I don't like to feed them much grape because of the sugar either, Nanners, but I make a big sacrifice! I buy seeded grapes, but them in half, take the seeds out and dole them around to the birds, and then I eat the grapes! I'll give them a bit of the grape along with the seed, but not very much.
I give my birds raw garlic pieces in their chopped veggies, and they love it. Crystal is a fanatic when it comes to bird nutrition, and she told me to so I do! Mind you, it's not very pleasant being breathed on afterwards! lol
I'm going to go back and read this article tomorrow ... it looks very interesting!
