* Parrots: Parrots are herbivores (they primarily eat plants). Their diet varies depending on the species, but generally includes fruits, seeds, nuts, and sometimes leaves and flowers. Some parrots might also eat small insects as a source of protein.
* Deer: Deer are also herbivores. Their diet consists of grasses, leaves, twigs, berries, and other plants. They may occasionally eat small insects or fungi, but their main food source is plants.
Therefore, parrots and deer both eat plants, but they are not known to eat animals.
