86 reviewsBirds are talented fliers capable of vertical take-off and landing, navigating
turbulent air, and flying thousands of miles without rest. How is this possible? What
allows birds to exploit the aerial environment with such ease? In part, it may be because
bird wings are unlike any engineered wing. They are flexible, strong, lightweight, and
dynamically capable of changes in shape on a nearly instantaneous basis (Rayner, 1988;
Tobalske, 2007). Moreover, much of this change is passive, modulated only by changes
in airflow angle and velocity. Birds actively morph their wings and their feathers morph
passively in response to airflow to meet aerodynamic demands.
