Joe Hutt is a passionate advocate for the mule deer, whose populations are vanishing from the rocky mountain west. This book tells of his life on a ranch in Wyoming, Over a period of many years, he and his wife got to know many members of a herd of mule deer, giving them names, and observing them from season to season, sometimes developing relations with the deer such that the deer approached them expecting to be groomed or to get a treat. I picked this book from a reference in a paper discussing the role of the lead female in herds of horses, and I was fascinated to learn more from Hutto's detailed observations. The end of the book is a cry against the disruption of mule deer habitat and the increasingly difficult conditions of their lives, including competition by elk and white tail deer. Growing up in Montana, mule deer seemed abundant. It is hard to imagine they are now endangered.
