Lafeber's Tropical Fruit Nutri Berries Parrot: Nature knows best In the wild, there are certain foods a bird intuitively craves and seeks out; foods with sweet flavors, succulent flavors. Foods like pineapple, papaya and banana. And they're the very same flavors used to create Tropical Fruit NutriBerries. Together with other natural, wholesome ingredients like cracked corn, millet, peanuts, eggs and safflower. Tropical Frit Nutri Berries provides your bird with the foods nature intended.
