We investigated nest-site characteristics and clutch success of hawksbill sea turtles (Eretmochelys imbricata) nesting on Shidvar Island, Hormozgan Province, in the Islamic Republic of Iran. We found that hawksbills tended to cluster their nests at a specific elevation above sea level, and that emergence success was highest in nests nearest to this preferred elevation, declining at higher and lower elevations. These results suggest that elevation might be an important cue for nest-site selection in this population.
