By filming ruby-throated hummingbirds ( Archilochus colubris) in flight, Hedrick showed that the birds invert their wings by twisting their wrists. “It looks like it’s affecting the whole wing because the bird’s skeleton is very compressed and its wrist isn’t very far from its shoulder,” says Hedrick.

In fact, they do it so much that if you ever spend time watching squirrels, you’ll quickly notice their tail is an essential part of their communication & survival strategy.

What is the aerodynamics of a hummingbird?

Science Graphic of the Week: Hummingbird Wing Aerodynamics. Hummingbirds don’t fly like other birds. Most wings work according to Bernoulli’s principle: Faster air rushing over the rounded topside tries to catch up with slower air on the flat bottom, creating low pressure on top that pulls the wing up.

How does a hummingbird generate its lift?

With the model, the scientists confirmed previous estimates that about 75 percent of the hummingbird’s lift is generated as the wings move forward, and the rest comes from the backward motion. The model also showed that other vortices spill from the wing’s tip and its trailing edge.
