Question

Second largest bird is
A. Emu
B. Cassowary
C. Rhea
D. Ostrich

Answer 1

Hint: Emu have tiny useless wings but has long and strong legs. They also belong to the same family to that of the Ostrich, i.e, the ratite family. They are the only bird that has calf muscles.

Complete step by step answer: Dromaius novaehollandiae which is commonly known as Emu is the second-largest flightless bird after its native relative ostrich. It is the only survivor of several forms exterminated by settlers. It is the sole member of the family Dromaiidae of the order Casuariiformes. This order also includes the cassowaries. They are stout-bodied and long-legged birds. Both the sexes are brownish, have grey-coloured necks and heads. They can dash away at a speed of 50 km/h. After mating, males help in the incubation of dark-green-coloured eggs for about sixty days. They commonly feed on insects and fruits but sometimes can damage crops. During the breeding period, they produce a loud booming sound that is correlated with their peculiar structure of the trachea. There are three species of Emu that are present in Southeast, North and Southwest Australia. The fourth species have already gone extinct. They lived in Tasmania. An Emu is more than five feet tall and weighs more than a hundred pounds.
Hence, the correct option is Emu.

Note: Emu is the second-largest bird that is native to Australia. They are opportunistically nomadic and can feed on a variety of insects and plants. They use strong claws as a defence mechanism. They are not monogamous.
