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.
Introduction:
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.
