How Hunting Owls Use Sound to “See” Under the Snow
The great grey owl basically has a sound cone for a face, which helps it hunt down voles burrowing through snow in the winter.
The owl’s large facial ruff, formed of dense feathers, helps amplify sound and funnel it towards his ears. Through half a meter of snow, the sound of scampering feet is inaudible to us. But not to him. With the help of a special acoustic camera equipped with 60 highly sensitive microphones, we can see what the owl is hearing.
The footage in this video is amazing — and so is the owl’s sense of hearing. A YouTube commenter says “Cat software in Bird hardware. Bad news for the Rodents.” You can watch a short video on the science behind owl hunting techniques and watch the whole episode this is from about how animals use sound (but only in Canada, it seems…VPN works fine tho).
The only problem with this video is that now I want two hours of just closeup footage of the owl’s face and it flying directly towards the camera. Those eyes! And its mid-flight loaf-of-white-bread-shaped body! I would also like the owl to be my friend.
BTW, this clip is from a show called The Nature of Things, which is a CBC nature series that’s been going since 1960. A good thing to have on your radar if you’re looking for well-produced science & nature programs.
