Birds are popular pet animals. They are relatively small and easy to keep in cages. However, captive birds still need exercise and activity, so it is important to get a cage that is large enough for birds to move around and play.
Some birds, known as exotic birds, come from far away and can cost thousands of dollars. Because of this, some birds are captured illegally and smuggled into the country for sale. When buying pets, it is important to know their background and to buy only from reputable dealers.
