Occurred on March 28, 2018 Gainesville, Texas, USAbr br Info from Licensor: "I consult on animal training with zoos to improve animal welfare. We were training these two capybaras at the Frank Buck Zoo in Gainesville, Texas to a station. This means to stay in a certain area when asked. Capybaras enjoy food but they also enjoy being scratched, so we also use scratches as a reinforcer for this behavior. The back scratchers are extra effective as you can see. Capybaras are the largest species of rodent and are found in South America.
