You'll need to elaborate on what you mean by "they." If you mean the cost of the birds, then the range you are looking at is anything between $20 to a couple of thousand depending on the species. What kind of bird are you looking for? Parakeet, cockatiel, conure, macaw? If you aren't sure, I'd highly recommend doing some research on bird ownership and the different species of pet birds. A parakeet or parrotlet is a great bird for beginning bird enthusiasts, but I highly suggest doing that research first.
What are you looking for?
