American scientists have found that some birds are more intelligent than experts had originally believed. The scientists say birds have abilities that involve communication and different kinds of memory. In some unusual cases, their abilities seem better than those of humans.
Griffin is a Grey parrot. He lives in his laboratory at the Massachusetts Institute of Technology in Cambridge. Griffin can arrange objects in order of size. He can also combine words in the right order. For example, he will combine words when asking for a piece of food.
    Some birds have other memory skills. For example, they collect and store thousands of seeds in autumn, and find them later in winter. These birds use natural objects to find the seeds they have stored. They use at least three objects, such as rocks or trees, to find the stored seeds.
    A jay can be trained to choose one object instead of another. The bird uses this skill to receive a prize, such as food.Scientists also say some birds can learn as many as two thousand different songs. They say songs may have developed as a way for birds to communicate with other birds.
    Scientists believe that birds must have a special guidance system in their brain. Understanding how a bird’s brain operates may help us better understand how a human brain processes information.
