“…The mean interbirth interval of 14.2 months (range ¼ 6.5-25 months) in the Callicebus groups is similar to that reported for two captive C. cupreus populations (13.1 months [Jantschke et al, 1995] and 11.9 months [Valeggia et al, 1999]) when the infant survived its first year or till the next birth. After the early death of an infant, however, the interbirth interval was significantly shorter in these two captive populations (8.8 mo [Jantschke et al, 1995] and 8.2 months [Valeggia et al, 1999]).…”

“…However, the fact that two of the four saki and titi individuals with the longest tenure are still alive means that these are necessarily underestimates, and the continuation of our research program should provide better estimates in the future. In captivity, both saki and titi monkeys have been reported to live, and remain reproductively active, until more than twice the age we have recorded thus far (C. cupreus, male: 22 years, female: 23 years [Jantschke et al, 1995]; P. pithecia, male: 28 years, female: 32 years [Becker et al, 2013]). …”

“…After the early death of an infant, however, the interbirth interval was significantly shorter in these two captive populations (8.8 mo [Jantschke et al, 1995] and 8.2 months [Valeggia et al, 1999]). The fact that females rapidly returned to ovarian cyclicity after the loss of a neonate does not suggest seasonal ovarian inactivity; rather, a birth peak (60%) in the winter months (December-March) in one of the captive populations was most probably due to an interbirth interval of approximately 1 year [Valeggia et al, 1999].…”

“…Additionally, another five saki and four titi secondary groups at the site have been monitored for shorter duration over the course of the study (Table I). Individuals of both species were classified as infants (0-6 months old), juveniles (6.1-24 months old), subadults (24.1-48 months old), or adults (>48 months old) based on ontogeny patterns and life history traits observed during this study (see Results) and those reported in the literature from captive populations of titis and sakis [Garber & Leigh, 1997;Jantschke et al, 1995;Savage et al, 1995;Valeggia et al, 1999;Waters, 1995] and from one group of wild sakis [Norconk, 2006[Norconk, , 2011.…”

We investigated demographic patterns and life history traits from several groups of red titi monkeys (Callicebus discolor) and equatorial sakis (Pithecia aequatorialis) monitored throughout the first 12 years (November 2003 through May 2015) of an ongoing research project in the Yasuní National Park and Biosphere Reserve, Ecuador. The saki groups ranged in size between two and six individuals, comprising either one adult male and one adult female or multiple adult-sized males or females, plus immatures. Deviations from a pair-living structure resulted when two different daughters of the resident female grew up and successfully reproduced in their natal group and when an adult-sized male temporarily immigrated into the group when it already contained an adult male. The titi groups also ranged in size between two and six individuals, but almost exclusively lived in groups with one adult individual of each sex. No titi offspring were observed to breed in their natal groups, and both male and female offspring dispersed when they were between 2.1 and 5.0 years old. In both titi and saki groups, vacant breeding positions resulting from the disappearance of an adult group member were promptly occupied by immigrants of the same sex as the disappeared group member. We recorded nine saki and 28 titi births. Eighty-three percent of the titi births occurred between September and January, suggesting reproductive seasonality. The mean interbirth interval after an infant survived its first 6 months was 21.3 ± SE 1.9 months (N = 3) for sakis and 14.5 ± SE 1.5 months (N = 14) for titis. Saki infant survival was 70%, and juvenile survival 57%. Titi infant survival was 88%, and juvenile survival was 53%. This 12-year study provides important insights into the functioning and maintenance of pair-living and social monogamy in two little-known platyrrhine species.

“…Generally, all group members participate in infant care, but the adult male owl monkey is the primary infant caregiver [1][2][3][6][7][8][9][10][11][12]. In contrast to other Neotropical primates living in small family groups, titi monkeys (Callicebus) and callitrichids, where the father starts to transport the infant(s) regularly from the first day of life [7,[13][14][15], as a rule the newborn owl monkey is carried nearly exclusively by its own mother [1-3, 6, 7, 9] in a distinctive ventrolateral position. This well-documented result does not exclude exceptions; either the father [8] or a sibling [9] may be the main carrier from the first day of life.…”

Reproductive biology of female titi monkeys (Callicebus moloch) in captivity

et al. 1999

Titi monkeys (Callicebus spp., Cebidae) are monogamous neotropical primates that live in family‐like groups typically consisting of an adult monogamous pair and one or two young. Knowledge about the reproductive biology of this genus is scanty. This study investigated the reproductive biology of female dusky titi monkeys (Callicebus moloch). An initial analysis characterized reproductive parameters of 32 females from a captive colony maintained for 23 years at the California Regional Primate Research Center (CRPRC). The colony records provided data on reproductive parameters such as interbirth intervals, seasonality, age at first pregnancy, and reproductive rate in captivity. Changes in urinary levels of estrone conjugates (E1C) and pregnanediol‐3alpha‐glucuronide (PdG) were used to characterize major reproductive events. Urine samples from eleven females were collected during 17 months. The endocrine data were used to examine changes associated with cycling, conception, and the post‐partum period as well as to determine the duration of the ovarian cycle and gestation length. The analysis of colony records indicated that females whose infant survived through weaning gave birth at intervals remarkably close to one year, while those who lost their offspring showed a significantly shorter interval. As long as they lived within the family group, mature female offspring did not breed. The analysis of the endocrine profiles indicated that after giving birth to a viable offspring, females undergo a relatively prolonged period of anovulation (approx. 6.5 months), followed by 1‐3 non‐conceptive cycles (approx. 1 month), after which they conceive and gestate (4.3 months).
