Feather vane, light micrograph
Feather vane. Light micrograph of a part of a vane of a contour feather, from the wing of a bird. Each vane consists of several barbs (black) bearing barbules (thin, hair-like structures) with troughs on one side, which interlock with barbules with hooks on the neighbouring barb. This locks the barbs together, and makes the vane airtight and suitable for flight. The barbules of feathers occasionally become separated but they interlock again when the bird preens its plumage.

EDITORS COMMENTS
This print showcases the intricate beauty of a feather vane, captured under the lens of a light microscope. Taken from the wing of a bird, this image reveals the remarkable structure that enables flight in these magnificent creatures. The feather vane is composed of numerous barbs, depicted here in striking black. Each barb bears thin and hair-like structures called barbules, which possess troughs on one side. These barbules interlock with neighboring barbules that have tiny hooks, creating a mesh-like pattern that securely locks the entire vane together. This interlocking mechanism not only strengthens the feather but also ensures it remains airtight for optimal flight performance. In nature's design, occasional separation between barbules may occur; however, birds possess an innate ability to restore their plumage through preening. As they meticulously groom themselves, these separated barbules effortlessly reinterlock once again. With a magnification factor of x36 when printed at 10 centimeters across, this photograph provides us with an up-close look into the biomechanics and biological marvels present within avian anatomy. It serves as a testament to both the complexity and elegance found in even seemingly ordinary elements of our natural world. This stunning image captures not only the scientific significance but also highlights nature's awe-inspiring artistry within every contour feather.
