Identifying client types can be a fun and enlightening pastime. Like "Birding" the tools are simple. A pair of binoculars, a camera, and a log book are all that is needed. To get you started I have provided a list of some endangered species to begin with. Care should be taken not to approach too closely to some of these species. For example the Florid Rightwinger may well be armed to the teeth, and should not be riled while in it's nest. So have fun, and fill your log book.
