Walking is perhaps one of the most difficult maneuvers a living creature can perform. And turkeys have highly evolved muscular and skeletal systems that support an efficient mode of locomotion: the trot.
Standing still, a turkey is in a state of stable equilibrium. Its center of gravity rests directly over its feet, with its muscles anchored to its skeleton, directing the turkey’s weight down below. While the turkey requires a small amount of energy to remain in balance, this is an efficient, low-energy posture.
But efficient, low-energy, stationary postures aren’t all that great for doing all the things a turkey likes to do, like searching for food, pecking at rivals, and escaping from predators. Doing any of these requires locomotion, which is a surprisingly complex and tricky task.
