Weights of 15 pregnant and lactating females did not differ from weights of males, averaging 411-7 + 47-6 g but with a greater range of 327-535-2 g. The black fur of the forehead and sides of the head of Geoffroys Saddle-back Tamarins contrasts sharply with the predominantly buffy-orange agouti of the crown, extending to the mantle. Facial skin is black, and there are short gray hairs surrounding the mouth and sides of the nostrils. Outer sides of upper arms are darker than the mantle, and forearms and inner parts of arms are blackish. The saddle is well defined, striated, or marbled black, grayish, or buffy. The rump and thighs are reddish orange, similar to the mantle, and upper surfaces of hands and feet have black hairs. The chest is dark brown to black with occasional orange or reddish hairs. The tail is black, exceptfor the base, which is rufous. External genitalia are pigmented black.

Fruits eaten are largely drupes or arils of single or large number of small seeds. They are taken into the mouth whole, and the fibrous parts are spat out, either with seeds or alone. Drier mealy pulp is scraped off, and seeds are usually dropped. Geoffroys Saddle-back Tamarins are important seed dispersers. Seeds of 81 species are ingested and dispersed, including

As is typical of all saddle-back tamarins, Geoffroys Saddle-back Tamarins forage for animal prey mostly on vertical substrata (trunks and lianas) in crevices and knot holes, mostly (68% of the time) at heights below 5 m and occasionally stalking and picking through leaf litter on the ground.

There is no specific information available for this species, but aspects of reproduction and breeding are undoubtedly those of saddle-back tamarins in general. Ovarian cycles last 26 days. Gestation is 145-152 days, with interbirth intervals as short as six months. Females mature at about three months. Births can occur throughout the year but peak from November to February in the early to middle wet season. Infanticide was once observed in a group of Geoffroys Saddle-back Tamarins at the Quebrada Blanco—a case of a mother killing her newborn that had fallen several times on the day it was born and may have been wounded or born debilitated, with little likelihood of survival.

Groups of Geoffroys Saddle-back Tamarin are active for c.10-12 hours/day, beginning at ¢.06:00 h and entering sleeping sites at ¢.15:30-17:25 h.

, six groups averaged 6 ind/km* (range 3-6). In 62 groups counted at three other localities (Rio Maniti, Rio Tahuayo, and Rio Tapiche), average number of adults was 3-2 ind/group, with those besides the reproductive pair usually being males. Females leave their natal group at an earlier age than males. Geoffroys Saddle-back Tamarins at Quebrada Blanco occupy home ranges of ¢.40 ha, which overlap with other neighboring groups, and they travel c.1845 m/day. Encounters between groups are characterized by vigilance, vocal battles, chases, and physical combat, with both males and females participating. Aggressive behavior is coordinated among group members and directed mainly toward others of the same sex. Usually the group battles last ¢.25 minutes, but they can persist for as long as two hours. These encounters were usually at the locations of important feeding trees, and boundary areas not associated with these feeding trees were rarely defended. Success in defending the feeding tree was related to the size of the group. Geoffroys Saddle-back Tamarins form mixed-species groups with Spixs Mustached Tamarins. They sleep in separate sites but join up in the morning and spend ¢.82% of their time traveling together—Geoffroys Saddle-back Tamarins mostly in the understory and Spixs Mustached Tamarins mostly in the middle and lower canopy.

have minimal social interactions, with about one interaction noted for every five hours of observation. Most interactions were agonistic, with the dominant Spixs Mustached Tamarin displacing, threatening, and chasing away Geoffroys Saddle-back Tamarin from food sources, particularly when the canopy and number of available ripe fruits were small. The two species are known to groom each other in captivity, but this is evidently rare in wild groups. Geoftroys Saddle-back and Spixs Mustached tamarins at the Quebrada Blanco respond to their respective alarm calls, which are given at a rate of about one every two hours.

forage—cicadas in particularly at certain times of the year. Doubletoothed kites may follow groups of tamarins for more than two hours and are generally ignored; however, sometimes tamarins attempt to drive off a kite, and when it takes flight, the tamarins emit alarm calls. The rate of these alarm calls increases whenever kites follow tamarins. Similar but briefer associations have been observed with whitefronted nunbirds (Monasa morphoeus) and great jacamars (Jacamerops aureus). In most cases, alarms resulted in the tamarins moving down in the forest canopy or moving fast from the periphery of a tree to its trunk, but an (unsuccessful) attack by an ornate hawk-eagle (Spizaetus ornatus) caused the tamarins, exposed when feeding in the forest canopy, to literally fall out of the tree. The Guiana crested eagle (Morphnus guianensis) and the slate-colored hawk (Leucopternis schistacea) have been recorded as predators of Geoffroys Saddle-back and Spixs Mustached tamarins at the Quebrada Blanco. After a predator attack, both species remain nervous for several days, and rates of alarm calling are higher than usual; they also spend more time than is typical in the lower levels of the forest canopy. A group of Geoffroys Saddle-back Tamarins was seen to approach and mob (giving a specific trill call) two mating garden tree boas (
