Cotton-top tamarins are one of the most endangered species and these individuals are increasingly threatened by habitat destruction. Dr. Snowdon has developed a successful collaboration with INDERENA, the flora and fauna protection agency of Columbia, to study the behavior and biology of cotton- top tamarins in their natural environment. Although a wealth of knowledge is available about these small New World primates kept in captivity, little is known about their existence in the wild and their survival in the future is precarious at best. Since the utmost importance for the survival of any endangered species is that of reproduction, Dr. Snowdon will first use non-invasive techniques to obtain hormonal samples from animals in the native habitat. These findings will be compared with data obtained from groups of wild-caught tamarins housed in a captive, outdoor research facility to provide a better understanding of reproductive cycles and the influence of food distribution on seasonal breeding. Collaborating with a specialized team of Colombian biologists, Dr. Snowdon will gather information on infant development and examine where there are differences in development and infant care between wild and captive groups. Such information on yearly reproductive output and infant survival will be used in planning long-term conservation programs, in the development of conservation education projection and for scientific information that will generate new hypotheses and validate studies on tamarins raised in captivity. It is only through an understanding of the biology and behavior of this species, the establishment of protected reserves, effective conservation education programs, and public support that the survival of cotton-top tamarins will be guaranteed to have a future in the wild.

棉顶狨猴是最濒危的物种之一，这些个体日益受到栖息地破坏的威胁。 Snowdon 博士与哥伦比亚动植物保护机构 INDERENA 建立了成功的合作关系，研究棉顶狨猴在自然环境中的行为和生物学。 尽管人们对这些圈养的小型新世界灵长类动物有丰富的了解，但人们对它们在野外的存在知之甚少，它们未来的生存充其量也很不稳定。 由于任何濒危物种的生存最重要的是繁殖，斯诺登博士将首先使用非侵入性技术从原生栖息地的动物身上获取荷尔蒙样本。 这些发现将与圈养户外研究设施中的野生捕获狨猴群体获得的数据进行比较，以更好地了解生殖周期以及食物分配对季节性繁殖的影响。 斯诺登博士将与哥伦比亚生物学家组成的专业团队合作，收集有关婴儿发育的信息，并研究野生群体和圈养群体之间在发育和婴儿护理方面的差异。 有关年度繁殖产量和婴儿存活率的此类信息将用于规划长期保护计划、制定保护教育计划以及提供科学信息，从而产生新的假设并验证圈养狨猴的研究。 只有通过了解该物种的生物学和行为、建立保护区、有效的保护教育计划和公众支持，才能保证棉顶狟猴在野外的生存和未来。
