A falconer should attempt to train for which of the following factors?

When training a raptor, a falconer should consider a combination of factors that influence the bird's training and performance, and the correct choice emphasizes the importance of both sex and species. Different species of raptors have varied hunting styles, physical attributes, and behavioral traits that can affect their success in the field. For instance, hawks may be more suited for certain types of game compared to falcons.

Additionally, the sex of the raptor can impact its characteristics; male and female birds often exhibit differences in size, strength, and hunting approach. Females are typically larger and may tackle larger prey, while males may be more agile and adept at hunting smaller game. Understanding these differences helps a falconer select the most appropriate bird for their training goals and the specific hunting situation.

Considering only one factor, such as species or weight alone, does not provide a comprehensive approach necessary for successful training. This holistic perspective ensures that the falconer is well-prepared to nurture and develop the raptor's potential effectively. Therefore, training based on a combination of factors is crucial for achieving success in falconry.
