Kestrels, close relatives of falcons, have very different "hunting tactics." While searching for prey, they hover as if suspended in the air. They spread their tails wide, enhancing their tail's ability to hold the air. They also lift the feathers at the tips of their wings, reducing the risk of losing balance due to air currents. The feathers at the tips of their wings are separated, creating small and rapid upward air currents to disperse any air gaps that may form on the upper surface of the wing. The kestrel uses this forward-pushing movement of the air to travel with the wind and hovers directly over the spot where it will land, watching for its prey.
