- Description: Hummingbirds are among the smallest of birds with most measuring 3 to 5 inches in length. The smallest being the 2 inch bee hummingbird weighing less than 0.09 oz. Their name comes from the humming sound created by their beating wings. They hover in mid-air by flapping their wings around 50 times per second. Hummingbirds have a very high metabolism To conserve energy when food is scarce, and nightly when not foraging, they go into torpor, similar to hibernation, slowing their metabolic rate to 1/15th of its normal rate.
