The brown noddy or common noddy (Anous stolidus) is a seabird in the family Laridae. The brown noddy is a tropical seabird with a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean.

The black noddy or white-capped noddy (Anous minutus) is a seabird from the family Laridae . It is a medium-sized bird with black plumage and a white cap. It closely resembles the lesser noddy (Anous tenuirostris) with which it was at one time considered conspecific. The black noddy has slightly darker plumage and dark rather than pale lores.
