These birds are found. a majority in the tropics. Hummingbirds have spectacular moves of flights. They can fly in all directions, fly forward, backward and also upside down. The birds can hover for a long period of time during their flight.
Hummingbirds produce pleasant humming sounds when it hovers over the flowers for feeding. The humming sound is generated when the bird's wings beat. That's how it got its name 'Hummingbird' and scientists have discovered that the hummingbird's hum originated due to the pressure difference between the top and undersides of the wings. It's found that the primary source of the hum is the upward-lifting pressure difference.
Hummingbirds are migratory birds and the only bird that can fly backwards. They are amazing birds having long beaks and wings that help them to fly very fast. The bird can travel along for long periods and the smallest among the hummingbirds is the bee hummingbird.
