No. Chocolate contains theobromine and caffeine, both toxic to birds. The darker the chocolate, the more dangerous — but no amount is safe.
Keeper's noteThe biggest real-world risk is a parrot stealing a bite of a cookie, brownie, or hot-chocolate mug. Treat anything containing cocoa as off-limits.
Why chocolate is dangerous for parrots
Birds metabolize theobromine and caffeine far more slowly than humans. Even a small piece can cause vomiting, hyperactivity, tremors, seizures, and cardiac arrhythmia in a parrot. Dark and baking chocolate carry the highest doses, but milk chocolate and cocoa drinks are dangerous too.
My parrot already ate some — what now?
Remove all remaining food from the cage, note what and roughly how much was eaten, and call an avian vet or an animal poison control hotline immediately. Do not wait for symptoms — early treatment makes the difference.
