Figure 1

Number of additional fragments collected by the first carriers in a transport chain after the first fragment was dropped or directly transferred. Black bars indicate foragers that returned to the nest with a fragment during the observation time. White bars indicate foragers that continued to forage and returned to the patch at the end of the observation time.
