Supplementary Data 5
Bird id number, position, time, velocity, acceleration, and wingbeat frequency at every time step for flock #5.
Supplementary Data 6
Bird id number, position, time, velocity, acceleration, and wingbeat frequency at every time step for flock #6.
Supplementary Data 7
Bird id number, position, time, velocity, acceleration, and wingbeat frequency at every time step for 307 isolated pairs (birds with id 1 & 2, 3 & 4, 5 & 6, and so on are from a single pair).
Supplementary Data 8
Text file that includes mean wingbeat frequency, flight speed, and local density (approximated by number of neighbors within a distance of 5 m from the focal bird) for paired and unpaired birds in six flocks as well as for birds flying alone.
