HummingbirdsBook - 2015
Hummingbirds are some of the most beautiful, tiniest birds in nature. They are the only creatures that can fly forward, backward, sideways--even upside down! Their hearts beat anywhere from 500 to 1200 times every minute; their wings flap as many as 80 times per second; and they breathe up to 600 times per minute.
