King-of-Saxony: Giant Head Wires | Cornell / National Geographic

March 12, 2018

The head wires of the King-of-Saxony are unlike any other feathers in the world. They’ve lost their normal feather structure and become a conspicuously awkward ornament. It may seem difficult to explain the evolution of head wires by the process of natural selection. In fact, they’ve evolved because of sexual selection—an extreme example of female mate choice affecting basic anatomy. Filmed and photographed by Tim Laman.

There are currently seventy-two short films in the entire Birds-of-Paradise Project playlist, ranging from 26 seconds to 8:29. In the upcoming weeks, we will present some of our favorites.

A film from the Cornell Lab of Ornithology. If no film or link appears in this email, go to the blog to view it by clicking on the blog title above. If the film stops & starts in an annoying manner, press pause (lower left double bars ||) to let it buffer and get ahead of you.  [Chuck Almdale]
