We simulated nests constructed in an area heavily used by ovipositing Diamond-backed Terrapins (Malaclemys terrapin) and foraging raccoons (Procyon lotor), to investigate the cues used by raccoons to locate terrapin nests. Marking nests with flags did not increase predation rates, and human scent decreased predation rates. Raccoons seemed to locate nests based on soil disturbance, ocean-water scent, or a combination of these cues.
