Abstract

Within northwest Europe, especially the United Kingdom, the red fox (Vulpes vulpes) and the Eurasian Badger (Meles meles) are the largest wild scavengers capable of modifying a set of remains through scavenging. Knowledge of region-specific and species-typical scavenging behaviors of scavengers within the crime scene area and surroundings can aid in more efficient and accurate interpretations. The scavenging behaviors of captive and wild foxes and badgers were recorded and compared through actualistic methods and direct observation. The scavenging by wild foxes and badgers of surface-deposited baits and whole deer (Cervus nippon; Capreolus capreolus) in a woodland was observed and analyzed. Wild foxes were found to scavenge deer more frequently than badgers. The scavenging of deer remains by foxes was also compared with forensic cases. The scavenging pattern and recovery distances of deer and human remains scavenged by foxes were similar but were potentially affected by the condition and deposition of a body, and the presence of clothing.

摘要

在欧洲西北部,尤其是英国,赤狐(赤狐属)和欧亚獾是能够通过食腐改变一组遗骸的最大型野生食腐动物。了解犯罪现场区域及周边食腐动物的特定区域和物种典型食腐行为,有助于进行更高效、准确的解读。通过逼真模拟方法和直接观察,记录并比较了圈养狐狸和獾以及野生狐狸和獾的食腐行为。观察并分析了野生狐狸和獾在林地对地表放置诱饵和整只鹿(梅花鹿;狍)的食腐情况。发现野生狐狸比獾更频繁地食腐鹿类。还将狐狸对鹿遗骸的食腐情况与法医案例进行了比较。狐狸对鹿和人类遗骸的食腐模式及回收距离相似,但可能受尸体状况、放置情况以及衣物存在的影响。
