Summarize this article:

Try one of the following recipes to provide food enrichment that will provide mental stimulation -- and fun! -- for your bird.  Punch a hole through a rice cake and hang from a string.  Parrot breeds especially enjoy pecking and foraging their way through this treat.  Fill a paper lunch sack with nuts, pellets, dried pasta, and/or dried fruit.  Tie the sack with a piece of ribbon or string and hang in your bird's cage.  Especially eager foragers might enjoy the challenge of a double-bagged sack.  Combine chopped walnuts, sunflower seeds, diced pears and apples, and granola and add enough honey and peanut butter to create a sticky mixture.  Slather a clean pine cone with the mixture, then roll in millet seeds.  Hang in your bird's cage.  This enrichment treat is especially popular with parakeets. Just as humans have preferences, your bird will gravitate toward particular flavors and textures.  While the list of treat recipes is almost endless, considering categories is helpful. Use your observations to craft homemade bird treats that will delight your pet. If your bird refuses to eat raw vegetables, try feeding it cooked versions.  Offer nutritious foods in different shapes.  Many birds enjoy peeling their own fruits and vegetables, so offer peas in the pod, oranges with rind, or apples with skin. Quinoa-based treats provide a wonderful source of avian nutrition.  Many pet lovers have developed recipes for "birdie bread"; a quick Web search will reveal a wide variety of options. Blend fruit mixtures with ice or fruit juice.  Human baby food is also a handy ingredient. Try mixing 1/2 cup sunflower seeds, 1 cup mixed walnuts and peanuts, 1/2 dried fruit, and 1 T. dry, hard corn kernels.  Store in a tightly sealed container in a cool, dry place.

Summary:
Use food for mental enrichment. Watch which foods attract your bird. Trick picky eaters by altering the shape or temperature of their food. Make grain-based treats for birds who are grain enthusiasts. Prepare smoothies and other fruit-based treats for birds who love sweet flavors. Assemble nut, seed, and dried-fruit treats to suit a variety of birds' needs.
