In falconry how big should a tidbit be for kestrel?

In falconry, a tidbit is a small piece of meat or other food given to a bird of prey as a reward for good behavior or successful hunting. The size of a tidbit will vary depending on the size of the bird, but for a kestrel, a tidbit should be about 1/2 to 1 inch in size. It is important to not give kestrels too many tidbits, as this can lead to obesity and other health problems.
