Conservation status
Conservation
- NOAA Fisheries and our partners are dedicated to conserving and recovering turtle populations worldwide. We use a variety of innovative techniques to study, protect, and recover these endangered animals. We engage our partners as we develop regulations and recovery plans that foster the conservation and recovery of hawksbills and their habitats. The main global threat to h…
Distribution and habitat
- Hawksbills usually nest in small numbers, and often on remote beaches, so it is difficult to estimate population trends. The largest populations of hawksbills are found in the Caribbean, the Republic of Seychelles, Indonesia, and Australia.
Distribution
- The most significant nesting within the United States happens in Puerto Rico and the U.S. Virgin Islands. Each year, about 500 to 1,000 hawksbill nests are laid on Mona Island, Puerto Rico and another 100 to 150 nests on Buck Island Reef National Monument off St. Croix. Nesting occurs to a lesser extent on other beaches in St. Croix and on islands such as St. John, St. Thomas, Cule…
Description
- Hawksbills get their name from their unique beak-like mouths. A hawksbills head comes to a point, and its lower jaw is V-shaped, giving it a hawk-like appearance.
