Hummingbird Aerodynamics of flight

Hummingbird flight has been studied intensively from an aerodynamic perspective. Some have referred to hummingbirds as more of an "extreme athlete" than other birds. One thing we all agree on is that they are a marvel to watch.

Writing in Nature, the biomechanist Douglas Warrick and coworkers studied the Rufous Hummingbird, Selasphorus rufus, in a wind tunnel using particle image velocimetry techniques and investigated the lift generated on the bird's upstroke and downstroke. They concluded that their subjects produced 75% of their weight support during the down-stroke and 25% during the up-stroke: many earlier studies had assumed (implicitly or explicitly) that lift was generated equally during the two phases of the wingbeat cycle, as is the case of insects of a similar size. This finding shows that hummingbirds' hovering is similar to, but distinct from, that of hovering insects such as the hawk moths. [6] The Giant Hummingbird's wings beat 8-10 beats per second, the wings of medium-sized hummingbirds beat about 20-25 beats per second and the smallest beat 70 beats per second.
