A 5-month field study on both the distribution and ecology of Callimico goeldii was carried out in the seasonally dry rain forest of north-western Bolivia. The species was found to be very sparsely distributed (approximately one group per 4 km2) in isolated groups of about 6 animals throughout the study area. Callimico was found to associate a great deal with two species of Saguinus that inhabit the same region in greater densities. It appears to be a habitat specialist, preferring low-lying and damp, but well-drained, bamboo forest and spending nearly all its time within 3 m of ground level, travelling mainly by vertical clinging and leaping. We believe that this ecological specialisation accounts for the species' discontinuous micro-distribution, and that this in turn is related to Callimico's distinctive pattern of social organisation.
在玻利维亚西北部季节性干旱雨林中，对歌伶猴的分布和生态进行了为期5个月的实地研究。在整个研究区域内，该物种分布极为稀疏（约每4平方公里有一个群体），每个孤立群体约有6只动物。研究发现，歌伶猴与同区域内密度较高的两种伶猴属物种有大量关联。它似乎是一种栖息地特化物种，偏爱地势低洼、潮湿但排水良好的竹林，几乎所有时间都在离地面3米以内活动，主要通过垂直攀爬和跳跃移动。我们认为，这种生态特化导致了该物种不连续的微观分布，而这反过来又与歌伶猴独特的社会组织模式有关。
