The Wild West may be a little wilder than you think. For thousands of years, jaguars roamed portions of Arizona, California, Arizona, New Mexico, Texas, and Louisiana, and sometimes ventured into Colorado, Oklahoma, Virginia, and North Carolina. But today, jaguars are mostly absent from the United States. American Jaguar: Big Cats, Biogeography, and Human Borders by wildlife biologist Elizabeth Webb takes a deep dive into the jaguar’s current predicament and highlights the work of field scientists searching for ways to restore their populations.
