Scientists speculate that these bristles function in a manner similar to that of an animal’s whiskers, which is to transmit sensations of touch. Birds may benefit from the bristles’ ability to tell them their speed and direction in the sky. The bristles may aid non-avian birds in their search for insects on the ground.
