Cages should be as large as you have room for. Preferably they should be wide enough for the birds to move freely to different perch levels. Tall narrow cages are not recommended because birds tend to move laterally and not vertically. Your cage should be large enough for your bird to express its natural inclinations to move around, to flap its wings and to preen without touching the sides of the cage. A paper-lined metal tray below a grid allows for easier cleaning of droppings and discarded food.
Scrub perches regularly.
The best perches can be made from natural tree branches such as fruit and citrus trees. Natural perches offer proper footing and exercise as compared to smooth round poles or plastic perches. Sandpaper perches should be removed as they irritate the bird's feet and fail to trim the nails as advertised. Nails should be trimmed by a veterinarian or someone with experience in performing this task. Place perches in such a way that the birds' droppings won't contaminate food or water.
