Elephant bird Elephant bird Elephant birds are members of the extinct ratite family Aepyornithidae, made up of large to enormous flightless birds that once lived on the island of Madagascar. They became extinct, perhaps around 1000–1200 CE, for reasons that are unclear, although human activity is the suspected cause. Elephant birds comprised the genera "Mullerornis", "Vorombe" and "Aepyornis". While they were in close geographical proximity to the ostrich, their closest living relatives are kiwi, suggesting that ratites did not diversify by vicariance during the breakup of Gondwana but instead evolved from ancestors that dispersed more recently by flying.

The responsible factors for the dwarfing of island mammals are thought to be the reduction in food availability, predation and competition. Straight-tusked elephant The straight-tusked elephant ("Palaeoloxodon antiquus") is an extinct species of elephant that inhabited Europe during the Middle and Late Pleistocene (781,000–50,000 years before present). Some experts regard the larger Asian species, "Palaeoloxodon namadicus", as a variant or subspecies. It was formerly thought to be closely related to the living Asian elephant; however, in 2016, DNA sequence analysis showed that its closest extant relative is actually the African forest elephant, "Loxodonta cyclotis".
