Hummingbirds - jewels of the sky

The fascinating family of hummingbirds is found exclusively on the American continent. The smallest, lightest and most colorful birds on earth belong to this family. Hummingbirds are real flight acrobats and can hover with an unbelievable 50 wing beats per second on the spot and even fly backwards. Hummingbirds feed mainly on flower nectar and prefer to fly to red and yellow flowers. Photographers from the picture agency BIA - birdimagency captured these moments for you with their cameras. The editors have selected this calendar for the CALVENDO Gold Edition.
