The '''brown noddy, common noddy''' or '''noddy tern''' ('''''Anous stolidus''''') is a seabird in the family Laridae. The largest of the noddies, it can be told from the closely related black noddy by its larger size and plumage, which is dark brown rather than black. 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 brown noddy is colonial, usually nesting on elevated situations on cliffs or in short trees or shrubs. It only occasionally nests on the ground. A single egg is laid by the female of a pair each breeding season. In India, the brown noddy is protected in the PM Sayeed Marine Birds Conservation Reserve.<ref>{{Cite news|url=https://scroll.in/article/961303/lakshadweep-gets-worlds-first-sea-cucumber-conservation-reserve-to-curb-smuggling-into-china|title=Lakshadweep gets world's first sea cucumber conservation reserve to curb smuggling into China|newspaper=Scroll|author=KA Shaji|date=13 May 2020|access-date=23 July 2020}}</ref>
==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''.<ref>{{cite book | last=Linnaeus | first=C. | author-link=Carl Linnaeus | year=1758 | title= Systema Naturæ per regna tria naturae, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis, Volume 1| volume=v.1 | edition=10th | page=137 | publisher=Holmiae:Laurentii Salvii | language=la | url=https://www.biodiversitylibrary.org/page/727042}}</ref> The genus ''Anous'' was introduced by the English naturalist James Francis Stephens in 1826.<ref>{{cite book|last1=Stephens|first1=James Francis|url=https://www.biodiversitylibrary.org/page/36850144|title=General zoology, or Systematic natural history, by George Shaw|publisher=G.

==Description== The brown noddy is {{cvt|38|-|45|cm}} in length with a wingspan of {{cvt|75|-|86|cm}}. The plumage is a dark chocolate-brown with a pale-grey or white crown and forehead.

==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 platform nest, made of sticks and twigs.<ref name="Hauber2014">{{cite book|last=Hauber|first=Mark E.|url=https://books.google.com/books?id=evQvBAAAQBAJ|title=The Book of Eggs: A Life-Size Guide to the Eggs of Six Hundred of the World's Bird Species|date=1 August 2014|publisher=University of Chicago Press|isbn=978-0-226-05781-1|location=Chicago|page=173|author-link=Mark Hauber}}</ref>
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.<ref name="Hauber2014"/>
This bird lays a clutch of one pink cream egg with lilac and chestnut maculation. The egg usually measures around {{convert|52|by|35|mm|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.<ref name="Hauber2014"/> When it fledges, about six to seven weeks after hatching,<ref name="Vanner2004"/> 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.<ref name="Hauber2014"/>
