starts withThe Bonin nankeen night heron was described by Nicholas Aylward Vigors in 1839 based on reports by Heinrich von Kittlitz and by Captain Frederick William Beechey from the British ship HMS Blossom from 1828. It reached a size of about 61 cm. The crown was black and had two white ornamental plumes which reached to its back. The back was cinnamon-brown. The underparts were white. Feet and legs were orange and the bill was black. In contrast to the nankeen night heron it had a thicker and straighter bill.
It was only found on the Bonin Islands, Chichi-jima and Nakōdo-jima. Its habitat consisted of beaches and marshes where it nested in low trees.
