Abstract
Long-call vocalizations have been hypothesized to serve as communicative si gnals both within and between tamarin species. Prior evidence for the use o f long calls as interspecific signals, however, is based solely on observat ions of apparent countercalling between species. I conducted playback exper iments with groups of wild saddle-back tamarins, Saguinus fuscicollis, and emperor tamarins, S. imperator, to test the hypothesis that long calls func tion as interspecific signals between tamarin species forming polyspecific associations. Results show that in the absence of any other external cues, lone groups of saddle-back tamarins and emperor tamarins respond to the pla yback of long calls from both conspecific group members and heterospecific tamarins with which they associate. Playback of long calls from heterospeci fic tamarins elicited long calls and approaches towards the speaker. These findings are consistent with the hypothesis that long calls serve as inters pecific signals between associating tamarin species. (C) 2001 The Associati on for the Study of Animal Behaviour.
