Dua Island (Pulau Dua) is the name of a small nature preservation inhabited by some 50 kinds of fish-eating birds. It is located in the Banten bay and is accessible by boat from Tanjung Priok sea harbor or from Marina, Ancol.
This pristine island is also one of Indonesia's major bird sanctuaries, where more than 50,000 birds stop over during the winter or breeding season. Among these migratory creatures include egrets, ibis, teals, kingfishers and pelicans, while herons, storks and cormorants are some of the permanent residents. These birds originated from Africa, Asia and Australia and stay on this island to lay and hatch their eggs during April through August each year and fly back home afterwards. Little wonder, then, that this natural heaven is also known as Pulau Burung (Bird Island). The island is a hop away from Banten old town and can be accessed by walking on the shoal during low tide. The visitors can take a boat to get there quickly and safely.
