The bee hummingbird is the smallest bird alive
It weighs about two grams and its eggs are the size of coffee beans
The bee hummingbird lives only in Cuba and grows to about six centimetres, barely larger than a large insect. Its heart can beat more than twenty times a second at rest and far faster in flight, and it must feed almost constantly to fuel hovering. It is also the smallest warm-blooded animal known.
