Abstract: | We present data on aspects of the behavioral ecology of a free- ranging group of Saguinus fuscicollis weddelliat a site in Brazilian Amazonia where a second callitrichid, Callithrix emiliae,is syntopic. Diet, activity patterns, and ranging behavior are broadly similar to those of S. fuscicollisfrom sites in Bolivia, Brazil, and Perú, though significant seasonal changes include an extreme and atypical form of ranging
behavior in which they foraged in central-place fashion around a source of exudate—Parkia pendula. S. f. weddelliwas active at relatively low levels in the forest both in absolute terms and relative to C.emiliae, which appears to be an important factor in their niche partitioning. Association between the two species appeared
to be less systematic overall than those observed between S. fuscicollisand congeners at other sites, though this may be partly a result of observation conditions. During the period of central-place
foraging, the two species exhibited a high degree of association. Other characteristics of the behavior of S. f. weddelliat the study site include the frequent use of tree holes as sleeping sites. |
