Black noddy

The black noddy , 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. The black noddy was first formally described by German naturalist and lawyer Friedrich Boie in 1844 under its current binomial name. The genus name Anous is ancient Greek for "stupid" or "foolish". The specific name minutus is the Latin for "small".
