Bird extinction

Bird extinction is the complete elimination of all species members under the taxonomic class, Aves. Out of all known bird species, (approximately 11,154), 159 (1.4%) have become extinct, with 226 (2%) being critically endangered.[1] There is a general consensus among ornithologists that if anthropogenic activities continue as current trends suggest, one-third of all bird species, and an even greater proportion of bird populations, will be rendered extinct by the end of the 21st century.[2]
For critically endangered species, scientists estimate they will face extinction in a few decades without proper conservation efforts; for some of these species, the current presence of extant populations is uncertain.[3]
