Most African grey parrots and other kind of birds naturally eat plants as part of their diet. They will chew on and possibly consume plants in the course of play and curiosity. These Species are left unsupervised out of their cages may easily encounter plants kept around the house and in the garden.
Therefore, owners should be aware of which plants/ fruits are safe for their birds. Few actual studies are available concerning plant toxicity and birds. Some plants will just make a bird sick while others can kill them.
The following list of indoor and outdoor plants/ fruits have been reported as having no adverse effects on animals. Remember that any plant eaten in excess may be harmful or, at minimum, cause gastrointestinal upset. If you are concerned about the safety of specific plants not listed here, then consult your local animal Poison Control Center or your veterinarian for more information.
Safe Vegetables (Please make sure vegetables are well washed)
Beans, cooked only
Corn (milky & soft)
Eggplant (fruit only)
Pumpkin (and seeds)
Radish Red Beet (fresh)
Make sure you wash all vegetable thoroughly. If they contain seeds, remove them before giving it to your grey bird. If any vegetable needs pealing, better peal it and then offer it to your bird.
Safe Fruit (Please make sure vegetables are well washed)
Make sure that all seeds are removed before letting your grey bird eat the fresh fruits. And make sure you wash all fruits and vegetable thoroughly. Apple seeds contain a very small amount of cyanide, and if consumed in large quantities can majorly harm you or your parrot, I would suggest better to peal the apple before giving it to the bird.
Stay safe and much love !
