Lafeber's Tropical Fruit Nutri-Berries for macaw and cockatoos is a nutritious gourmet food formulated by avian nutritionists to meet your bird's dietary needs. Tropical Fruit Nutri-Berries offers high quality ingredients such as pineapple, papaya, mango, corn, peanuts, egg and millet to name a few. The inviting berry shape provides for essential beak exercise that turns mealtime into a fun eating experience. Nutri-Berries are made to be totally eaten, putting and end to the problem of picky eaters. Unlike seed mixes, which allow birds to pick only certain seeds, birds eat the entire nutritious berry. You may feed as a complete diet, use as a conversion diet or simply feed as a nutritious treat.
