What does the term 'passager' describe?

The term 'passager' specifically refers to a wild hawk that is less than a year old. In falconry, this designation is important because passagers are often sought after for their youthful vigor and untamed nature, which can make them more suitable for training and hunting as they may still retain their natural instincts.

This age classification helps falconers understand the hawk's behavior, potential, and the level of training required. Understanding the developmental stage of a bird is crucial for successful falconry, as different ages can exhibit different temperaments and training responses.

In contrast, the other options refer to unrelated aspects of falconry or bird behavior, such as specific training techniques, bait types, or nesting behaviors, which do not correlate with the term 'passager.'
