A couple of other interesting things about owls - they can’t move their eyes, which is why they have a few extra vertebrae that allow them to swing their heads around so far, and some owls have offset ears that allow them to calculate a glide path toward their prey, kind of similar to how aircraft use ILS to stay on a glide path for landing.
