There may not seem a lot of point when flying forwards is so efficient and presumably much more useful. But, yes one species can – the humming-bird. These are tiny little birds. The bee humming-bird from Cuba is the world’s smallest bird. From beak to tail it is only 57 millimetres long. And it only weighs 1.6 grams.
Humming-birds get their name from the phenomenal speed at which they beat their wings. This is so fast that little birds can hover like a helicopter while drinking nectar from a flower. And their wing speed also lets them fly backwards when they feel like it.
