The Wingding Triangle Toy is just the toy to spark the interest of bored birds that have solved other complex foraging toys.  Can be used with the wing nuts on the bottom or top (easier).  Comes with treats (Nutriberries™) and spare parts.

An acrylic triangle lid and base sandwich the clear treat dish.  The toy is held together with three stainless steel (SS) bolts and wing nuts.  Plastic mini-bolts, beads, and a pacifier add to the fun.

To make the toy easier, put the bolts upside down (with the wing nuts on top).  Gently tighten the wing nuts.  Don't over tighten the wing nuts or your could break the acrylic triangles.

Included spare parts: 2 SS bolts, 4 SS wing nuts, 2 beads (22mm), and 4 mini-bolts.  
Additional parts sold separately (click on links).
