Broad-billed parrot sketch actually shows that the wings are not particularly short. They appear broad, as they commonly are in forest-adapted species, and the alula appears large, a feature of slow-flying birds. Its sternal keel was reduced, but not enough to prevent flight, as the adept flying "Cyanoramphus" parrots also have reduced keels, and even the flightless kakapo, with its vestigial keel, is capable of gliding. Furthermore, Hoffman's account states that it could fly, albeit with difficulty, and the first published illustration shows the bird on top of a tree, an improbable position for a flightless bird.

Flightless dung beetle Flightless dung beetle The flightless dung beetle ("Circellium bacchus") is a species of dung beetle endemic to a few areas of South Africa, including the Addo Elephant National Park and the Buffalo Valley Game Farm. It is the only species in the genus Circellium. The loss of flight allows the beetle to use the empty space below the elytra as a carbon dioxide storage tank, creating a unique breathing mechanism which conserves water, a valuable survival trait in the arid regions it lives in. The species was originally widespread in Southern Africa, but it only survives in the few areas
