Taxonomy
The first formal description of the brown noddy was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Sterna stolida.[3] The genus Anous was introduced by the English naturalist James Francis Stephens in 1826.[4] The genus name Anous is Ancient Greek for "stupid" or "foolish". The specific name stolidus is Latin and also means "stupid" or "foolish".[5]
Four subspecies are recognised:[6]
- A. s. pileatus (Scopoli, 1786) – Red Sea, Indian Ocean east through the Pacific to Hawaii & Easter Island
- A. s. galapagensis Sharpe, 1879 – Galápagos Islands
- A. s. ridgwayi Anthony, 1898 – islands off western Mexico to Costa Rica
- A. s. stolidus (Linnaeus, 1758) – islands of the Caribbean and tropical Atlantic

Description
The brown noddy is 38–45 cm (15–18 in) in length with a wingspan of 75–86 cm (30–34 in). The plumage is a dark chocolate-brown with a pale-grey or white crown and forehead. It has a narrow incomplete white eye-ring.[7] The tail is long and wedge-shaped, and the feet and legs are dark.[8]
Behaviour
Breeding
The brown noddy is a colonial bird, usually nesting on cliffs, trees, or bushes. It occasionally lays its eggs on the bare ground. The nest itself is usually a
In their nuptial displays, the female and male bow and nod to each other. Courtship feeding and flights accompany this, in addition to the transfer of a small, freshly caught fish from the male to the female.[9]
This bird lays a clutch of one pink cream egg with lilac and chestnut maculation. The egg usually measures around 52 by 35 millimetres (2.0 by 1.4 in). This egg is incubated by both sexes for 33 to 36 days, with each parent incubating for one or two days while their mate is feeding at sea. After the chick hatches, it grows quickly; usually reaching the weight of the parents in three weeks.[9] When it fledges, about six to seven weeks after hatching,[8] it can sometimes weigh more than the parents, although this weight is lost quickly once it starts to fly. At this point, the fledgling is starting to rely on its parents less and less as it learns how to provide for itself.[9]
