Budgerigar or common pet parakeet is an intelligent talking bird native to Australia. The smartest social bird has capability for large vocabularies. Not all birds of this species have got such great potential but some can learn 300-500 words and sentences. They have a tendency to imitate the words that have repeatedly heard from the owner. At the same time when two or more Budgerigars together in a cage they never listen to human speech and prefer to spend time with other members. Both male and female budgerigars have skill to imitate human speech. But male birds seem to be better at talking more words in the right tone.
