By the time a loggerhead comes to shore for the first time, she has spent about 30 years at sea. She excavates an egg chamber in the sand, deposits a clutch of approximately 100 to 120 eggs, and then covers the pit with sand before immediately returning to the dark ocean.

Like all sea turtles, loggerheads are easily disturbed by human activity and artificial lights when they come ashore to nest. Eggs face a number of risks. Nests may be flooded by tides on low-lying and eroding beaches, which can cause heavy mortality.
