Tamaño, composición y patrones diarios de actividad de grupos de pecarí de labios blancos (Tayassu pecari) en el Parque Nacional Mirador-Río Azul, Guatemala
Introduction: The white-lipped peccary is a highly social species that forms large, cohesive groups of 10 to over 300 individuals. They are vulnerable to human presence and habitat fragmentation because they require large extensions of undisturbed forest with sufficient availability of food to maintain their biological requirements. This species has disappeared in 84% of its historic range in Guatemala. In Guatemala, the only place containing a viable population of white-lipped peccary is the Maya Biosphere Reserve although it is possible that residual populations exist in Punta de Manabique Wildlife Refuge, Laguna Lachuá National Park and Maya Mountains Biosphere Reserve. The specific objectives of this study were to describe the size and composition of white-lipped peccary groups in Mirador-Rio Azul National Park, a protected area within the Maya Biosphere Reserve, and describe their daily activity patterns at waterholes using camera traps and direct observations. Methods: For analysis with camera traps we used photo-captures of white-lipped peccary obtained in a Rapid Ecological Assessment conducted in Mirador-Río Azul National Park in 2004. In addition, as part of this study, in 2006 we studied 12 waterholes, from April 22 to May 25. In 2007 direct observations were also made on waterholes from 8:00 at 17:00 during the months of February to May 2007 (dry season), and opportunistic encounters occurred on roads during June to January (rainy season). When a group was observed we recorded the date, time, number of newborns, juveniles and adults.
