Made from high impact polycarbonate plastic for an extra long life. Measures 6 1/4" long, 2" wide at the top and 4 1/4" wide at the base. The Foraging Capsule has a spring loaded platform on the base which adds an additional challenge for advanced foragers! Birds may pull on the hook on the bottom to release treats into the bottom compartment. Your bird will then have to retrieve them by pulling pieces through one of the four 1/4" by 1" slot openings! Great for all medium and large parrots.
