Fig. 4. Inter-individual mean fraction of body weight supported during each
wingbeat of the turn (N=6 for each wingbeat). Fraction of body weight
supported was calculated by dividing the estimated mean upward force generated
each bird by its body weight. The overall average fraction supported was 0.89.
The fraction supported reaches a local minimum at the 0th wingbeat, the middle
wingbeat of the turn and also the one with the greatest average body roll.
