The feeding behavior and constriction pattern of adults and juveniles Oxyrhopus guibei Hoge & Romano, 1978 preying on rodents and lizards are described. An analysis of stomach contents of snakes preserved in collections was made to study its diet. The results indicate that this snake constricts prey with right to left side movements, horizontal position and with the dorsal portion of its body. Rodents were constricted by adult snakes whereas lizard were swallowed alive. The diet is composed of lizards and rodents, with an ontogenetic shift from lizards to rodents.
