Green-crowned Brilliant (Heliodoxa jacula)

New World birds that constitute the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5–13 cm (3–5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm bee hummingbird , weighing less than a U.S. penny .
They are known as hummingbirds because of the humming sound created by their beating wings which flap at high frequencies audible to humans. They hover in mid-air at rapid wing flapping rates, typically around 50 times per second, [1] but possibly as high as 200 times per second, allowing them also to fly at speeds exceeding 15 m/s (54 km/h; 34 mph), [2] backwards or upside down. [3] [4]
Hummingbirds have the highest metabolism of any homeothermic animal. [5] 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.
