In the wild, Budgerigars feed on grass seeds, eucalyptus leaves, buds and bark and a large variety of greens. It's important to note that parakeets are vegetarian by nature, and should never be fed meat, milk products or animal proteins, as their digestive system will not be able to process those foods.
