Parrots live in tropical and subtropical regions and continents around the globe, including Africa, South America, Central America, Southeast Asia, South Asia, Oceania and Australia. There are around 370 known parrot species in the world.
Although most parrots live in tropical climates, keas, maroon-fronted parrots and thick-billed parrots make their homes in snowy alpine areas. Most parrots nest in trees, but parrots that do not live in trees may use rocky outcrops, termite mounds and cacti for nests. Notably, United States was once home to a species of parrot known as the Carolina parakeet, but it was hunted to extinction in the early 20th century.
