We report Bartlett’s Tinamou Crypturellus bartletti in Colombia, the northernmost documented species’ record. Based on passive acoustic sampling in the Caquetá-Putumayo (Japurá-Iça) interfluvial region, we detected an individual sound of this tinamou inside flooded forest (Varzéa) within La Paya National Natural Park. Our record adds a new species to the Colombian checklist, summing eighteen (18) species within Tinamidae for the country.
