What is a common behavioral issue that tight handling of hawks might lead to?

Tight handling of hawks can lead to a potential for aggression because when a bird feels overly confined or restricted, it may become stressed and anxious. This can foster feelings of frustration and defensiveness, as the hawk may perceive tight handling as a threat to its comfort or safety. Over time, this behavioral issue can manifest as aggressive tendencies, which are undesirable for both falconers and the birds they work with.

In contrast, fear of hunters may arise from factors outside of handling, such as negative experiences with humans or hunting situations. Difficulty flying might result from physical issues or improper training rather than handling practices. A preference for solitude relates more to the bird's individual temperament, which can vary regardless of handling style. Hence, the peak concern with tight handling is the potential for aggression as a direct response to the stress and discomfort it creates.
