The Status of the Bald Eagle in Florida 1972-1975

During a three year study 282 successful nesting pairs of southern bald eagles (Haliaeetus leucocephalus leucocephalus) produced 404 young at a rate 0£1.43 young per successful nest, and 0.82 per active territory. This is similar to productivity report by Spruntet al (1973) for a 12 year study of eagles nesting in the Everglades. Production of young per active territory in the South Florida Region (report by Spruntet all973) was 0.73, for this survey it was 0.65. Statewide eagles used pine (Pinus sp) as nesting sites (60.5 percent), over cypress (Taxodium sp) (14.3 percent), and red, white, and black mangrove (Rhizophora mangle, Laguncularia racemosa, and Avicennia genninans) (22.9 percent). During the three seasons studied, eagles nesting in the Central Florida Region produced a total of 221 young (54.7 percent of statewide production) at a rate of1.47 young per successful nest. Eagles nesting in the South Florida Region produced 105 young(26.0 percent of the statewide production) at a rate of 1.44 younger successful nest and birds nesting in the North Florida Region produced 78 young (19.3 percent of the statewide total) at a rate of 1.32 young per successful nest.
