abstract
The loggerhead sea turtle Caretta caretta is listed as threatened with extinction on the US Endangered Species Act. Those loggerhead turtles that nest on US beaches from North Carolina to north-east Florida are a genetically distinct subpopulation. This subpopulation is small, and may be declining. To obtain information about the migratory pathways of these turtles we tracked post-nesting movements of five females by satellite from their nesting beach at Wassaw Island, Georgia. Four turtles migrated north of the nesting beach, of which three moved to coastal waters of mid Atlantic states (total distances of 157-1,458 km). Efforts to reduce mortality of northern subpopulations of loggerhead turtles need to focus on identifying and reducing threats in north-east US waters. 2002 FFI.
