July 19 saw the launching of a new book describing the mammals of Jalisco’s Primavera Forest. “Mamíferos del Bosque La Primavera, Guía Ilustrada” (in Spanish) has 112 pages and 60 color photographs. The authors are three biologists, Silvia Zalapa, Edgar Godinez and Sergio Guerrero.
Several hundred friends of the forest gathered at the Librería Luis Martínez in Guadalajara to hear the authors describe the process by which they have succeeded in positively identifying 58 species of mammals living in the Bosque.
Five years ago, it was thought that only 38 kinds of mammals inhabit this pine and oak forest. Now, with the help of infrared cameras, animal-friendly box traps and even mist nets, Forest Service personnel have a much better idea who their guests are. Of course, as we may expect, there are deer, rabbits, skunks, foxes, raccoons, possums and plenty of mice. More surprising, we learn that the woods also house pumas, lynxes, armadillos, ringtails, white-nosed coatis, and a curious creature called the North American Least Shrew (Cryptotis parva) which is less than 10 centimeters long.
