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 basal metabolic rate of flighted species is much higher than that of flightless terrestrial birds. [34] But energetic efficiency can only help explain the loss of flight when the benefits of flying are not critical to survival. Research on flightless rails indicates the flightless condition evolved in the absence of predators. [35]
National Geographic's Ed Yong says Cooper's research supports a newer theory about the flightless bird family: that they "evolved from small, flying birds that flapped their way between continents ...
Rheidae / ˈ r iː ɪ d iː / is a family of flightless ratite birds which first appeared in the Paleocene. [2] It is today represented by the sole living genus Rhea, but also contains several extinct genera. [3]
