To determine whether gibbons discriminate among songs given by different groups, I conducted a series of experimental playbacks of recorded Bornean gibbon (Hylobates muelleri)duets. The gibbons did not respond differentially to their own, neighbors’, and strangers’ songs. Failure to show vocal discrimination may be due to factors associated with the experimental procedure or may indicate that there is no selective advantage gained by responding differentially under the playback circumstances.
