Picnic Trial 21 (VIDEO)
Caption
At the beginning of the video, we see a juvenile female next to the tree, the container, and the alpha female (F2) and the beta male (M3) next to the building. The distance between the building and the container is about 12 m. The provider (holding her infant) comes from the left side and quickly approaches the container. She opens it at 4 s. The juvenile female joins her at 5 s. The alpha male (M1), coming from behind the camera, joins her at 7 s. The provider retreats a little, checking where the alpha female is. As the latter is fast approaching, the provider leaves the container at 8 s. She had time to take five pieces of apple. When the angle of the camera widens, the alpha female is running toward the container, at the left of the tree. She arrives at the container at 12 s. In the background, one can see two other individuals running. The beta male joins at 19 s while the third-ranked adult female crosses in the background.
