A proper diet for a lovebird depends on if the bird is in captivity or in the wild. A lovebird survives on seeds, berries and fruits in the wild, while a lovebird in captivity may incorporate more grains and nuts into its diet.
A basic dry mix for a lovebird includes yellow millet, canary seed, white millet, peeled oats, buckwheat and linseed. Lovebirds can eat several kinds of fruit, particularly bananas, apples and pears. Lovebirds in captivity also eat many types of vegetables with a particular fondness for squashes. Mushrooms must be avoided, as the lovebird can not process the high level of oxalic acid in these foods.
