What element is NOT a requirement for trapping raptors according to the general practices?

Using blocking techniques is not a universal requirement for trapping raptors. While such techniques can be beneficial in specific situations, they are not mandated as part of the general practices for trapping. The essence of trapping focuses on having a legal framework, including permits, preparation with tools like traps, and the use of suitable bait to attract birds.

Permits are crucial in ensuring compliance with wildlife regulations, reflecting the legal responsibilities that falconers must adhere to when trapping. A trap must also be ready and in good condition to ensure both the effectiveness of the trapping method and the welfare of the raptors. The use of appropriate bait is fundamental because it helps to entice the raptors to the trap, increasing the chances of a successful catch.

In contrast, while blocking techniques can be a strategic addition to trapping methods, they are not universally essential for the act of trapping itself.
