An ordinary plant mister and plastic dish for the bird's bath are fine but should not be used for anything else to prevent contamination. Nest boxes Nest boxes should be supplied for a place to hide, especially for the smaller birds. These boxes can be attached toward the top of the cage and should be easy to remove and clean. A cover made to fit the cage can be purchased. An old sheet or pillowcase will also work.
Some birds never have their cage covered while others have their cage covered at night.
A cage cover should not be used as punishment or for extended periods of time outside of sleeping hours. Toys Toys should be plentiful and alternated. They are what will occupy the bird through the largest part of the day while the owners are gone. Small birds like small, lightweight toys and tiny mirrors. Larger birds like to manipulate toys with their beak, tongue, and feet.
