There are a few different types of parakeet cages available. These cages vary in size considerably, and though parakeets are small birds, they do best in cages that are large enough to allow them to fly from one side to another. These larger parakeet cages are often called flight cages. It is also possible to house parakeets in aviaries that can comfortably house many birds and even allow the owner to fit inside with the parakeets. Additionally, parakeet cages come in a number of different shapes, including domed and rectangular.
The smallest cages that can comfortably fit a parakeet are about 22 inches (55.9 centimeters) high, 14 inches (35.6 centimeters) deep and 18 inches (45.7 centimeters) wide. This amount of space allows a bird enough room to fly from one side of the cage to another, though there is not enough flying space for a cage of this size to be considered a flight cage. Though smaller cages are often used to house parakeets, these birds require a considerable amount of room and will not thrive in smaller spaces unless allowed ample time out of the cage.
Flight cages are considered ideal for parakeets. These cages are wider and deeper than regular parakeet cages and give the birds more opportunity to stretch their wings. The size of flight cages varies, with smaller cages having a width and depth close to 24 inches (61 centimeters) and larger cages extending to several feet (1 foot = 0.30 meters) across.
Large aviaries can also be used as parakeet cages. They can be built indoors or even outdoors if the climate is mild year round. Large aviaries are often big enough for people to comfortably sit inside, allowing them to interact with their birds without taking them out of the cage.
Parakeet cages are available in a number of shapes. The most common cages are rectangular, and give parakeets corners to hide in, a behavior they engage in naturally. Some cages are also domed, which can be aesthetically pleasing but doesn't offer much for the bird in terms of play space or security. Cages can be circular, hexagonal, or octagonal as well, and as long as they are large enough, they can work well for parakeets. Novelty cages, such as those in the shape of houses, can also be used as parakeet cages.
