                    Figure 17-20 • Moments before landing a cormorant
                    extends its feet forward, tips up, much as a water skier
                    lands a jump.

























                    Figure 17-21 • Cormorant maintains its position in heavy
                    hydraulics by using its feet as paddles and its partially
                    extended wings and tail as outriggers.

























                    Figure 17-22 • Cormorant begins a deep dive by
                    spreading and flexing its tail, followed by a powerful kick

                    of its feet, much as a whale shows its fl ukes.
