As you may recall, I feed Peanut Lafeber's Nutri-berries by hand, for breakfast and dinner. Parrotlets are too small to tackle a whole "berry" by themselves, so it's a nice bonding event for human and bird. Originally, I started out just at dinner, but Peanut quickly Mind Controlled me into both meals. He's since Mind Controlled Bruce into feeding him sunflower seeds for lunch, but that's another story.
The berry is a selection of tasty hulled seeds, oat groats, peanut bits and pellets molded together in berry form, all stuck together with some sort of vitamin mixture. I hold the small, tasty Ball of Goodness while Peanut carefully bites tasty things from it. Sometimes, particularly by the end of the container, the berry gets too hard for his dainty bites, so I break it into smaller pieces for him. Invariably, we end up with small clumps of berry, and individual seeds. Even though it's all the same food, some days Peanut won't eat the kibbles, and other days he won't eat the little bits.
Before you go thinking my bird is too picky for words (not that I'd really blame you), think of this: Haven't you had days when you prefer chips over mashed? Canned over raw?
