The term 'ostrichlike bird' refers to four species of large, flightless birds that are native to Australia, New Zealand, and South America. These birds are the EMU (3 letters), MOA (3 letters), RHEA (4 letters), and emeu (4 letters). The EMU is the largest bird in Australia and the second-largest living bird in the world. The MOA was a giant bird that went extinct in the late 19th century. The RHEA is native to South America and is the largest bird in the continent. The emeu is found in Australia and is the smallest of the four species. All four species are characterized by their long legs and necks, and their inability to fly.
