Answer: A unified global checklist of bird species for conservation
Notes: Recently, AviList, the world’s first unified global checklist of bird species, was launched to support effective bird conservation. It replaces the International Ornithological Committee (IOC) and Clements lists and will be updated every year. AviList offers the most updated and reliable classification of global bird species. It is a result of global collaboration involving BirdLife International, the Cornell Lab of Ornithology, the American Ornithologists Society, the International Ornithologists’ Union, and Avibase. The list includes 11,131 bird species, 19,879 subspecies, 2,376 genera, 252 families, and 46 orders.
