Hummingbirds can fly upside down

Hummingbirds are tiny fliers that can flap their wings extremely fast – so fast in fact that they can hover. Not only that, the hummingbird can also fly up, down, sideways, backwards, and even upside down. The reason they can achieve such exceptional flight patterns is that they can rotate their wings in a circle, creating power on the upstroke as well as the downstroke. Hummingbirds use their unique ‘hands’, which are long bones at the end of their arms that support the wing. The wing itself is flexible at the shoulder but not at the wrist, helping the bird beat them fast without any bending.
