Flightless birds are birds that cannot fly, as they have, through evolution, lost the ability to. [1] There are over 60 extant species, [2] including the well-known ratites (ostriches, emus, cassowaries, rheas, and kiwis) and penguins. The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7

The dodo is perhaps one of the most widely recognized extinct bird species. A plump, flightless bird closely related to doves, the dodo lived solely on the island of Mauritius in the Indian Ocean. [15] [16] As is seen with regularity in species with abundant food and no predators on an isolated island, their descendants evolved per their ...
About 60 extant bird species are flightless, as were many extinct birds. [141] Flightlessness often arises in birds on isolated islands, most likely due to limited resources and the absence of mammalian land predators. [ 142 ]
