What is the best way to prevent an American Kestrel from carrying?

Using a weighted lure line is particularly effective in preventing an American Kestrel from carrying because it adds resistance that can deter the bird from taking off with the lure. When a kestrel is offered a lightweight lure, it may be inclined to carry it away, which can lead to issues such as not returning or becoming distracted. A weighted line creates a physical limit on how far and how effectively the bird can fly with the lure, helping to ensure that the falconer has better control during training or hunting.

Other methods, such as using a lightweight lure, may encourage the kestrel to try to take the lure, thereby potentially leading to carrying behaviors. Flying the bird only when it is in yarak (a state of readiness and focus) does not address the physical aspects of carrying; it relies more on the bird's mental state. Similarly, using a halsband, which is a type of restraint that goes around the bird’s neck, may limit its movement but does not actively prevent the bird from attempting to carry something if it were to get the opportunity. Thus, a weighted lure line stands out as the most direct method to prevent carrying.
