Colour helps you see things. But man and some monkeys and apes (猿) are the only mammals (哺乳动物) that can see colour.       any other mammals, such as the dog, the world      a black-white photo. Dogs hunt mainly by listening and smelling.
Like      animals, dogs see best when things move. The animals they hunt seem to know this. A rabbit or deer will freeze when they find that they are being hunted. Then the dog      see it at all.
Birds can see colour. They need to, because when they fly, they need to find places to land. Colour helps them know       the place is and what it is like so that they are able to catch flying things in the air or to       something they think safe.
Some birds see things even       than man. The birds that eat bugs (虫子) can see them from far away. And even a very young bird can see a hawk       the sky. So good eyes and being able to see colours help birds       food and also help them find out      there are other animals that are dangerous to them.
