What is "rangle" in relation to hawks?

The correct understanding of "rangle" in relation to hawks refers to small stones fed to aid in digestion. This practice is essential in raptor care, as it can assist in the breakdown of food in the bird’s gizzard, effectively supporting the digestive process. Raptors naturally ingest small stones, known as gastroliths, which help grind food and contribute to their overall health.

The other options touch on different aspects of falconry and raptor care but do not accurately describe the term "rangle." Feeding raptors until they are full is an important part of their diet management but does not specifically define rangle. Feathers sorted with the beak relates to grooming behavior in birds but does not intersect with the concept of rangle. Lastly, a method of temporary release refers to specific training techniques or practices in falconry and does not encompass what rangle signifies. Understanding the definition of rangle as it relates to digestion highlights its role in maintaining the health and wellness of hawks.
