What is the function of a catchpole in wildlife control?

The function of a catchpole in wildlife control is primarily to capture larger wild animals. A catchpole is designed with a noose or loop that can be tightened around the animal's body, allowing the operator to safely secure and handle the animal without causing harm. This tool is particularly useful for animals that may be too large or aggressive to handle directly, as it provides a means of capturing them from a safe distance. By using a catchpole, wildlife control operators can effectively manage situations involving larger species while minimizing stress to the animal and risk to the handler.

In contrast, the other options do not accurately reflect the specific use of a catchpole. For instance, catching mice typically requires different methods such as traps specifically designed for rodents. Additionally, keeping birds away from crops is generally handled through deterrents rather than capture techniques. Lastly, while a catchpole may hold an animal in place after capture, its primary design and function focus on the act of capturing rather than containment.
