Have you ever noticed how some birds appear to constantly bob, tilt or jerk their heads as they move about? Shorebirds in particular are known for making distinctive “head throws” when alert to potential threats. These head movements serve to increase the amount of spatial information available to the birds’ eyes, which in many cases are relatively fixed in their sockets. By swiveling their heads (and with them their eyes), birds navigate their surroundings, locate food, and avoid predators. By
