I got this size pellets because I notice that my birds would bite into the course size, and 3/4 of it goes all over the bottom of the cage and I feel is very wasteful. This fine sized pellet is a good size because they pick up one or two at a time and is actually eaten. I have a pair of Solomon Island eclectus and an African grey. They don 't seem to mind the smaller size so that makes me happy. I also give other varieties of pellets cooked foods.
