The Hawaiian island sometimes called "Bird Island" is more commonly known as Nihoa. It is the tallest of the ten islands that make up Hawaii and is located at the southern end of the island chain. It is roughly 240 kilometers away from the main island, Kaua’i, and covers only 171 acres of land. Despite its small size, the island boasts an impressive array of both animal and plant species, and is the most diverse island. It became a wildlife reservation in 1909, and this is partly why it is known as Bird Island.
