Do you know what is the smallest bird in the world?

 

           Hummingbird is the smallest bird in the world. Hummingbirds are birds that comprise the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5cm-13cm (3-5 in range). They are also the only group of birds with the ability to fly backwards. Their English name derives from the humming sound made by the very fast beating of their wings. They can fly at speeds exceeding 15m/s (546m/h; 34mph). Hummingbirds drink nectar, a sweet liquid inside certain flowers.
