In a wild state, the food of this species consists of grass-seeds and various small berries, with which they pick up a large proportion of gravel to assist digestion. They are extremely fond of dusting themselves in the sand, lying down upon it for a long time, in the manner of Partridges and other Gallinaceous birds, to which indeed they are closely allied. Their flesh is excellent.
