Geography

The highest point on the island (and the Muko-jima Group) is Mount Byōbu (屏風山), at 154.9 metres (508 ft).[2][5]

Natural history

The island is a breeding ground for the brown booby (Sula leucogaster) and black-footed albatross (Phoebastria nigripes).[6] Vegetation, including Pandanus boninensis, Lobelia boninensis, and Cirsium boninense, has been recovering since the eradication of goats introduced when the island was inhabited between the 1880s and 1944, and feral once the island was again uninhabited.[2][6][7][8]
