We all love birds, don’t we? Birds can surprise us by their flights. There are many birds with flight but some have lost their ability to fly. The ability to fly is determined by shape, size and height. Griffon Vulture is regarded as the highest flying bird (37,000 feet high) followed by common crane (33,000 feet high).
The Ostrich, Rhea, Emu and Cassowary cannot fly for various reasons. Though they have lost their ability to fly they can run fast on their long, strong legs. Ostriches live in Africa and are found on the grassy places. The Rhea of South America looks rather like the Ostrich but it is smaller and has three toes on each feet, while the Ostrich has only two.
Emu is the second-largest bird. Next to its relative, Ostrich. Emu is found in Australia. It can sprint at 50 km/h. Cassowary is largely found in Papua, New Guinea. It is omnivorous and can run at 501 km/ h. It is very interesting to read about our flightless friends. Go, explore more!
