English: Predation and grouping. A group of foragers (black squares) scanning for food. A predator (large white square) approaches, but the foragers flee (turn white) when the predator is detected: the detecting forager flees and triggers all its group mates to flee. Scanning for food stops and all foragers wait “up a tree” until the predator has departed. Once all the foragers are safe, the predator ignores them and looks for new targets. In this case none are in view and it continues to move forward. Dark green is empty space, lighter green circles are food items. |
