In the twenty-two years since the Awash baboon hybrid zone was first described, about 25-30 hamadryas or hamadryas-like hybrid males have taken up residence in anubis baboon groups. Most enter as mature adults, though some may immigrate as juvenile followers. Long-term tracking of known immigrants indicates that they may reside for four years or more in their adopted troop, during which time they establish a series of comparatively short-term harems, and probably sire hybrid offspring. "Abductions" of anubis females to hamadryas troops, as postulated by early observers, were not seen, though their occurrence cannot be ruled out. Younger, more recent immigrants tend to be "purer" hamadryas in phenotype, perhaps reflecting a more distant origin, or a change in the composition of neighboring hamadryas populations. Coexisting hamadryas and anubis show no signs of reproductive isolation by behavioral barriers, and evidently belong to a single "recognition species."
自阿瓦什狒狒杂交区首次被描述的22年以来，约有25 - 30只阿拉伯狒狒或类似阿拉伯狒狒的杂交雄性进入东非狒狒群体中生活。大多数以成年个体的身份进入，不过也有一些可能作为幼年跟随者迁入。对已知移民的长期追踪表明，它们可能在被收养的群体中生活四年或更长时间，在此期间，它们建立了一系列相对短期的妻妾群，并可能生育杂交后代。早期观察家推测的东非狒狒雌性被“绑架”到阿拉伯狒狒群体的情况并未出现，不过也不能排除这种情况的发生。较年轻、近期的移民在表型上往往更“纯正”地表现为阿拉伯狒狒，这或许反映了其起源更为遥远，或者相邻阿拉伯狒狒种群的组成发生了变化。共存的阿拉伯狒狒和东非狒狒没有表现出因行为障碍导致的生殖隔离迹象，显然属于单一的“识别物种”。
