The African ostrich is the world's tallest living bird; where does the second tallest, the emu, come from?
Emu The emu ("Dromaius novaehollandiae") is the second-largest living bird by height, after its ratite relative, the ostrich. It is endemic to Australia where it is the largest native bird and the only extant member of the genus "Dromaius". The emu's range covers most of mainland Australia, but the Tasmanian emu and King Island emu subspecies became extinct after the European settlement of Australia in 1788. The bird is sufficiently common for it to be rated as a least-concern species by the International Union for Conservation of Nature.
Amazonian umbrellabird The Amazonian umbrellabird ("Cephalopterus ornatus") is a species of bird in the family Cotingidae native to the Amazon basin with a separate population on the eastern slopes of the Andes. The male bird is entirely black, with a black crest and inflatable wattle on the throat, and at 48 to , may be the largest passerine bird in South America. The female is slightly smaller. Both have an undulating flight, described as woodpecker-like, and the male has a loud, booming call.
