Different bird species require different diets and you can find premuim bird food designed for your particular bird. An optimal bird diet consists of formulated pellet diet and seeds and fruits along with a bit of animal protein (occasionally).
For optimal health, your bird needs carbohydrates, fats, proteins, vitamins and minerals.
You can buy fortified seed but a pelleted diet provides more complete and balanced nutrition and has the right balance of carbohydrates, fats, protein, vitamins and minerals in each bite. Seed mixes are great for bird food as long as they contain a variety of nuts, pellets, dried fruits and vegetables.
Your bird will love to have his food supplemented with fresh fruits and vegetables. Deeply pigmented fruits and vegetables have the most nutritional value and can be feed to the bird fresh or cooked. Make sure you either hang them or put them in the bowl and remove them after 3 hours to prevent spoiling. Don’t overdo it with the fruits and veggies, though too much can cause diarrhea.
