Document Summary
Callimicos engage more frequently in hind-limb dominated bounding along horizontal supports, and trunk-to-trunk leaping between vertical supports than tamarins: (cid:862)trunk-to-trunk(cid:863) = forelimb first landing pattern. Callimicos did not frequently eat exudates, nor did they search for arthropods on large vertical supports, thus callimicos were rarely seen clinging to vertical supports during foraging and feeding. Saddle-back and red-bellied tamarins are known to be territorial, with frequent intergroup encounters and border disputes among neighbouring groups. Activity budget provide one means of characterizing the amount of time a group or individual engages in different behaviors in order to compare energy expenditure among different animals, groups, or species. Callimicos, therefore, unlike the tamarins, do not actively defend their home range. In total, callimico group used at least 22 sleeping sites throughout its range during the study period. Locomotion: callimicos = trunk-to-trunk leaping, red-bellied tamarind = quadrupedal walking and running and branch-to-branch leaping.
