Why do kestrels hover in the air before catching their prey?

Kestrels hover in the air to gain a better vantage point and to locate potential prey on the ground. This behavior allows them to utilize their keen eyesight to spot small mammals and insects while maintaining stability in the air. The hovering also helps them to assess wind conditions and plan their approach for a more effective dive to catch their prey. Additionally, it conserves energy by allowing them to remain stationary while searching.
