  1. We do know now that flight came after the feather, and that the early stages of feathers were not aerodynamic. It’s only the most advanced stages in feather evolution that have that aerodynamic structure. But ultimately the result of all of this evolution is an incredible adaptation for flight. If you look at a bird’s wing, it has a particular shape that is similar to the shape you would see if you looked out the window of an airplane, and that is an airfoil-shaped wing with a curved upper surface that gives that wing a bit of extra lift in the air, and a bird wing has that shape just as an airplane wing does. But what’s amazing about a bird wing is that the individual flight feathers are also shaped like airfoils. …

    So what you get for a bird wing is an airfoil made up of airfoils and the bird has muscle control over all of those feathers, so it can constantly adapt and change the position of feathers and the shape of the wing to react to any change in air temperature, or wind direction, or air pressure, making it a truly incredible way to fly.

    Manukura- the little white kiwi

    Your post-4pm/pre-5pm pick me up. I wonder if birds, or animals for that matter, have any awareness of their cuteness.
