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.
Cinereous tinamou The cinereous tinamou ("Crypturellus cinereus"), also known as brushland tinamou, is a type of ground bird found in swamp and lowland forests in northern South America. They have some localized names that have been used by the indigenous people such as in Amazonas where they are called "inambu-pixuna", and in Pará, Brazil where they are called "nambu-sujo". Also, throughout their range they are called "inhambu-preto". Cinereous tinamous have been around for many centuries. They are part of the oldest families of the world today and have fossils discovered dating back tens of millions of years. Their quick reflexes play a role in their ability to survive.
