emu
Other forms: emus
An emu is a very large, flightless bird that is only slightly shorter than its close relative, the ostrich. You're likely to see emus if you travel around their native continent of Australia.
Emus reign as the biggest bird in Australia, growing to a height of six feet or more as adults. These long-legged birds have soft brown feathers and relatively small wings that they flap as they run (sometimes sprinting at 30 miles per hour), though sadly, they're unable to take flight. Etymologists guess that emu comes from the Portuguese word for "ostrich," ema.
