Call of nature - Richard Jones

Journey through the digestive systems of humans, farm and wild animals, and meet some of nature's ultimate recyclers as they eat, breed in and compete for dung. The fall of bodily waste onto the ground is the start of a race against the clock as a multitude of dung-feeders and scavengers consume this rich food source. From the enigmatic dung-rolling beetles to bat guano and giant elephant droppings, dung creates a miniature ecosystem to be explored by the aspiring dung watcher.

The author completes the book with an identification guide to dung itself, so that you can identify the animal that left it behind. Pellets or pats? Scats, spraints, frass, guano, spoor - learn your way around different species' droppings. There's also a dung-feeder's identification guide that includes the species you're most likely to encounter on an exploration of the dung heap.
