ABSTRACT

The short-eared dog (Atelocynus microtis) is one of the least known canids of the world. Essential aspects of its ecology, activity patterns and feeding habits remain unknown. To study the composition, behavior and interactions of the western Amazonian scavenger community, a baited camera-trapping survey was performed from August to September 2018 in the surroundings of the Tiputini Biodiversity Station (Yasuní Biosphere Reserve, Ecuador). A total of 12 camera stations were set up, employing cow heads acquired from local meat processors as bait. Short-eared dogs were captured by camera-traps, and two individuals showed interest in the carrion, providing the first evidence that short-eared dogs include scavenging as part of their foraging behavior. Detection of short-eared dogs in the area was surprisingly frequent, despite the short survey period, indicating that use of baited camera-traps can be an effective tool for the study of the short-eared dog, an elusive and poorly documented species.

摘要

短耳犬（Atelocynus microtis) 是世界上最不为人知的犬科动物之一。其生态学、活动模式和摄食习惯的基本方面仍然未知。为了研究亚马逊西部食腐动物群落的组成、行为和相互作用，于 2018 年 8 月至 9 月在 Tiputini 生物多样性站（厄瓜多尔亚苏尼生物圈保护区）周围进行了诱捕相机调查。总共设置了 12 个摄像头，使用从当地肉类加工商处购买的牛头作为诱饵。短耳犬被照相机捕捉到，两个人对腐肉表现出兴趣，提供了第一个证据表明短耳犬将拾荒作为其觅食行为的一部分。尽管调查时间很短，但该地区短耳犬的检测出奇地频繁，
