Birds are the most beautiful living creature on earth with an excellent ability to fly. There are thousands of bird’s species with some few differences in their social and environmental behaviour. Birds reside in different regions of the world and migrate to various other habitats. Some species of birds can survive in limited climatic conditions. Emu and ostrich both are the two most abundant birds in the world. Although both are flightless birds but are fast runners, people might get confused and think what is the difference between an emu and an ostrich as both are big birds with the feathery body, long neck and legs. But, these two birds are not similar and differ in certain aspects. To more compare three different types of birds- ostrich vs emu vs flamingo.
