There are a variety of treats for parakeets–including sticks, berries and toppers, millet and an assortment of fruit and vegetables, such as bananas, zucchini, bell pepper, mango, peas and corn–that can be a delightful additive to your bird's diet. Do not feed birds avocado, fruit seeds, chocolate, caffeine or alcohol. Sugar and high fat treats should be avoided. Consult your veterinarian for a complete list of safe and non-safe foods for your parakeet.
