A、They learn sounds more quickly than other birds. B、They can imitate the most different sounds. C、They think much while learnin

Do animals think? (26) Many of them are like children in their sports. We notice this to be true very often with dogs and cats, but it is true with other animals as well.
    Some birds are very lively in their sports; and the same is true with some insects. (27) The ants, hardworking as they are, have their times for play. They run races; they wrestle; and sometimes they have mock fights together. There are many animals, however, that never play; their thoughts seem to be of more sober kind. We never see frogs engaged in sports. They all the time appear to be very grave. The same is true of the owl, who always looks as if he were considering some important question.
    Animals think much while building their houses. The bird searches for what it can use in building its nest, and in doing this it thinks. The beavers think as they build their dams and their houses. They think in getting their materials , and also in arranging them. (28) Some spiders build houses which could scarcely have been made except by some thinking creatures.
    As animals think, they learn. Some learn more than others. (29) The parrot learns to talk, though in some other respects it is quite stupid. The mocking bird learns to imitate a great many different sounds. The horse is not long in learning many things connected with the word which he has to do.
