We observed a birth in a group of Mexican mantled howler monkeys (Alouatta palliata) living under semi-free-ranging conditions on Agaltepec Island, Catemaco, Veracruz, Mexico. Although we could not quantify contractions, we were able to record a complete description of the sequence of events that resulted in a successful birth. Nine minutes passed from the release of the amniotic fluid to the total emergence of the infant. Although all group members were resting relatively close to the female when the birth occurred, none approached her until the postpartum period. Only then did several individuals briefly inspect the newborn and then resume their foraging activities.
我们观察到在墨西哥韦拉克鲁斯州卡特马科市阿加尔泰佩克岛半自由放养条件下生活的一群墨西哥鬃毛吼猴（Alouatta palliata）中有一只幼猴出生。尽管我们无法对宫缩进行量化，但我们能够完整记录导致成功分娩的一系列事件。从羊水破裂到幼猴完全娩出历时9分钟。分娩发生时，尽管所有群体成员都在离母猴相对较近的地方休息，但直到产后阶段才有个体靠近母猴。只有在那时，才有几只个体短暂查看了新生幼猴，然后又继续它们的觅食活动。
