The macaw is the largest bird from tropical regions. Most range from 35 to 50 inches long. The diet of the macaw usually includes tropical fruits, nuts, plants, insects, and even snails. Another thing the macaw eats is red clay on river banks. Although scientists are unsure why they do this, some believe it is to obtain needed minerals or to detoxify poisons from the plants they eat.

An interesting fact about the macaw is that when one macaw finds a mate, it stays with that mate until one of them dies. Although the macaw is known to mimic human speech, in the wild they have loud ear-piercing voices. These birds are also believed to communicate very well within their species.
