A single well-placed perch may be adequate for agile climbers like psittacines, because they tend to prefer the highest perch even if more are provided. Two perches, one on each end of the cage, should be available to birds such as finches or toucans which prefer flying or jumping. More perches may be provided in larger cages so long as they do not overcrowd the cage. Perches should be placed to prevent droppings from contaminating the bird's food or water, and to prevent the bird's tail from contacting food, water, or the floor of the cage. The use of wide bowls rather than deep cups displays the food attractively and may encourage the bird to eat new items.
Birds often overeat or chew on food dishes out of boredom.
Placing the food at the opposite end of the cage from the water will ensure that the bird gets some exercise between eating and drinking. It is recommended to have two sets of dishes so one set can be cleaned while the other is being used. Hygiene A daily cleaning of the cage floor and bowls helps to prevent problems with food spoilage and permits the owner to inspect the cage floor. Blood on the floor, or unusual condition of the droppings can alert the owner to potential signs of illness. A weekly, thorough cleaning of the cage is suggested.
