Fig. 3. Representative strain recordings from different quail during take-off and horizontal flights. Comparison of smoothing routines: (A) interpolation and (B) Fourier smoothing. In B, the standard error is indicated by the green line. (C) Comparison of the strain trajectory for one individual quail during take-off and horizontal flights. Strain recordings from three quails during (D) vertical take-off flights and (E) horizontal flights.
