Changing food habits of bald eagles in Maine. Wheeler, B. Ph.D. Thesis, 2009.
abstract   bibtex   
This study marks the first analysis of bald eagle (Haliaeetus leucocephalus) diets in Maine since the population’s recovery. The remains of 125 prey individuals were collected from 22 distinct bald eagle nest territories on the Penobscot River in Maine, during the months of May and June between 2004-08. A total of 28 prey species were identified, of which 13 were bird, 8 fish and 7 mammal. A minimum of 125 individual food items were identified from 22 nest territories. Inland bald eagles were found to have increased their use of avian and mammalian prey since the comparison study (Todd et al. 1982) while decreasing in use of fish prey were found, raising concerns about seabird populations. The types of fish and mammal prey also shifted, suggesting bald eagles to be opportunistic foragers.
