Birds are wonderful companions if certain caveats are kept in mind. The first is to not get a bird unless you have some extra time for interaction and play....especially with the larger bird species. Bigger birds are very social, and require supervised time out of the cage, along with some training activities. Smaller birds, such as finches, may be kept in groups, and do not have the one-on-one time requirements of the larger avian types.
Feeding the appropriate diet is essential. "Complete type diets" should form the basis for most species. Some seeds and healthy table foods may be added, but should be the minor part of a bird's total intake. Most veterinarians can tell you that ill birds are usually those with seed-based feeding programs, since they are generally deficient in vitamins, minerals and protein. "Conversion" of a bird from seeds to complete diets takes patience and effort. We can board your bird at our hospital and accomplish this process for you, if you so wish.
Supplemental heat is a good idea for most birds. We recommend a heat lamp and digital thermometer. 76-82 F are good environmental temperatures for most tropical species. Be sure and research the exact requirements for your particular type bird, however.
Don't forget that cage and utensil cleaning is a big part of owning a pet bird. There should not be a day that caging and bowls are not scoured, and preferably disinfected as well. Flying feathers and food materials make a hand vacuum almost essential. Personal hygiene is a requirement as well....hand washing after handling will help prevent the potential for human illness.
Lastly, a "pet savings account" is a great idea. Birds can be costly, and a serious illness can break a bank account. Even food and toys can be expensive. Don't fail to prepare for illness or injury. Many pet birds suffer without care due to owner financial strain.
Lastly, do your research and make sure you know what you're "getting into." The internet is a wealth of information, and you should speak with bird breeds as well. We are more than happy to field calls at our hospital, too. It's never wrong to start with a smaller, inexpensive bird before you make the foray into the larger parrots.
