The plot is similar to Fig. 7b and SI Movie 1, but it additionally shows the vertical speed distributions at different altitudes ranging from [z-50m; z+50m]. Altitude (z) is shown on the top, and can also be seen in the inset (at the bottom left). The inset shows the full trajectories of all birds (same data as on Fig. 7a) in the relative coordinate system (x, y, z) centered around the centre of the thermal.
