摘要

动物的工具使用传统上主要是在圈养灵长类动物中进行研究,因为这与人类进化有关。在此,我报告了一只自由放养的日本貂(Martes melampus)使用树皮和树枝的行为。这只日本貂把脸伸进一个装满水的容器中寻找东西,然后用嘴叼起树皮做舀水的动作。随后,它又用嘴叼起一根树枝,试图用树枝从水中舀东西。大约两周后,我在检查容器时发现了一只属于蚜蝇科的幼虫。虽然不清楚这只貂是否试图捕捉这只幼虫,但它的行为很像黑猩猩的伸手行为。利用树皮或树枝可能是一种优势,因为这样可以接触到难以触及位置的物体。

A possibility of tool use in a Japanese marten, Martes melampus

Tool use by animals, traditionally studied mainly in captive primates due to its relevance to human evolution, has been investigated in both free-ranging and captive mammals. Here, I present a report on tree bark and branch use behaviours by a free-ranging Japanese marten (Martes melampus). The marten put its face in a water-filled container, looking for something, and then it proceeded to make a scooping motion with a bark held in its mouth. Subsequently, it picked up a branch with its mouth and tried to scoop something from the water with it. Upon inspecting the container approximately 2 weeks later, I found a larva belonging to the family Syrphidae. While it is unclear if the marten was trying to catch this larva, its behaviour resembled reach extension behaviour seen in chimpanzees. The use of bark or branches may provide an advantage by allowing access to objects in hard-to-reach positions.

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
