长期行为研究需要对个体进行永久识别。对于性单态物种来说，个体识别的需要更为重要，因为现场观察者甚至无法区分性别。猫头鹰猴（Aotus spp.）是栖息在中美洲和南美洲森林中的性单形灵长类动物。我们在这里报告用于捕获、标记和识别阿根廷福尔摩沙东部猫头鹰猴（Aotus azarai azarai）个体的方法和药物剂量。我们使用吹管或二氧化碳步枪成功捕获了 70 只猫头鹰猴，但尝试用诱饵陷阱捕获它们却没有成功。在标记和项圈过程中，我们平均给每个人注射了总共 50 毫克的盐酸氯胺酮，包括飞镖中的剂量。为了标记它们，我们冻结了它们尾巴的一部分，并给它们安装了无线电或珠圈。在捕获或标记人员时没有造成死亡或危及生命的伤害。我们描述的程序应该允许人们在不可能诱捕时安全地捕获和标记小型树栖灵长类动物。
Long-term behavioral studies require the permanent identification of individuals. The need for individual identification is even more crucial for sexually monomorphic species since not even the sexes can be differentiated by the field observer. Owl monkeys (Aotus spp.) are sexually monomorphic primates inhabiting the forests of Central and South America. We report here on the methods and drug dosages used to capture, mark, and identify individual owl monkeys (Aotus azarai azarai) in Eastern Formosa, Argentina. We successfully captured 70 owl monkeys using blowpipes or a CO2 rifle, but attempts to capture them with baited traps proved unsuccessful. During the marking and collaring procedures, we gave individuals on average a total of 50 mg of ketamine hydrochloride, including the dose in the dart. To mark them, we freeze-branded portions of their tails and fitted them with radio or bead collars. There was no death or physical life-threatening injury while capturing or marking individuals. The procedures we describe should allow one to safely capture and to mark small arboreal primates when trapping is not possible.
