context_page_description: Although Costa Rica is a small country, it is in the bird-rich neotropical region and has a huge number of species for its area. The official bird list published by the Costa Rican Rare Birds and Records Committee of the Asociación Ornitológica de Costa Rica contained 922 species as of August 2019. This number is more than have been recorded in all of the 49 mainland United States and Canada combined. Of those species, seven are endemic, 69 are rare or accidental, and four have been introduced by humans. Another 73 are near-endemic with ranges that include only Costa Rica and Panama. Twenty-seven species, including five of the seven endemics, are globally vulnerable or endangered. Over an area of 51,100 km², an area smaller than West Virginia, this is the greatest density of bird species of any continental American country. About 600 species are resident, with most of the other regular visitors being winter migrants from North America.
  Costa Rica's geological formation played a large role in the diversification of avian species.
