A zoo is a place where various birds, animals and reptiles are kept. A zoo does not contain ordinary birds and animals which we usually see in our villages and towns. It contains those birds and animals which we cannot generally see. Most of them live in forests. Some of them are brought from other countries also, as they are not found in our country. A visit to a zoo is a pleasure. It is informative and educative too. Zoos are there in almost all the big cities. We have zoos in Delhi, Calcutta, Bombay, Madras, Mysore and also in Hyderabad. The zoo at Hyderabad is named as Nehru Zoological Park.
