Loggerheads nest the furthest north of all the sea turtles, as far as North Carolina.
All of the nesting sites are found either north of the Tropic of Cancer or south of the Tropic of Capricorn with exception of western Caribbean populations. Loggerheads used to nest on beaches from Virginia to the Gulf Coast, but habitat loss resulting from human development, restricted their nesting sites to the coast of Delaware, and such places as Costa Rica and Cuba. Mating occurs in surface waters offshore from the nesting beaches. In the spring and summer female loggerheads come ashore at night, in the flood of spring tides, to lay their eggs. The nest site she chooses is usually an undisturbed, well-drained dune or grassy area.
