During the twentieth century, habitat destruction has caused many species of animals to decline or has lead to extinction. Through the captive breeding, in a small way we help to preserve a few species as their habitat is destroyed.
Many birds can survive in a variety of environments.
Still many others require a specific environment and diet. Some are quite adaptable, others are not. Most species of parrots are forest dwellers and unable to adapt once their home is gone. Two out of three birds are forest dwellers. Once their home is gone their populations can dwindle to extinction.
