During October 2002–December 2004, we determined presence of jaguars using three methods: we conducted interviews in local communities, collected scats, and installed automated-camera detection systems. Although no jaguar was mentioned in 86 interviews, three photographs of a male were obtained, and 10 of 132 scats were attributed to P. onca. This represents the first record of P. onca in central Mexico within the Balsas River macro-basin.

De octubre 2002 a diciembre 2004, evaluamos la presencia del jaguar usando tres métodos: condujimos entrevistas en comunidades locales, colectamos excrementos, e instalamos sistemas automáticos de detección fotográfica. Aunque en 86 entrevistas no se mencionaron jaguares, obtuvimos 3 fotografías de un macho y 10 de 132 excrementos fueron atribuibles a P. onca. Este representa el primer registro de P. onca en el centro de México dentro de la macrocuenca del río Balsas.
