Polly can eat just about anything from the four food groups that you do. Some birds are more finicky than others, but try giving yours different foods and see what he likes. Keep in mind that if it's bad for you, it's probably bad for him too. Pretty bird Birds actually enjoy taking baths. At least once a week you should provide your bird with access to water so that he can splash around and bathe if he wants to.
Most birds have fun getting wet and consider it a wonderful game.
There are various bird baths on the market that you can buy. A shallow bowl of water also works well for smaller birds. Many birds even like to accompany their owners into the shower, as long as the water pressure isn't too strong. Standing off to the side in the shower can help lessen the water pressure for Polly. And as long as the bird is healthy, showering with him essentially poses no health risk to the owner.
