| Sumario: | Chacophrys pierottii is a medium-sized frog with generalist and opportunistic predation habits, and its diet includes mainly small vertebrates and arthropods. During a fieldtrip in Defensores del Chaco National Park (Alto Paraguay department, Paraguay), at the base of Cerro León we observed a juvenile male Chacophrys pierottii feeding on a juvenile Trachycephalus typhonius near to a temporary pond, formed by recent heavy rains. Our finding represents the first record of the arboreal frog, Trachycephalus typhonius as a prey item of C. pierottii. However, more data is necessary to determine if this event is an isolated case product of voracity, or T. typhonius juveniles on the ground are common prey during explosive reproduction. |
