What does "cast gorge" mean in the context of falconry?

In the context of falconry, "cast gorge" refers to the act of a raptor vomiting. Raptors are known to regurgitate indigestible parts of their prey, such as bones or feathers, which they cannot process. This is a natural behavior that helps maintain the health of the bird by ensuring that it clears its digestive system of material that could cause obstruction. Understanding this behavior is important for falconers, as it can indicate the bird's health and feeding patterns.

The other options, while they involve behaviors or actions associated with raptors, do not accurately define "cast gorge." The action of a raptor flying high, a method of hunting, and the process of molting all pertain to different aspects of raptor behavior rather than the specific act of vomiting. Recognizing these distinctions helps falconers provide better care and management of their birds.
