Birds can eat ripe tomato flesh in moderation, but the stems, leaves, and unripe green parts of the tomato plant must be avoided. Tomatoes belong to the nightshade family, and the green parts contain solanine and tomatine, glycoalkaloid compounds that are toxic to birds and can cause digestive upset, weakness, and in severe cases, cardiac problems.
Ripe red tomato flesh is safe and provides beneficial nutrients including vitamin C, vitamin A, lycopene, and hydration due to its high water content. Many parrots enjoy small pieces of cherry tomato or diced Roma tomato as an occasional treat.
When offering tomatoes, wash them thoroughly to remove pesticide residues, and remove the stem and any green portions completely. Cut tomatoes into appropriately sized pieces for your bird. Smaller birds like budgies and finches do best with tiny diced pieces, while larger parrots can handle bigger chunks.
Tomatoes are acidic, and some birds may develop irritation around the beak or mild digestive upset if they eat too much. Offer tomato as an occasional treat rather than a daily staple, perhaps once or twice a week in small amounts.
Avoid canned tomatoes, tomato sauce, ketchup, and tomato paste. These products typically contain added salt, sugar, preservatives, garlic, onion, or other seasonings that are harmful to birds. Only fresh, raw, ripe tomato should be offered.
Dried tomatoes are also not recommended, as they concentrate sugars and often contain sulfites or added salt. Sun-dried tomatoes packed in oil are especially problematic due to the high fat content.
As with any new food, introduce tomato gradually and watch for changes in droppings or behavior. If your bird shows signs of discomfort, discontinue tomato and consult your avian veterinarian.
