Video of the GPS data of 5 vultures in a staggered release protocol (the release site is indicated by the yellow cross) for a single group flight. Individuals (indicated by colour) decided to leave one thermal (continued directional rotation in the track indicates periods where birds remained within a thermal) and glide to the next (indicated by the straight-line trajectories). Movement decisions during the glides were influenced by the social information provided by other individuals flying in the same airspace.
