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 .
Flightless birds are birds that cannot fly. They have, through evolution, lost the ability to fly. [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

Gastornis is an extinct genus of large, flightless birds that lived during the mid-Paleocene to mid-Eocene epochs of the Paleogene period. Fossils have been found in Europe, North America and possibly Asia.
The first illustration of the South Island takahē from Gideon and Walter Mantell's notice of the discovery in 1850. Anatomist Richard Owen was sent fossil bird bones found in 1847 in South Taranaki on the North Island by collector Walter Mantell, and in 1848 he coined the genus Notornis ("southern bird") for them, naming the new species Notornis mantelli.

The tops of elephant bird skulls display punctuated marks, which may have been attachment sites for fleshy structures or head feathers. [18] Mullerornis is the smallest of the elephant birds, with a body mass of around 80 kilograms (180 lb), [16] with its skeleton much less robustly built than Aepyornis. [19]
These birds are still fully capable of flying. They also have close relatives where the furcula is vestigial, reduced to a thin strap of ossified ligament, seemingly purposeless. Other species have evolved the furcula in the opposite direction, so that it has increased in size and become too stiff or massive to act as a spring.
Struthionidae (/ ˌ s t r uː θ i ˈ ɒ n ə d iː /; from Latin strūthiō 'ostrich' and Ancient Greek εἶδος (eîdos) 'appearance, resemblance') is a family of flightless birds, containing the extant ostriches and their extinct relatives.
