Stoop - there it is...The fastest animal on the planet in its hunting dive, the stoop, which involves soaring to a great height and then diving steeply at speeds commonly said to be over 320 km/h (199 mph), and hitting one wing of its prey so as not to harm itself on impact.
In 2005, Ken Franklin recorded a falcon stooping at a top speed of 389 km/h (242 mph).
