Pelleted Bird Food Formulated diets actually come in the form of pellets, crumbles, or nuggets. They include Harrison's, Zupreem, and Roudybush. There are commercial foods for different species, so be sure to select the one appropriate for your bird. Some avian diets have higher fat levels that are suitable for many macaws and Golden conures, whereas others may be lower in fat and higher in protein to provide better nutrition for cockatoos and Amazons. Ask your veterinarian if you are unsure of which formulation to use.
It is often very helpful to buy small quantities of several brands and mix them together as you attempt converting the bird to the new diet. Some birds prefer large brightly colored pellets, while others do better with a formulated diet that is in very small pieces. You will need to work with your bird to find out which one(s) she likes.
