The bird kicked the younger boy, who fell and ran away as his older brother struck the bird. The older McClean then tripped and fell to the ground. While he was on the ground, the cassowary kicked him in the neck, opening a 1.25-centimetre (0.49 in) wound that severed his jugular vein .
The only known species of flightless bird in which wings completely disappeared was the gigantic, herbivorous moa of New Zealand, hunted to extinction by humans by the 15th century. In moa, the entire pectoral girdle is reduced to a paired scapulocoracoid , which is the size of a finger.

Bird wings are a paired forelimb in birds. The wings give the birds the ability to fly, creating lift. Terrestrial flightless birds have reduced wings or none at all (for ...

Males are larger and heavier than females, weighing 35–49 g (1.2–1.7 oz), average 40.5 g (1.43 oz), compared to 34–42 g (1.2–1.5 oz), average 37 g (1.3 oz ...
The wings are not reduced in size like some other flightless birds, and have a span of around 77.5 cm (30 + 1 ⁄ 2 in), but they lack the musculature for flight. [ 5 ] [ page needed ] [ 9 ] These wings are also used for a 'broken-wing' display, a behaviour shared with their relative sunbittern, used to fake an injury and draw the attention of ...
Here's a riddle: how did an order of flightless birds manage to spread to places they would have had to fly to? Rheas live in South America, cassowaries and emus in Australia, kiwis in New Zealand ...
The Rodrigues solitaire (Pezophaps solitaria) is an extinct flightless bird that was endemic to the island of Rodrigues, east of Madagascar in the Indian Ocean. Genetically within the family of pigeons and doves, it was most closely related to the also extinct dodo of the nearby island Mauritius, the two forming the subfamily Raphinae.
Unlike other flightless birds, the ratites have no keel on their sternum—hence the name, from the Latin ratis ('raft', a vessel which has no keel—in contradistinction to extant flighted birds with a keel). [7] Without this to anchor their wing muscles, they could not have flown even if they had developed suitable wings.
