If you look at this video, you will see that the bird picks the strawberries to eat and nothing else. This is the same thing I observed with my birds - namely, when you give them a selection, they always pick the same thing. That's why I recommend giving one single fruit, one single veggie and one single leafy green - a different one - every day. Because, this way, they will end up eating a much larger range of produce than when you offer a 'salad'.
