Birds for pets come as small as a Finch (3-4 inches) or as large as the Hyacinth Macaw (about 3 feet). Life spans are from 2 years to over 60 years. The colors are so numerous no one would even try to list them all. These are just a few of the things that make it hard to choose one as a pet. You have to decide how big of a cage you can afford because the bigger the bird, the larger the cage you will need. You might pay as low as $10 to over $10,000 for a domesticated parrot and as low as $7 for a cage to over $1000 for a cage for a macaw.
One big misconception that people have is that you need to have a pair of birds and not just one. This is not true. If the birds have each other to bond with, they have no need for you. The bird needs to become part of your “flock.”
Most of the over 330 species of parrots are from the tropical areas of the world, and over 240 of those 330 species have been successfully bred in captivity. Breeding in captivity has become very important here since in 1992 when the United States passed a law restricting the importing of parrots from other countries.
If you want birds to just watch, the tiny little finches are for you. You do not usually take finches out of their cages and bond with them so you might put three or four in a relatively small cage. They flutter around and do make some tweeting sounds.
If you like the small birds but want some singing, try the canaries. The male canary is much more vocal than the female; he flirts with her with his singing. Believe it or not, how well a canary sings in genetic. Canaries are not all yellow; they are also white, pink, red, and brown.
