Why are field jesses recommended while hunting your hawk?

Field jesses are recommended for use while hunting because they serve multiple protective functions for the hawk. One significant advantage is that they help prevent the bird from becoming entangled in trees or other natural obstacles during the hunt. This is crucial since a hawk in flight needs to navigate its surroundings without getting caught, which could lead to injuries or the inability to return to the falconer.

Additionally, field jesses also serve to keep the hawk from leaving the fist if it becomes startled or anxious. In the heat of the moment, an unexpected loud noise or rush of activity could cause a bird to inadvertently fly away, but with field jesses securely attached, the bird remains tethered and safe.

While there are various conditions and threats that field jesses address, their primary roles in preventing entanglement and ensuring the hawk remains with the falconer when startled are the reasons why they are an essential tool for safe and effective hunting. The other options may touch on aspects of bird care but do not encapsulate the comprehensive protective benefits provided by field jesses as effectively as the chosen answer.
