20 It is frequently easier to detect the tracks, droppings and other signs of many mammals than to see the animals themselves. However, great care must be taken in the interpretation of this indirect evidence. For example, a muntjac's tracks could be confused with those of a young fallow deer fawn at this time of the year. However, if droppings are also found, this may aid identification as a particular muntjac deer tends to deposit it's droppings in the same places and so heaps of droppings accumulate: such is not the case with the fallow. The search for footprints may show paths that are in regular use, and a fence may pick up identi- fiable hairs, such as the black and white guard hairs of badgers. Fresh soil heaped around the larger holes of badger setts or the smaller holes of rabbit warrens indicates active sites, as do fresh mole hills! Frayed trees rubbed by deer, pine cones eaten by squirrels, remnants of kills, shreds of fur, or half-eaten nuts, especially when found with tracks,all help in the detection of mammals, and often suggest suitable places to watch for animals. Two other useful ways of recording small mammals are searching for remains in discarded bottles and in pellets cast by owls. Remnants of skulls and teeth can, in most cases, be isolated and precisely identified. For the rather more experienced mammalogist, one of the accurate ways of recording small mammals is by the use of various traps that can be
