The fascinating family of hummingbirds is distributed exclusively across the American continent. The smallest, lightest and most colorful birds of the world belong to this family. Hummingbirds are real flying acrobats. With incredible 50 wing beats per second they are able to fly on the spot and even fly backwards. Hummingbirds mainly feed on nectar. They prefer red and yellow flowers. Photographers of the bird photo stock agency BIA - birdimagency have captured these moments for you with the camera.
