Movie S3 from from Evangelista, Ray, Raja and Hedrick, 3D trajectories and network analyses of group behaviour within Chimney Swift flocks during approaches to the roost. Proc R Soc B 10.1098/rspb.2016.2602 from Three-dimensional trajectories and network analyses of group behaviour within chimney swift flocks during approaches to the roost

This movie shows the bird positions in a reconstructed flock from an overhead view. The building outlines were added in the 3D animation package used to produce the movie, but were not included in any analysis routines. Three individual birds and their trajectories are marked by color; these are also shown in the camera view movie S2
