“…The male spectral tarsiers at this site were never aggressive to young infants as has been observed among captive populations of Bornean tarsiers [64,65]. However, the aggression observed among captive Bornean tarsiers may be an artifact of captivity as neither R.H. Crompton (personal comm.)…”

“…Instead, these studies have suggested that the infant's postnatal growth rate is correlated with the development of allocaretaking behavior in anthropoid primates. A preliminary examination of the growth rate in spectral tarsiers indicates that, like other tarsiers [36,41,63,64], they have a relatively rapid postnatal growth rate. The mean infant growth rate for 2 male spectral tarsier infants was approximately 0.43 g per day from birth through 9 weeks [36].…”

Allocare in a Nocturnal Primate: Data on the Spectral Tarsier, Tarsius spectrum

Non-maternal infant care in many of the small-bodied New World primate species has been hypothesized by some researchers to be related to the high infant/adult weight ratio found in these species. The spectral tarsier, Tarsius spectrum, an Old World primate, has one of the highest infant/adult weight ratios of any primate, with infants weighing between 20–33% of adult weight at birth. On the basis of the hypothesized relationship between allocare and the infant/adult weight ratio, it is predicted that the spectral tarsier will also exhibit extensive allocaretaking behaviour. The results of this study indicate that although spectral tarsiers show care by male and female subadults as well as adult males, it is extremely limited compared to the extensive allocaretaking behavior observed in New World primate species such as Aotus and Callicebus. Spectral tarsier subadult females provide substantially more allocare to infants than do subadult males or adult males. Female subadults were observed sharing food, transporting, grooming, playing, alarm calling, baby-sitting and maintaining physical contact with infants more than other age/sex classes. Although the amount of allocare exhibited by adult males and subadult males was much less than that exhibited by female subadults, the data suggest that adult and subadult male spectral tarsiers do play a small part in the care and socialization of the infant. Adult males and subadult males were both observed occasionally engaging in allocaretaking behaviors such as grooming and playing, as well as frequently patrolling and defending the territory’s boundaries. The results from this study suggest that although a high infant/adult weight ratio may be a prerequisite for selection to favor extensive allocare, it is not a causal factor. Additional research is needed in order to understand better the selective pressures involved and the costs and benefits of providing allocare to subadults and adult male spectral tarsiers.

Hand‐raising a spectral tarsier (Tarsius tarsier) at the Ueno Zoological Gardens

On February 10, 2008, a newborn male spectral tarsier (Tarsius tarsier) was found on the floor of the indoor exhibit room in the Small Mammal House of the Ueno Zoological Gardens. The dam showed no signs of providing maternal care and therefore we decided to hand-raise the infant. Its birth weight was 18.7 g. We placed the dam and infant in an incubator and gave 12.5-25% formula (for kittens), until the 145th day after birth. We limited the volume of formula intake to avoid excessive intake and to prevent diarrhea. For nutrition enrichment, we added a chicken liver homogenate to the formula 1-3 times per day. The infant was given a sunbath for 10 min on the 28th day. He showed no serious decline in health, except for diarrhea that occurred during the first few days after birth. He ate a small cricket for the first time on the 50th day and easily caught mealworms on his own on the 105th day. Gradual changes in feeding times, formula concentration, and the nutritionally enriched formula were essential for successfully hand-raising the tarsier.

“…While there have been significant gains in scientific knowledge about wild Tarsius syrichta in recent years [Neri-Arboleda, 2002;Dagosto et al, 2001], there has been little success in the development of captive breeding programs [Haring and Wright, 1989;Lewis, 1939;Cook, 1939].

Introducing an innovative semi‐captive environment for the Philippine tarsier (Tarsius syrichta)

2Philippine Tarsier Foundation, Bohol, PhilippinesIn response to demands for research, captive breeding, and tourism, a semicaptive environment was created for the Philippine tarsiers (Tarsius syrichta) in Corella, Bohol, Philippines. The 7600-m 2 enclosure was continuous with the surrounding habitat, and utilized a unique predator control fence design and a lighting system to attract nocturnal insects. During 2 years of observation, the locations of over 500 tarsier sleeping sites were recorded. Tarsiers were found to prefer dense, low-level vegetation in secondary forests, with perching sites averaging 2 m above the ground. Up to 10 tarsiers were observed within the enclosure at one time, which is a high density compared to densities based on home-range estimates for wild tarsiers in the vicinity of the study site. In addition, the tarsiers were observed to be more social than previously reported.
