I think fruit ccan be a good part of a healthy eating birds diet. And if your bird is flighted and uses up a lot of its energy, fruit isnt that bad then. There are some super foods that are fruits. Berries and tropical fruits like mango and papaya,, coconut, poms, are very very healthy. I think the fruits like apples and pears and grapes can be fed lightly though. Too much sugar and not enough nutrients.
