They hover in mid-air by rapidly flapping their wings 12–80 times per second (depending on the species). They are known as hummingbirds because of the humming sound created by their beating wings, which flap at frequencies audible to humans. They also have among the highest metabolisms of any animal. To conserve energy when food is scarce, they have the ability to go into a hibernation-like state (torpor) where their metabolic rate is slowed to 1/15th of its normal rate. They can fly at speeds exceeding 54 km/h; they are also the only group of birds with the ability to hover backward. Trinidad and Tobago is known as The land of the hummingbird, and a hummingbird can be seen on that nations coat of arms and 1-cent coin as well as its national airline, Caribbean Airlines. -- Wikipedia.org.
