Location of field study: Canada Place, Vancouver British Columbia. The camera with tripod was placed along a promenade ledge, to be aligned with approaching scoters (a), where extent of camera placement is shown in red. Collective motion in the flocking location (b) was recorded from the overhead location (top view in (c)). A schematic diagram of the experimental setup is shown in (d)
