Huddle behaviors.
On the X-axis, monkey individuals are divided into three groups: non-huddlers (n = 13), low huddlers (n = 14) and high huddlers (n = 4). The Y-axis displays the mean time spent in a huddle posture (s/h, seconds per hour). Thirteen monkeys never displayed huddling behavior and were designated as non-huddlers. The time spent in the huddle posture was used to divide the remaining 18 monkeys into two groups based on the mean value (mean = 159.32). Four monkeys spent more time in the huddle posture than the mean value and were designated as high huddlers, whereas the other fourteen monkeys were designated low huddlers.
