Bald Eagle Nest Site Characteristics in South Florida
Curnutt JL and Robertson WB. 1994. Bald Eagle Nest Site Characteristics in South Florida. The Journal of Wildlife Management. 58(2):218-221
Florida had nearly 20% of the coterminous United States population of nesting bald eagles (Haliaeetus leucocephalus) in 1990 (U.S. Fish and Wildl. Serv. 1991), yet the nesting ecology of bald eagles in subtropical environments has not been investigated. We examined nest site selection (n = 156 sites) by bald eagles in Florida Bay, Florida, from 1959 to 1990. Black (Avicennia germinans) and red mangroves (Rhizophora mangle) were used as nest trees almost exclusively (96.9%), and more than half were snags. Eagles also built nests on the ground (n = 3) and raised young on the ground after nests collapsed (n = 5). Eagles preferred (P < 0.05) higher keys (grass, hardwood-buttonwood [Conocarpus erecta]) over low-lying keys (mangrove, marsh) for nesting. Management strategies should include the preservation of live and dead mangroves and large, undisturbed keys as potential nesting sites for bald eagles in the subtropical portion of the eagle's range.
