Abstract
Abstract
In this study we document two records related to potential food opportunism in crab-eating fox, Cerdocyon thous. The records were made in Itapuã State Park, Viamão, RS, Brazil, and were obtained through camera traps. These showed individuals of C. thous carrying a brown howler monkey and an unidentified fish, both already lifeless. There are no records of howler monkey consumption by this species of carnivore, and fish are considered as unusual taxa in its diet. We assume that the captures occurred with the animals already dead, illustrating the food opportunism of the species and the potential occurrence of scavenging by this canid.
