Why do chicken heads stay still?
Unlike humans, chickens’ eyeballs don’t move in the eye socket. They’re fixed. So in order to shift their gaze, chickens have to move their whole head, and conversely, in order to focus on a fixed point, they have to keep their head completely still – even if their body is moving.
Why doesn’t a chicken’s head move when moving?
The nervous system is essential to body movement — without it, animals with brains could not move. Therefore, when a chicken’s head is cut off but the spinal cord and nervous system is left intact, the chicken can move around. But without a brain, it will soon stop moving, and never move again.
How do chickens stabilize their heads?
This is possible because of the vestibulo-ocular reflex, which uses rotation detectors in your inner ear, and the opto-kinetic reflex, which uses motion detectors in the retina of your eye. So instead, to keep the eyes still while the body moves, birds keep their entire head still.

How can chickens run without their heads?
Chickens definitely don’t keep their brain in their bum. But just like humans, they have special fibres called “nerves”, which run like tiny wires all through their body, and some of them end near the surface of the skin. These nerves are what can make a chicken keep moving, even after its head has been chopped off.
Why do birds heads move when walking?
The birds are simply moving their heads, allowing their vision to stabilize so their bodies can catch up, and then they’re on the move again. This happens so quickly, it appears as though they’re using a constant bobbing motion.
How do kestrels keep their head still?
