Colombia has the largest number of bird species of any South American country.
Its exceptional diversity comes from Colombia’s geography: the country contains Caribbean lowlands, Pacific rainforests, Amazonian forest, Andean valleys, páramo ecosystems, and snow-covered mountain ranges. These habitats sit at the meeting point of several major biogeographic regions, giving birds many ecological niches.
Colombia’s bird list contains roughly 1,900 recorded species, although the exact total changes as taxonomists revise classifications and observers document new records. Brazil and Peru also have extraordinarily rich birdlife, but their recorded totals remain lower in standard country comparisons.
A common mix-up is confusing species diversity with the number of endemic species or with a single bird-counting event. Colombia leads the overall species tally; other countries may lead particular measures, such as the number seen during a specific survey or the number of species found only within their borders.
