Extended Data Fig. 7: Flight paths of calling birds after call onset.

Spatial positions of calling birds relative to their spatial positions at call onset are shown in light grey for each individual, for all three dimensions, and for a time period of 209 ms (step widths: 41.5 ms) following the onset of Stack call emissions (Green: n = 60, Light blue: n = 16, Lilac: n = 9, Pink: n = 7, Orange: n = 1). Dark green line: median; light green area: interquartile range.
