context_page_description: Brazil has one of the richest bird diversities in the world. The avifauna of Brazil include a total of 1823 confirmed species of which 238 are endemic. Five have been introduced by humans, 78 are rare or vagrants, and four are extinct or extirpated. An additional 21 species are hypothetical.
  Brazil hosts about 60% of the bird species recorded for all of South America. These numbers are still increasing almost every year, due to new occurrences, new species being described, or splits of existing species. About 10% of the bird species found in Brazil are, nonetheless, threatened.
  In June 2013 a simultaneous discovery of fifteen bird species in Brazil was announced, the first such since 1871, when August von Pelzeln described forty new species. The birds were from the families Corvidae, Thamnophilidae, Dendrocolaptidae, Tyrannidae, and Polioptilidae. Eleven of the new species are endemics of Brazil and four also inhabit Peru and Bolivia.
  Except as an entry is cited otherwise, the list of species is that of the South American Classification Committee of the American Ornithological Society. The list's taxonomic treatment and nomenclature are also those of the SACC.
