Abstract
A bird toy for stimulating a foraging instinct by surrounding a treat on a platform on a main body with one or more substantially transparent rings rotatable and vertically slidable on the main body. In one or more rotative positions of the ring or rings turned by a pet bird, the ring or rings are allowed to shift vertically to make the treat accessible. A bottom platform allows a more difficult test, requiring the bird to lift the ring or rings to expose a treat on the bottom platform after rotating the rings to the correct position allowing the rings to be lifted.
