When is the use of a lure desired in falconry?

The use of a lure in falconry is integral across various training scenarios, which is why the correct choice encompasses all the listed instances. When a bird is being trained, the lure serves as a powerful tool to encourage the bird to fly, pursue, and eventually return, which establishes a strong foundation for its hunting instincts and recall abilities.

In situations demanding an immediate recall, the lure can effectively capture the bird's attention, prompting it to return swiftly to the falconer. This effectiveness grows even more pronounced when recalling a bird from great distances, as the lure can be visually stimulating enough to attract the bird's focus far away, facilitating a more reliable return even when it might otherwise choose to remain engaged in the environment.

Thus, the lure is not only essential during the training phases but also serves practical purposes in real-time flight management and recall scenarios, highlighting its multifaceted role in the practice of falconry.
