too cool!!!

Chickens have a great ability to keep their heads stable. Our bodies use a gyro-like mechanism in our ears which has 3 mutually orthogonal inertial measurement devices. Modern motion processors use something called an Inertial Measurement Unit (IMU). These devices provide movement data which can be used to compensate for the movement. Chickens apparently have the same type mechanism only with a higher update rate.

To illustrate, see the video below...
