在相邻的3群橄榄狒狒(P.Anubis)中，所有的雄性都是从它们出生的群体中迁出的。有证据表明，近亲繁殖衰退的成本可能会超过转移到另一支部队的成本。不太可能是由于避免近亲交配而进行的迁徙，是由生殖活动高于平均水平的雄性迁徙到动情雌性比先前的部队更多的部队进行的。在部队之间的交锋中，移民(转移)男性的行为方式减少了自己部队中的女性与外来者的接触，并降低了新来的人加入部队的可能性。出生的雄性对另一支队伍的成员表现出兴趣。雄性显性与年龄密切相关，而在转移雄性中，生殖活动与显性有关。在出生的雄性中，优势度随着年龄的增长而增加，但生殖活动减少。出生的雄性没有为了获得发情的雌性而进行激烈的竞争，而是秘密交配。与出生的男性相比，女性更倾向于转移的男性，以及不可能成为自己父亲的男性而不是本来可以成为父亲的男性。
In 3 adjacent troops of olive baboons (P. anubis), all males emigrated from their natal troop. There is evidence that the costs of inbreeding depression may exceed those of transferring to another troop. Migrations which were unlikely to be due to the avoidance of inbreeding were made by males with above average reproductive activity into troops with more estrous females than the prior troop. During inter-troop encounters, immigrant (transferred) males acted in ways that reduced the contact of females of their own troop with outsiders and lowered the probability of newcomers joining the troop. Natal males showed interest in members of the other troop. Male dominance was strongly related to age, and in transferred males reproductive activity was related to dominance. In natal males dominance increased with age but reproductive activity decreased. Instead of engaging in aggressive competition for access to estrous females, natal males mated surreptitiously. Females showed a preference for transferred males over natal males, and for males who could not have been their father over males who could have been.
