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
Like the penguins, puffins have a white chest, black back and short stubby wings providing excellent swimming ability in icy water. But, unlike penguins, puffins can fly, as flightless birds would not survive alongside land-based predators such as polar bears and foxes; there are no such predators in the Antarctic.
Due to their short wings, auks have to flap their wings very quickly to fly. Although not to the extent of penguins, auks have largely sacrificed flight, and also mobility on land, in exchange for swimming ability; their wings are a compromise between the best possible design for diving and the bare minimum needed for flying.
