What is a primary reason for training a passage hawk?

Training a passage hawk focuses on the fact that these birds are typically younger and have spent some time in the wild before being trained. This experience in the natural environment can influence their behavior and adaptability. However, option A highlights the specific advantage that passage hawks may be easier to handle than adult birds or those that have been in captivity for a longer period. Since juvenile birds can be more accustomed to human interactions and training methods after their initial time in the wild, those qualities create an opportunity for falconers to more effectively train them for hunting and companionship.

The other options demonstrate various aspects of passage hawks that are beneficial, such as their wild experience and adaptability to captivity, but they are not singularly focused on the handling aspect, which is crucial for a falconer during training and subsequent hunts. Thus, while A speaks directly to the ease of handling, the nuances of the other options collectively contribute to the overall understanding of the advantages of training a passage hawk.
