Apparently the head tilt is a sound thing that helps them locate the position of sounds above/below them better. Humans are built different so we don’t need to do that to locate the source.
Or so I’ve heard. A real scientist is welcome to correct me.
Not only does it help with hearing, but with sight as well. Two eyes looking horizontally at an object produce a dataset for the brain to process, but the depth perception is constrained to working in the horizontal plane. Tilting the head expands this into the third dimension, providing a lot more for the brain to work with.
Huh? That doesn’t make sense. Depth perception is in the Z (depth) axis. It’s neither in the X (horizontal) or Y (vertical) axis. You get the exact same stereo vision depth perception regardless of the orientation of your eyes.
Imagine a triangle with your eyes and the subject at a distance as the points. This triangle can be rotated around the long axis without changing anything. Tilting your head does nothing for visual depth perception.
Humans have the same issue, we just don’t have that same instinct for whatever reason.
Location is determined by the time-of-flight difference in the sound wave between each ear. So if something hits your left ear first, you know that it’s coming from the left.
You obviously have never been near a tree with a singing bird in it. You can definitely tell that the sound comes from above. That’s because the shape of the outer portion of the ear somehow funnels the sound in a way that makes it possible for the brain to determine the origin of the sound.
Adding on to it, the structure/shape of our ears are also unique. So if anyone loses their ear and get an implant, it takes them some time before they can fully get accustomed to it

Not a scientist, but can confirm, I am built differently than a fox.
Can confirm. Am not a Scientist Fox.

You can’t do that when things are above/below.
