Regrine falcons frequently grab prey birds from the air. sometimes they strike at high enough speeds that the force of the impact disables prey birds. a 480 g peregrine falcon high in the sky spies a 240 g pigeon some distance below. the falcon slows to a near stop, then goes into a dive--called a stoop--and picks up speed as she falls. the falcon reaches a vertical speed of 45 m/s before striking the pigeon, which we can assume is stationary. the falcon strikes the pigeon and grabs it in her talons. the collision between the birds lasts 0.015 s.
