| Abstract: | Saguinus fuscicollisproduces scent marks which consist mainly of a mixture of urine and the secretions of circumgenital scent glands. The present study investigates the ability of saddle-back tamarins to discriminate between scent material from conspecifics and corresponding material from other species and to differentiate material from two subspecies of Saguinus fuscicollis.When choices between urine samples from conspecifics and from guinea pigs and choices between urine samples from conspecifics and from common marmosets were offered, the tamarins investigated samples from conspecifics more frequently. Similar responses were obtained when choices between scent marks from saddle-back tamarins and from common marmosets and between scent marks from saddle-back and red-chested moustached tamarins were offered. The tamarins also discriminated between scent marks and between extracts of scent marks from Saguinus f. fuscicollisand Saguinus f. illigeri.In these choice tests, subjects of both subspecies tended preferentially to investigate material from Saguinus f. fuscicollis.The results of these studies show that urine and scent marks contain chemical cues on which recognition of conspecifics can be based. Moreover, the scent marks of closely related subspecies also offer cues which could enable the tamarins to discriminate between them. |
