Fig. 10. The contribution of hydrodynamic forces to buoyancy offset during the
entire paddling cycle. Presented are the vertical components of hydrodynamic
lift from the body (blue line) and from the tail (black line) and the vertical
forces generated by the feet (green line), as calculated by the model
described in the text. Values are the means ±
S.E.M. of all birds (N=9). Also
shown is the average buoyancy estimated from measurements on the carcasses
(broken line). The net vertical force (red line) is calculated by subtracting
the value of the vertical hydrodynamic forces from the positive buoyancy of
the carcasses. The X axis is as described in
Fig. 2.
