Feather follicles (blue) have tiny muscles (red) attached to them, so the bird can move each feather.

    Fascinating! I haven't had time to look it up myself. The structure reminds me of the muscle structure in human chins. That is quite cool! Nature is truly quite remarkable.

    Feathers are surprisingly fascinating. There are many different types to perform different functions. Their movement helps them hide, stay warm, flirt, hear, communicate, and I'm sure I'm forgetting things.

    Oh awesome, I didn't even think about the physical mechanism of their feather movement! This is really neat!

    It is really neat looking! I knew something existed, as I learned about the controlled movement from learning about owls' hearing and also how the ones with plumicorns (the "horns") moved them around like this tit's crest, but I had never looked for a photo before, so this was a lot of fun for me too.
