Dove feather, SEM

Dove feather. Coloured scanning electron micrograph (SEM) of a body (contour) feather from a dove (family Columbidae). Each barb (running from lower left to upper right) has an array of barbules running from either side of it. On one side of the barb, the barbules terminate in hooks (purple) that grab the hookless barbules protruding from the next barb. This structure allows contour feathers to be strong yet light and flexible to assist in flight. Magnification: x250 at 6x7cm size

Animal Body Barbs Barbules Bird Columbidae Dove Feather Feathers Keratin

EDITORS COMMENTS
This print showcases the intricate beauty of a dove feather in stunning detail. Captured using a scanning electron microscope (SEM), this coloured micrograph reveals the fascinating anatomy of a body feather from a member of the Columbidae family. The image depicts each barb, running diagonally across the frame, adorned with an array of delicate barbules extending from either side. What makes this structure truly remarkable is that on one side of each barb, these tiny barbules terminate in hooks, colored in vibrant purple. These hooks serve as ingenious mechanisms that firmly grasp onto hookless barbules protruding from the next adjacent barb. This unique arrangement allows contour feathers to possess exceptional strength while remaining lightweight and flexible – essential qualities for birds during flight. The magnification level used for this photograph was x250 at 6x7cm size, enabling us to appreciate every minute detail present on this mesmerizing dove feather. As we admire this extraordinary image captured by Science Photo Library, we gain insight into the intricate world of avian biology and marvel at nature's ingenuity displayed through keratin-based structures like feathers. This awe-inspiring photograph serves as a testament to both scientific discovery and artistic appreciation for our natural world.
