WINGING IT AT THE HUMMINGBIRD HIGHLIGHTS OF 9 19 C
In today's post from 9 19C, I caught quite a few wing shots. Of course, wings have long been desired for humans, but we got arms instead! The wings birds have today are the same structure and feather arrangement of the ancient first bird, Archaeopteryx. The hummingbird performs a flying maneuver most other birds cannot do: hovering.
Here is a fact from Wikipedia: https://en.wikipedia.org/wiki/Bird_flight
Most birds that hover have high aspect ratio wings that are suited to low speed flying. One major exception to this are the hummingbirds, which are the most accomplished hoverers of all the birds. Hummingbird flight is different from other bird flight in that the wing is extended throughout the whole stroke, the stroke being a symmetrical figure of eight, with the wing producing lift on both the up- and down-stroke. Some hummingbirds can beat their wings 52 times a second, though others do so less frequently.
So, check out the wings! Enjoy!
