====The peregrine falcon (falcon peregrinus), also known as the peregrine and historically as the "Duck Hawk" in North America is a cosmopolitan bird of prey in the family falconide. The Peregrine is renowned for its speed, reaching speeds of over 320 km/h during its characteristic hunting stoop, making it the fastest extant member of the animal kingdom.==== ====It is a large,crow-sized falcon, with a blue-gray back, barred white underparts, and a black head and "moustache". Experts recognize 17 to 19 subspecies which vary in appearance and range; there is disagreement over whether the distinctive Barbary Falcon is a subspecies or a distinct spieces. Typical of bird-eating raptors, all subspecies of //F. peregrinus,// including the nominate, are sexualy dimorphic, with females being considerably larger than males.====
