Animal scavenging on pig cadavers in the Lowveld of South Africa

Scavenging animals often scatter skeletal remains of forensic interest and leave bite marks. This study aimed to identify scavenging animals in the rural Lowveld of South Africa and to describe their scattering pattern and bite marks on bone. Ten pig cadavers (Sus scrofa domesticus) (40-80 kg) were placed at the Wits Rural Facility, Limpopo, South Africa during the summer and winter seasons. Motion activated cameras recorded the scavenging. Scavenger species were identified and their behaviors, scattering pattern, and bite marks were described. Scavenging was primarily by vultures (hooded, white-backed, and lappet-faced). Marabou stork, slender and banded mongoose, genet, civet, warthog and honey badger also actively sca-venged. Vultures began to scavenge the pig cadavers after 18hrs in summer and between 26 and 28 h in winter and skeletonized pig cadavers rapidly between 5 and 98 min. Skeletonization occurred more rapidly and diffusely in summer while winter cases were densely scattered. Overall the scattered remains were within an area of 157.9 m(2)/1705.5 ft(2) with a radius of 7.09 m/23.3 ft. Vultures cleaned bones thoroughly with very minimal markings -primarily nonspecific scores. The described scattering pattern and bite marks will assist in the recovery and analysis of scavenged remains. (C) 2021 Elsevier B.V. All rights reserved.

Automated summary

This study investigated scavenging animals in the rural Lowveld of South Africa by placing pig cadavers and observing their scattering pattern and bite marks. Vultures were the primary scavengers, with other animals like marabou stork, mongoose, genet, civet, warthog, and honey badger also actively participating. The results showed that scavenging behavior differed between summer and winter, with vultures cleaning bones thoroughly with minimal markings.
