FORAGING CAPSULE: This feeding device is for clever, experienced foragers. Grey Parrots, Amazons, Cockatoos, and Macaws will quickly learn to pull down the leather strapping to release food into the lower chamber where it can be retrieved. The bird must stand on one leg and hold the device steady with its other foot, before it can nibble away at the exposed food item. For filling the device, there is an opening at the top of the cylinder. You may use any dry food,but extruded pellets are one of the best choices.
