Hummingbirds Jewelled Messengers

Hummingbirds have become the greatest aerial acrobats on earth. They can hover, fly backwards and even fly backwards and upside down simultaneously. Plants have “created” hummingbirds as their messengers, carrying pollen from flower to flower. The smallest warm-blooded creatures on the planet, hummingbirds also have the highest metabolism of any vertebrate. The film explores the evolution of the birds, as they are shaped by their role as go-betweens for plants. These glittering birds live on the edge of what is possible, even going into a kind of hibernation each night, and all because of plants.
