A cage is your bird's sanctuary. Birds require a lot from a cage for physical and psychological well being.
Birds, both large and small, need adequate space in their cage to engage in some of their natural behaviors. Large birds need enough room to play with toys and flap their wings, while small birds need space to flit and interact with their cage mates. Without sufficient space to engage in normal behaviors, birds may develop behavioral problems, such as aggression, feather plucking, and various phobias.
A cage that is too small does not allow room for toys and other accessories that are vital for creating an enriching environment. On the other hand, a cage that is too large can be intimidating for shy birds. A flight cage or aviary, which will not be your bird's main domicile, can be as big as you wish as long as bar spacing is narrow enough so your bird does not get his head caught between the bars, wide enough to accommodate perching, yet not so wide that your bird can escape. Proper bar spacing is important for cages as well.
| We recommend the following:|
||Finch, canary, parrotlet, parakeet, lovebird
||no more than 5/8"
||1/2" to 1"
|Medium||Cockatiel, conure, lory, senegal
||1/2" to no more than 7/8"
||3/4" to 1.5"
|Large||African Grey, Amazon, macaw, cockatoo
||3/4" to no more than 1-3/8"
||1.5" to 3"
Another important factor is the setting your bird cage will have. If selecting a large pet bird cage, consider whether it comes fully assembled or if you need to assemble it at home. If it comes fully assembled or you plan to move it around your home, make sure it will fit through all doorways involved. Include dimensions for the seed tray (if it has one you'll have less mess) and feeders accessible from outside the cage.
When your bird is tired or just needs a break, ensure his home is a happy place, a place where he can find fun, food, and comfort.
