Kestrel Stability

Short answer: Kestrels are small falcons famous for hovering while hunting.

According to the Reel, falcons get their flight stability from long, pointed wings that reduce drag for fast dives and precise maneuvers, a tail that acts like a rudder, stiff primary feathers for stability at speed and softer secondary feathers for lift. The footage, credited to lawrencechatton, shows a kestrel in flight.
