Facts about Hummingbird Flight Mechanics

1. 06

   Hummingbird flight muscles make up roughly 25–30% of their total body mass, a proportion far greater than in other bird species.

   During torpor at night, hummingbirds dramatically lower their heart rate and body temperature to conserve the enormous energy spent on flight during the day.

   The metabolic rate of hovering hummingbirds is among the highest recorded for any vertebrate, requiring them to consume roughly half their body weight in sugar daily.

   Hummingbirds can rotate their wings at the shoulder in a figure-eight pattern, a unique skeletal adaptation that enables precise aerial maneuverability including backward flight.

   A hummingbird's wings can beat up to 80 times per second in some species, producing the distinctive humming sound that gives them their name.
