No. Uncooked dry beans contain hemagglutinin, which is highly toxic to birds. Thoroughly cooked beans, on the other hand, are safe and healthy.
Keeper's noteCooked beans are a great protein source for parrots. Boil until fully soft, never just soak or sprout dry beans for feeding. Lentils and chickpeas follow the same rule: cooked, plain.
Why raw dry beans is dangerous for parrots
Raw and undercooked beans — especially kidney beans — contain hemagglutinin (phytohemagglutinin), a lectin that clumps red blood cells and is poisonous in tiny amounts. Soaking alone does not destroy it; only a full boil does.
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.
