Why do hummingbirds beat their wings so fast?

Quick Answer
Rapid figure-eight wingbeats let hummingbirds hover in place to feed on nectar, generating lift on both the upstroke and downstroke.
The Full Story
Hummingbirds can rotate their wings at the shoulder, sweeping them in a figure-eight pattern. This produces lift on the downstroke (about 75%) and the upstroke (about 25%), unlike most birds. Many species beat their wings roughly 50–80 times per second, allowing them to hover at flowers. The feat requires enormous energy, so they feed every few minutes and can enter a deep, energy-saving torpor at night.
Key Facts
1.A hummingbird's heart can beat over 1,200 times per minute.
2.Hummingbirds are the only birds that can fly backwards in sustained flight.
3.The bee hummingbird of Cuba is the world's smallest bird, about 5–6 cm long.
