The Foraging Capsule is a high impact polycarbonate plastic. 6 1/4" long, 2" wide at the top, 4 1/4" wide at the base.
A spring loaded platform in the base adds additional challenge for advanced foragers! Large or extra large birds may pull on the hook on the bottom to release treats into the bottom compartment. Birds will then have to retrieve them by pulling pieces through one of the four 1/4" by 1" slot openings!
