The answer is yes, but with a few caveats. First, potatoes should only make up part of your Conure's diet. They are a good source of carbohydrates, proteins, vitamins, and minerals. In addition, potatoes contain fiber which is essential for a bird's digestive system. However, it is vital to feed potatoes to birds in moderation. In addition, potatoes can be harmful if not cooked properly. Uncooked potatoes contain solanine, a toxin that can cause gastrointestinal upset in birds.
