared by Martell and Redig (1988).
Objectives of this study included:
- Document the reintegration of Bald Eagles rehabilitated at TRC into the wild population.
- Determine the number of Bald Eagles using the Mississippi and St. Croix Rivers between October and April.
- Locate and document the use of Bald Eagle roost and feeding sites located between the Twin Cities and Lake Pepin.
- Determine the home ranges and use of roosts and feeding areas for individual eagles during the winter months.
- Determine contaminant levels in a sample of Minnesota wintering Bald Eagles.
