What are the top ten fastest birds in America?

Gentoo Penguin found on the Antarctic Islands can swim 40 km per hour. The peregrine falcon (Falco peregrinus) is the fastest living creature, reaching speeds of at least 124 mph and possibly as much as 168 mph when swooping from great heights during territorial displays or while catching pry birds in midair.

Despite its bulk, the ostrich can run at speeds of up to 45 mph if necessary.
