Why is the stability of the chicken head so good?

Years ago, camera manufacturers discovered the stability of chicken heads, and they used the principle of chicken heads to design stabilizers, including big-name manufacturers such as Fujifilm and LG, and even used the stability of chicken heads as a product advertisement. I have to bring this chicken to the sea.

The story stems from two brands: LG and Mercedes-Benz, which have recently released a "chicken-related" advertising video and are full of creativity. Yes, you are not mistaken.

The reason why LG and Mercedes advertised chickens is that the chicken head has excellent anti-shake ability, and the chicken head is always stable regardless of how the body twists. The only difference is that LG promotes the optical image stabilization (OIS) function of its latest flagship phone G2, while Mercedes-Benz hints at its own "Magic Body Control" system.

Not just chickens, many birds have this ability. It is generally believed that the stable head of birds is to maintain a stable line of sight. This is a very common phenomenon in the animal kingdom. When animals are in a certain visual environment, they tend to instinctively lock their center of vision at a certain point, or an object. If you try to turn around, you will find that your line of sight will not follow the head slowly, but will jump from a stable point to the next point.
