Abstract

We quantified the food habits of the endangered blunt-nosed leopard lizard (Gambelia sila), an endemic species of the San Joaquin Valley, California. Based on analyses of stomach contents and prey remains in scats, we determined that this species is an opportunistic predator that eats large numbers of orthopterans, coleopterans, and hymenopterans, with dipterans, hemipterans, and lizards taken in lesser numbers. These data are similar to the qualitative or unpublished data of previous studies, and also are similar to the food habits of the congeneric Gambelia wislizenii. /// Cuantificamos los hábitos alimenticios de la lagartija leopardo narigona (Gambelia sila) clasificada en peligro, una especie endémica del Valle de San Joaquín, California. Basados en el análisis del contenido estomacal y restos de presas en heces, determinamos que esta especie es una depredadora oportunista que come muchos ortópteros, coleópteros, e himenópteras, con dípteras, hemípteros, y lagartijas en cantidades menores. Estos datos son semejantes a los datos cualitativos o no publicados de estudios previos, y son también semejantes a los hábitos alimenticios de la congénere Gambelia wislizenii.
