 It feeds on small fruits, seeds and insects.As other tinamous, the undulated tinamou is secretive, and more frequently heard than seen.The song, commonly given throughout the day, consists of a deep, three or four noted whistle, which has been described by the onomatopoetic "com-pra pan" ("buy bread" in Spanish) or "Eu sou jaó" ("I am Undulated Tinamou" in Portuguese).
