Duck Hawk

The fastest animal on the planet, peregrine falcons achieve aerial dive speeds exceeding 320 km/h when stooping on prey, stunning or killing birds in flight with a blow from their feet.

Nearly extinct in North America and Europe from DDT poisoning in the 1960s–70s, peregrines recovered dramatically following pesticide bans and successful urban nesting programs.
