Start simple, then make more difficult.
Place a piece of paper over the food dish so your pet bird has to knock it off to get food. Next, fasten the paper in place with masking tape.
Increase the difficulty. Gradually make foraging more difficult by using other foraging toys and hiding food in several locations.
Use several types of foraging each day for your pet bird.
Place a little dry food in the bottom of your pet bird's dish. Fill the dish with wood or plastic beads or smooth river stones. Sprinkle a little food on top and mix it in.
Hide food in easy-to-destroy containers such as paper cups, plain paper and dried cornhusks.
Place food in a paper cup (twisted closed) or other wrapper, and hang it from a lace, chain, skewer or quick link. [Safety Note: Use supervision with long chains or laces.]
Use durable or semi-durable containers to hide food. Make them or purchase foraging toys.
