We love the Zip Chip trading disk for trading kestrels to tidbits. Whether you're trying to remedy a possessive behavior issue or you'd simply like to start a new kestrel with this method, the Zip Chip trading disc is the perfect little dish for placing your tidbits to keep them from getting lost on the ground or a trading mat. It's not long before the kestrel sees the disc appear from your hawking bag and knows the trade is coming. A real game changer for us here at Mountain State Falconry Supply. 
 
And bonus, you can also use the darn thing for its exact purpose. Learn to throw it up to 250' if you get bored and are looking for a new pastime.
