The Energy Benefits of the Pantograph Wing Mechanism in Flapping Flight: Case Study of a Gull [PDF]

, 2015
Bird wings generally contain a 4-bar pantograph mechanism in the forearm that enables the wrist joint to be actuated from the elbow joint thus reducing the number of wing muscles and hence reducing the wing inertia and inertial drag.
