Infant-carrying behaviour was observed in two families of captive golden-headed lion tamarins. Although the young were raised in almost identical social situations, we found a reversed involvement of mother-father pairs in the amount of time they carried their offspring. In one case, the parental division of carrying behaviour was consistent with the standard description for callitrichids in that the adult male was the primary carrier. In the other family, the mother carried the infant considerably more than the male. Comparison of transfer initiations and transfer times showed that maternal choice operated. It is suggested that maternal behavior may depend primarily on the female's physical and hormonal condition.
在两个圈养的金头狮狨家庭中观察到了携带幼崽的行为。尽管幼崽在几乎相同的社会环境中长大，但我们发现父母对在携带后代的时间分配上存在相反的情况。在一个案例中，携带行为的父母分工与绢毛猴科的标准描述一致，即成年雄性是主要携带者。在另一个家庭中，母亲携带幼崽的时间比雄性多得多。对转移起始和转移时间的比较表明存在母亲的选择作用。有人认为，母亲的行为可能主要取决于雌性的身体和激素状况。
