The black noddy (Anous minutus), also known as white-capped noddy, is a species of tern in the family Laridae. It is a medium-sized seabird with black plumage and a white cap that closely resembles the lesser noddy with which it was at one time considered conspecific. The black noddy has slightly darker plumage and dark rather than pale lores.

Taxonomy

The black noddy was first formally described by German naturalist and lawyer Friedrich Boie in 1844 under its current binomial name.{{ cite journal | last=Boie| first=Friedrich | author-link=Friedrich Boie | year=1844 | title=Nuszüge aus dem Cystem der Ornithologie | journal=Isis von Oken | volume=1844 | at=Column 188 | url=https://www.biodiversitylibrary.org/page/13235792 | language=de, la }} The genus name Anous is ancient Greek for "stupid" or "foolish". The specific name minutus is the Latin for "small".{{cite book | last=Jobling | first=James A. | year=2010| title= The Helm Dictionary of Scientific Bird Names | url=https://archive.org/details/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling | publisher=Christopher Helm | location=London | isbn= 978-1-4081-2501-4 | pages=[https://archive.org/details/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling/page/n48 48], 256 }}

Behaviour

These birds may have become known as "noddies" because of the behaviour of both sexes as they constantly dip their heads during their breeding display. They are very tolerant of humans even to the extent that they can be picked up off the nest. They feed on fish and squid which they gather by flying low over the surface of the sea and picking them up. They may associate with other seabirds in areas where predatory fish are driving small fish to the surface.

The nests of these birds consist of a level platform, often created in the branches of trees by a series of dried leaves covered with bird droppings. One egg is laid each season, and nests are re-used in subsequent years. The trees used for this purpose are various but the Pisonia is most often used, and in large trees, there are often several nests.{{cite journal |author1=Barnes, A. |author2=Hill, G. J.

Distribution

The black noddy has a worldwide distribution in tropical and subtropical seas, with colonies widespread in the Pacific Ocean and more scattered across the Caribbean, central Atlantic and in the northeast Indian Ocean. At sea it is usually seen close to its breeding colonies within 80 km of shore. Birds return to their colonies, or to other islands, to roost at night.
