Note – This post is only for a guideline. It is based on my experience and my research on parrots. Every parrot type is different from others, some may have a high level of tolerance to certain food and other may not. It’s always good to concern a proper vet if you are suspicious about some food as each food item can have the different level of effects on each parrot type. No legal responsibility is taken.
