Buying a cockatiel is a major commitment, and it's important to know what you are getting into.  All birds need to have their food and water refreshed daily and their cages cleaned frequently.  But cockatiels are especially social animals that require daily exercise and attention from their owners to keep them happy and healthy.  Be sure you have enough time to invest in your pet cockatiel, and that your family is on board with the decision. If a cockatiel sounds like too much work, consider a lower-maintenance option like a canary, or a pair of finches.  These birds also make beautiful pets, but require far less attention. The average cost can range from $120 to $250 or more, and the start-up costs for its cage, food and equipment can easily reach $300.  Also remember that the cockatiel will need food and toys, and at least one veterinary exam per year.  You can expect ongoing costs for your cockatiel to be at least $100 per year, often much more. Cockatiels need a lot of room to exercise, so you want the biggest cage you can accommodate.  The minimum recommended cage size for a single cockatiel is 24" x 24" x 24".  Be sure that the bars are spaced no more than 5/8" apart.    The cage should have at least 3 perches for the cockatiel to choose from.  The bird will also need the following:  Food and water dishes Cockatiel food A night light near the cage; some cockatiels experience "night frights" A bird bath Toys Friendly, lovable cockatiels are often given up to rescue organizations because their first owners bought them on a whim without realizing how much work a cockatiel is. The joy of taking care of a cockatiel will be magnified if you know that you did the bird a favor by saving her life. Rescue organizations for cockatiels and other birds can be found worldwide! Ask other cockatiel owners or your local avian veterinarian for tips on reputable sellers.  Your local bird club is another good resource. Make sure the seller offers a health guarantee for any pets they sell, and remember that birds that are hand-raised will generally be more friendly and sociable than aviary cockatiels that are bred and raised for display. Ask the seller lots of questions about the birds and how they were raised.  If the seller can't readily answer these questions, you should consider another shop.
