Rhea feathers are popular for ...
The emu (/ ˈ iː m juː /; Dromaius novaehollandiae) is a species of flightless bird endemic to Australia, where it is the tallest native bird.

The emu's native ranges cover most of the ...

[ 2 ] Emu oil in the USA has a similar composition to ostrich oil, but ostrich oil has a higher omega-3 content, containing 2.1% compared to 0.25% in emu oil.
Rheas are large, flightless birds with grey-brown plumage, long legs, and long necks, similar to an ostrich. Large males of R. americana can reach 170 cm (67 in) tall at the head, 100 cm (39 in) at the back [13] and can weigh up to 40 kg (88 lb). [14] The lesser rhea is smaller, with a height of 100 cm (39 in). [13]
A comparison of a kiwi (l), ostrich (c), and Dinornis (r), each with its egg. The moa's closest relatives are small terrestrial South American birds called the tinamous, which can fly. [9] [14] [15] [16] Previously, the kiwi, the Australian emu, and cassowary [17] were thought to be most closely related to moa.
The common ostrich is the largest and heaviest living bird. Males stand 2.1 to 2.75 m (6 ft 11 in to 9 ft 0 in) tall and weigh 100 to 130 kg (220 to 290 lb), whereas females are about 1.75 to 1.9 m (5 ft 9 in to 6 ft 3 in) tall and weigh 90 to 120 kg (200 to 260 lb). [20]
The highest reliably measured running speed for ostriches is 61 km/h (38 mph), obtained by speedometer reading when a car was chasing an ostrich in a straight line chase to force it to move as fast as it could. [53] Although there are reports of speeds of 72–97 km/h (45–60 mph) for ostriches, none are confirmed. [54] Emu (on land)
