Abstract: Analysis of the number, weight and volume of food items in the digestive tracts of 70 teiid lizards, Tupinambis teguixin, were obtained during spring-summer from areas neighbouring El Bagual Ecological Reserve in northeastern Argentina. The food items revealed the species to be a . widely-rang'.ng opportunistic omnivorous forager. Tupinambis consumed a large proportion of fruits, invertebrate and vertebrates. The species forages in both terrestrial and aquatic habitats, but no evidence was obtained for arboreal feeding habits. A sample of 27 to 49 digestive tracts is sufficient to reveal 80-90% of the prey types in the diet.
