Many common human foods are toxic to birdseven some that we consider healthy. Chocolate, for example, contains theobromine, a compound that can cause seizures and death in birds. Other foods that are poisonous to birds include avocado, onions, garlic, and grapes. If you’re unsure whether a particular food is safe for your bird, it’s best to err on the side of caution and avoid giving it to them.
It’s also important to be aware of the dangers of feeding birds moldy or spoiled food. Mold can produce toxins that can make birds sick, and spoiled food can attract bacteria that can cause illness. If you find moldy or spoiled food in your bird’s cage, be sure to remove it immediately and clean the cage thoroughly.
