Many birds naturally eat plants as part of their diet. Some birds will chew on and possibly consume plants in the course of playing. Birds left unsupervised out of their cage may easily encounter plants kept around the house and in the garden. It is important for owners to be aware of which plants are toxic to birds.

Few actual studies are available in regard to plant toxicity and birds, so we must extrapolate from information about harmful effects pertaining to other animal species, including humans.

The following list of indoor and outdoor plants is an attempt to catalogue the plants considered to be potentially toxic. Pot plants with milky sap should be avoided. If there is concern regarding specific plants not listed here, then consult your local veterinarian, Poisons Information Centre, your state or territory animal health service or a reputable plant nursery for more information. Some plants have been included on this list even if there is a remote possibility of concern.
