Over the past century, the Javan rhinoceroses' () secluded nature and low population size have led to a gap in knowledge of their ecology. With fewer than 80 individuals surviving in a single population in West Java, Indonesia, the Javan rhinoceros is one of the most critically endangered mammals in the world. As part of a pilot bioacoustics study of the Javan rhinoceros in 2019, we systematically reviewed camera trap footage from the core Javan rhinoceros range in Ujung Kulon National Park (UKNP). In doing so, we discovered a previously unknown interaction between the Javan rhinoceros and the slender-billed crow (), in which the crow finds and eats ectoparasites from the rhinoceros (Figure 1). We describe this interaction and suggest that it may represent a cleaning mutualism with benefits for both the crow and the rhinoceros.
在过去的一个世纪里,爪哇犀牛生性隐秘且种群数量稀少,这导致了我们对其生态的了解存在空白。印度尼西亚西爪哇仅有一个种群,存活个体不足80头,爪哇犀牛是世界上最濒危的哺乳动物之一。作为2019年爪哇犀牛生物声学试点研究的一部分,我们系统地审查了乌戎库隆国家公园(UKNP)爪哇犀牛核心分布区的相机陷阱拍摄的 footage 。在此过程中,我们发现了爪哇犀牛与细嘴乌鸦之间一种此前未知的互动,即乌鸦会从犀牛身上找到并吃掉体外寄生虫(图1)。我们描述了这种互动,并认为这可能代表了一种对乌鸦和犀牛都有益的清洁共生关系。
