What is the significance of small stones provided to hawks, known as rangle?

Small stones, commonly referred to as rangle, are provided to hawks as an aid in digestion. This practice is rooted in the hawks’ natural behavior, where they would consume small stones in the wild to help break down food in their gizzards. The stones assist in grinding and digesting larger prey materials, enhancing the bird's ability to extract the necessary nutrients from its food.

The significance of this practice in falconry lies in promoting the health and well-being of the hawk. By ensuring that the bird has the right tools to aid its digestive process, falconers can help facilitate proper digestion, minimize the risk of health issues, and ultimately support the overall vigor of the bird.
