暴露在室外环境中的人类遗骸不仅会受到分解过程的影响，还会受到动物群的食腐活动的影响。动物群的食腐行为可能因地区和季节的不同而有很大差异，影响分解速度，更重要的是影响死后间隔估计的准确性。对于处理户外腐烂遗骸的执法人员和法医调查人员来说，必须全面了解当地环境中动物的食腐行为。这项研究的目的是确定西澳大利亚西南部地区腐烂遗骸的主要拾荒者。鸟类被认为是一系列以尸体组织和相关昆虫为食的鸟类、爬行动物、哺乳动物和两栖动物中的主要食腐动物。动物群的食腐行为随季节因素而变化，包括温度和降雨量。初步结果有助于对西澳大利亚西南部地区腐烂遗骸进行法医调查。
Human remains exposed to an outdoor environment are subject not only to the process of decomposition, but also to the activity of scavenging fauna. The scavenging behavior of fauna can vary considerably with region and season, affecting the rate of decomposition, and more importantly, the accuracy of postmortem interval estimations. A thorough knowledge of the scavenging behavior of fauna present in the local environment is imperative for law enforcement and forensic investigators dealing with decomposed remains located outdoors. This study was conducted to identify the major scavengers of decomposing remains in the southwest region of Western Australia. Avian species were identified as the dominant scavengers amongst a range of birds, reptiles, mammals, and amphibians feeding on cadaveric tissues and associated insects. The scavenging behavior of the fauna varied with seasonal factors, including temperature and rainfall. The preliminary results are useful for forensic investigations involving decomposed remains in the southwest region of Western Australia.
