What trait of the American Kestrel becomes a vice in falconry training?

In falconry, the trait of carrying is particularly significant because it can pose challenges during the training process. The American Kestrel, known for its agility and hunting skills, may sometimes exhibit the behavior of carrying, which involves the bird grabbing and holding onto prey or objects in its talons. This tendency can lead to difficulties if the bird becomes overly possessive or defensive about its catch, potentially disrupting training sessions or interactions with the falconer.

The ability to carry is essential for hunting but, in a training context, it can hinder the bird's willingness to return to the falconer or focus on commanded tasks. The falconer must manage this behavior appropriately to ensure that the bird understands when to relinquish prey and how to interact in a controlled manner. Consequently, while carrying is a natural and useful trait in the wild, it can become a vice in captivity if not addressed properly during training.
