A well raised and trained macaw can make a good pet under the proper conditions. You have to restrict where they can go, because unsupervised they will bite and destroy anything they can reach. They will make an awful screeching scream, sometimes early in the morning or when they are in need of company (that's you), which means you need a very large yard, so they can be away from your neighbors and bedroom. You can buy a very young hand-fed macaw for under $100 dollars in Colombia. The outdoor markets will sell (normally illegally) all types of exotic colorful birds and animals.
