Choosing a cage.
Your bird need the largest cage you can afford in order to benefit from daily exercise. The cage you select should be large enough so your bird can fully extend its wings without having the wings touch the sides of the cage . The bird should also have ample clearance for its head from the cage ceiling and its tail from the cage floor when sitting on its perch. In addition to your bird, the cage must hold a few perches, some toys, a food bowl, and a water bowl.
When choosing your bird's cage, keep in mind that the smaller birds are like little airplanes and love to fly in their cage. For this reason, a wider cage that offers horizontal space for short flights is preferred to tall cages that don't provide much flying room.
