Quick ID Guide to Southern African Animal Droppings

A quick and quirky ID guide to animal droppings for carnivores, primates, antelope, rats and mice, reptiles and birds. Photographs (mostly life-size) and brief text enable quick identification of the animals responsible for droppings. To confirm identity, summary tables give details of average width, length and typical contents of droppings. A recommended reference for local rangers and field guides, it will be of use to anyone with an interest in wildlife, and even to those who simply enjoy walking and observing in the wild.
