Ko Lao Liang Phi (เหลาเหลียงพี่, หลาวเหลียงพี่) or Ko Lao Liang Tai (เหลาเหลียงใต้, หลาวเหลียงใต้), Amphoe Palian, Trang Province, Thailand. The island, part of Mu Ko Phetra Marine National Park, is a breeding ground of Swiftlets. It has been under concession for a very long time where island "owner" paid large sum of fee to government in exchange for the right to collect bird nests in the caves high up the hills. It was guarded with firearms and visiting the island was impossible until only recently (around 2003) where it is opened for tourism (for diving) during months with calm sea.
