Hummingbirds Can Fly Backwards

A hummingbird's wing doesn't just flap up and down — it rotates in a figure-eight pattern, generating lift on both the forward and backward stroke. This unique motion lets them hover motionless in mid-air and even fly backwards, something no other bird can do.

All that aerobatics comes at a cost. Hummingbirds have the fastest heart rate of any animal and must feed constantly, visiting hundreds of flowers a day. At night they enter a deep, energy-saving state called torpor, slowing their metabolism dramatically to survive until morning.
