A flightless bird native to New Zealand, the Moa is believed to have been wiped out by about 1280, after the arrival of the Maoris. They were once thought to be relatives of the kiwi, but were later determined to be related to the emu and cassowary. However, new research now suggests they evolved from a South American bird called the tinamou and flew to New Zealand before losing their ability to fly. Like the Mylodon they often went into caves to die and the first fossils of their well-preserved feathers, along with bones, were discovered in the late 1830s.
