It is found on the Atlantic Coast from [[New Jersey]] to the mouth of the [[Amazon River]], and along the [[Pacific coast|Pacific Coast]] from [[British Columbia]] to Peru, including the [[Galapagos Islands]]. The [[nominate subspecies]] in its [[Glossary of bird terms#breeding plumage|breeding plumage]] has a white head with a yellowish wash on the crown. The [[nape]] and neck are dark maroon&ndash;brown. The upper sides of the neck have white lines along the base of the [[gular pouch]], and the lower fore neck has a pale yellowish patch. The male and female are similar, but the female is slightly smaller. The nonbreeding adult has a white head and neck. The pink skin around the eyes becomes dull and gray in the nonbreeding season. It lacks any red hue, and the pouch is strongly olivaceous ochre-tinged and the legs are olivaceous gray to blackish-gray. The brown pelican mainly feeds on fish, but occasionally eats [[amphibian]]s, [[crustacean]]s, and the [[Bird egg|eggs]] and nestlings of birds. It nests in [[Colony (biology)|colonies]] in secluded areas, often on islands, vegetated land among sand dunes, thickets of shrubs and trees, and [[Mangrove swamp|mangroves]]. Females lay two or three oval, chalky white eggs. [[Incubation period|Incubation]] takes 28 to 30 days with both sexes sharing duties. The newly hatched chicks are pink, turning gray or black within 4 to 14 days. About 63 days are needed for chicks to [[fledge]]. Six to 9 weeks after hatching, the juveniles leave the nest, and gather into small groups known as pods. The brown pelican is the [[List of national birds|national bird]] of [[Collectivity of Saint Martin|Saint Martin]], [[Barbados]], [[Saint Kitts and Nevis]], and the [[Turks and Caicos Islands]], and the official [[List of U.S. state birds|state bird]] of [[Louisiana]], appearing on the flag, seal, or coat of arms of each. It has been rated as a [[species of least concern]] by the [[International Union for Conservation of Nature]]. It was listed under the [[Endangered Species Act|United States Endangered Species Act]] from 1970 to 2009, as pesticides such as [[dieldrin]] and [[DDT]] threatened its future in the [[Southeastern United States]] and [[California]]. In 1972, the use of DDT was banned in [[Florida]], followed by the rest of the United States. Since then, the brown pelican's population has increased. In 1903, [[Theodore Roosevelt]] set aside the first [[National Wildlife Refuge]], Florida's [[Pelican Island National Wildlife Refuge|Pelican Island]], to protect the species from hunters. == Taxonomy == The brown pelican was [[species description|described]] by Swedish zoologist [[Carl Linnaeus]] in the 1766 12th edition of his ''[[Systema Naturae]]'', where it was given the binomial name of ''Pelecanus occidentalis.''<ref>{{Cite book|url=https://www.biodiversitylibrary.org/item/54275#page/212/mode/1up|title=Proceedings of the United States National Museum|volume=v. 87 1941|last=Museum|first=United States National|publisher=Smithsonian Institution Press|year=1941|pages=180|language=en}}</ref> It belongs to the [[New World]] clade of the genus ''[[Pelecanus]]''.<ref name=":02">{{Cite journal|last1=Kennedy|first1=Martyn|last2=Taylor|first2=Scott A.|last3=Nádvorník|first3=Petr|last4=Spencer|first4=Hamish G.|date=2013|title=The phylogenetic relationships of the extant pelicans inferred from DNA sequence data|journal=Molecular Phylogenetics and Evolution|volume=66|issue=1|pages=215–222|doi=10.1016/j.ympev.2012.09.034|pmid=23059726}}</ref> Five [[subspecies]] of the brown pelican are recognized.<ref>{{Cite book|url=https://books.google.com/books?id=YrFFAAAAYAAJ|title=Grzimek's Animal Life Encyclopedia, Volume 8: Birds I|last1=Grzimek|first1=Bernhard|last2=Schlager|first2=Neil|date=2003|publisher=Gale|isbn=978-0-7876-5784-0|pages=231|language=en}}</ref><ref name="hbw2">{{cite journal|url=http://www.hbw.com/species/brown-pelican-pelecanus-occidentalis|title=Brown Pelican (''Pelecanus occidentalis'')|last1=Turner|first1=Angela|year=2020|editor1-last=Elliott|editor1-first=A.|editor2-last=Christie|editor2-first=D.A.|journal=Handbook of the Birds of the World Alive|publisher=Lynx Edicions|location=Barcelona|doi=10.2173/bow.brnpel.01 |access-date=August 18, 2017|url-access=subscription|editor3-last=Jutglar|editor3-first=F.|editor4-last=de Juana|editor4-first=E.|editor5-last=Kirwan|editor5-first=G.M.}}</ref> At least some of these subspecies are [[Genetics|genetically]] distinct despite similar [[phenotype]]s.

Peters]] divided ''Pelecanus'' into three subgenera, placing brown pelican (including Peruvian pelican) in a monospecific ''Leptopelicanus'', American white pelican in a monospecific ''Cyrtopelicanus'', and all the rest in the subgenus ''Pelecanus'', a treatment which was also followed by [[Jean Dorst]] and Raoul J. Mougin in 1979. Andrew Elliott in 1992, and [[Joseph Bryan Nelson|Joseph B. Nelson]] in 2005, considered the deepest division among pelicans to lie between brown (plus Peruvian) pelican on the one hand, and the white-plumaged pelicans on the other (among which the large ground-nesting American white, [[Australian pelican|Australian]], great white, and [[Dalmatian pelican|Dalmatian]] pelicans were thought to form a clade, and the smaller tree-nesting [[pink-backed pelican|pink-backed]] and [[spot-billed pelican|spot-billed]] pelicans were likewise considered sister taxa). In 1993, [[Paul Johnsgard]] hypothesized that the Americas were colonized relatively late in pelican evolution, with the family originating in Africa or South Asia; however, he later supported the prevailing view that brown (with Peruvian) was the most divergent pelican (and considered American white and great white pelicans to be close relatives, implying two independent dispersals of pelicans into the Americas, with that of the ancestor of brown and Peruvian pelicans occurring early on). [[Charles Sibley|Sibley]] and [[Jon E. Ahlquist|Ahlquist]]'s [[DNA-DNA hybridization]] studies and [[UPGMA]] tree published in 1990 supported brown pelican as sister to a clade comprising all the white-plumaged pelicans analyzed, including American white pelican (although the relationships among the latter group differed).<ref name=":02" /> With better genetic data and more modern methods, a new phylogenetic hypothesis of pelican relationships has arisen, which contrasts with the traditional view of brown and Peruvian being the most divergent pelicans based on their distinctive plumage and behavior (and early molecular data). Rather than the brown-plumaged pelicans and white-plumaged pelicans forming two reciprocally monophyletic groups, the American white pelican is sister to brown and Peruvian pelicans, the three together forming an exclusively New World pelican clade. (Among the other pelicans, pink-backed, Dalmatian, and spot-billed pelicans are close relatives, together sister to Australian pelican. Great white pelican has no particularly close relatives; while it may be sister to the previous four, this relationship had low statistical support.)<ref name=":02" /> ==Description== [[File:Brown Pelican open mouth.JPG|thumb|Brown pelican showing throat pouch]] The brown pelican is the smallest of the eight extant pelican species, but is often one of the larger seabirds in their range nonetheless.<ref>{{Cite book|url=https://books.google.com/books?id=CnYMX70y1oAC&pg=PA23|title=A Field Guide to the Birds of the West Indies|last=Bond|first=James|date=1999|publisher=Houghton Mifflin Harcourt|isbn=978-0-618-00210-8|pages=23–24|language=en}}</ref><ref>Daniels, R.

Some migration is observed, especially in the northern parts of the species's range, but these movements are often erratic, depending on local conditions. While usually restricted to coastal regions, brown pelicans occasionally wander inland, and there are records of [[vagrancy (biology)|vagrant]] individuals across much of the interior of North America. The species also occasionally wanders along the coasts of the Americas outside its normal range, with vagrants reported as far north as [[Southeast Alaska]] and [[Newfoundland]], as far south as central [[Chile]] (well into the range of the closely related Peruvian pelican), and as far east in South America as [[Alagoas]]. Rare inland vagrants, generally caused by hurricanes or El Niño phenomena, have been reported from the [[Andean natural region|Colombian Andes]]. They were first recorded in July 2009 in the [[Interandean Valles|Interandean Valley]], where they remained for at least 161 days.

'THIS IS BATMAN similar, but the female is slightly smaller. The nonbreeding adult has a white head and neck. The pink skin around the eyes becomes dull and gray in the nonbreeding season. It lacks any red hue, and the pouch is strongly olivaceous ochre-tinged and the legs are olivaceous gray to blackish-gray. The brown pelican mainly feeds on fish, but occasionally eats [[amphibian]]s, [[crustacean]]s, and the [[Bird egg|eggs]] and nestlings of birds. It nests in [[Colony (biology)|colonies]] in secluded areas, often on islands, vegetated land among sand dunes, thickets of shrubs and trees, and [[Mangrove swamp|mangroves]]. Females lay two or three oval, chalky white eggs. [[Incubation period|Incubation]] takes 28 to 30 days with both sexes sharing duties. The newly hatched chicks are pink, turning gray or black within 4 to 14 days. About 63 days are needed for chicks to [[fledge]]. Six to 9 weeks after hatching, the juveniles leave the nest, and gather into small groups known as pods. The brown pelican is the [[List of national birds|national bird]] of [[Collectivity of Saint Martin|Saint Martin]], [[Barbados]], [[Saint Kitts and Nevis]], and the [[Turks and Caicos Islands]], and the official [[List of U.S. state birds|state bird]] of [[Louisiana]], appearing on the flag, seal, or coat of arms of each. It has been rated as a [[species of least concern]] by the [[International Union for Conservation of Nature]]. It was listed under the [[Endangered Species Act|United States Endangered Species Act]] from 1970 to 2009, as pesticides such as [[dieldrin]] and [[DDT]] threatened its future in the [[Southeastern United States]] and [[California]]. In 1972, the use of DDT was banned in [[Florida]], followed by the rest of the United States. Since then, the brown pelican's population has increased.

Peters]] divided ''Pelecanus'' into three subgenera, placing brown pelican (including Peruvian pelican) in a monospecific ''Leptopelicanus'', American white pelican in a monospecific ''Cyrtopelicanus'', and all the rest in the subgenus ''Pelecanus'', a treatment which was also followed by [[Jean Dorst]] and Raoul J. Mougin in 1979. Andrew Elliott in 1992, and [[Joseph Bryan Nelson|Joseph B. Nelson]] in 2005, considered the deepest division among pelicans to lie between brown (plus Peruvian) pelican on the one hand, and the white-plumaged pelicans on the other (among which the large ground-nesting American white, [[Australian pelican|Australian]], great white, and [[Dalmatian pelican|Dalmatian]] pelicans were thought to form a clade, and the smaller tree-nesting [[pink-backed pelican|pink-backed]] and [[spot-billed pelican|spot-billed]] pelicans were likewise considered sister taxa). In 1993, [[Paul Johnsgard]] hypothesized that the Americas were colonized relatively late in pelican evolution, with the family originating in Africa or South Asia; however, he later supported the prevailing view that brown (with Peruvian) was the most divergent pelican (and considered American white and great white pelicans to be close relatives, implying two independent dispersals of pelicans into the Americas, with that of the ancestor of brown and Peruvian pelicans occurring early on). [[Charles Sibley|Sibley]] and [[Jon E. Ahlquist|Ahlquist]]'s [[DNA-DNA hybridization]] studies and [[UPGMA]] tree published in 1990 supported brown pelican as sister to a clade comprising all the white-plumaged pelicans analyzed, including American white pelican (although the relationships among the latter group differed).<ref name=":02" /> With better genetic data and more modern methods, a new phylogenetic hypothesis of pelican relationships has arisen, which contrasts with the traditional view of brown and Peruvian being the most divergent pelicans based on their distinctive plumage and behavior (and early molecular data). Rather than the brown-plumaged pelicans and white-plumaged pelicans forming two reciprocally monophyletic groups, the American white pelican is sister to brown and Peruvian pelicans, the three together forming an exclusively New World pelican clade. (Among the other pelicans, pink-backed, Dalmatian, and spot-billed pelicans are close relatives, together sister to Australian pelican. Great white pelican has no particularly close relatives; while it may be sister to the previous four, this relationship had low statistical support.)<ref name=":02" /> ==Description== [[File:Brown Pelican open mouth.JPG|thumb|Brown pelican showing throat pouch]] The brown pelican is the smallest of the eight extant pelican species, but is often one of the larger seabirds in their range nonetheless.<ref>{{Cite book|url=https://books.google.com/books?id=CnYMX70y1oAC&pg=PA23|title=A Field Guide to the Birds of the West Indies|last=Bond|first=James|date=1999|publisher=Houghton Mifflin Harcourt|isbn=978-0-618-00210-8|pages=23–24|language=en}}</ref><ref>Daniels, R.

Some migration is observed, especially in the northern parts of the species's range, but these movements are often erratic, depending on local conditions. While usually restricted to coastal regions, brown pelicans occasionally wander inland, and there are records of [[vagrancy (biology)|vagrant]] individuals across much of the interior of North America. The species also occasionally wanders along the coasts of the Americas outside its normal range, with vagrants reported as far north as [[Southeast Alaska]] and [[Newfoundland]], as far south as central [[Chile]] (well into the range of the closely related Peruvian pelican), and as far east in South America as [[Alagoas]]. Rare inland vagrants, generally caused by hurricanes or El Niño phenomena, have been reported from the [[Andean natural region|Colombian Andes]]. They were first recorded in July 2009 in the [[Interandean Valles|Interandean Valley]], where they remained for at least 161 days.

Rather than the brown-plumaged pelicans and white-plumaged pelicans forming two reciprocally monophyletic groups, the American white pelican is sister to brown and Peruvian pelicans, the three together forming an exclusively New World pelican clade. (Among the other pelicans, pink-backed, Dalmatian, and spot-billed pelicans are close relatives, together sister to Australian pelican.
