Desert Bighorn Sheep, by Dale E. Toweill, Ph.D. 56 pages.

The abundance of information about its lifestyle and habitat presented in this book is enhanced by page after page of beautiful color photographs.
Counting Sheep: Twenty Ways of Seeing Desert Bighorn, edited by Gary Paul Nabhan. 261 pages. University of Arizona Press (July 1, 1993) Send a number of nature writers out into the same unrelenting stretch of Sonoran Desert. Then consider telling them to focus their attention on just one animal-Ovis canadensis, popularly called the desert bighorn or borrego cimarrón-and have them write about it. Have them write from makeshift blinds or from behind a gun barrel. Have them write while walking across the Cabeza Prieta at night, or while flying over it trying to radio-collar the creatures. Have them write from actual sightings of the animals or simply from their tracks and droppings. What would result from such an exercise is Counting Sheep, an unusual anthology that demonstrates the range of possibilities in nature writing.
