Calls emitted by newborn pups of Ctenomys pearsoni Lessa and Langguth, 1983 away from the nest were frequency modulated succesive notes. The notes were characterized by mean maximum frequency under 5165 Hz, with mean main frequency under 2155 Hz, and mean note duration under 0.165 s. Their possible function as contact or distress calls, resulting in recovering to the nest by the mother, is discussed.
