This great bird is a Colibri / hummingbird. The bird never perched on a branch when he eats. He continued fly in the same place while inserting its beak into a flower to suck nectar or eating tiny insects. When hummingbird finished eating, he pulled his beak while flying backwards. Flying backwards is done by rotating the direction of its wings. Great is not it? no other birds can be like that.
