The black-fronted titi (Callicebus nigrifrons) is a species of titi, a type of New World monkey.
The black-fronted titi is a small diurnal primate. [1] The body of this primate is covered in grey to brown fur with black fur concentrated around the face, the tail is slightly orange in color. [2][3] Body weight ranges from 1 to 2 kilograms and the head to body length is around 270 to 450 millimeters.[2] This species does not exhibit sexual dimorphism. [3] Members of this species can live up to 12 years of age in captivity.[4]
Habitat and Distribution
[edit]The black-fronted titi is endemic to the Atlantic forest region of Brazil [5][6][2] and has a home range averaging 20 hectares.[6] The black-fronted titi is arboreal and prefers the middle to upper canopy of the forest.[3] However, it will move to the forest floor at times to forage, travel, and play.[4] Play behavior on the forest floor has been documented between black-fronted titis and marmosets in Brazil.[7]
Ecology
[edit]Diet
[edit]The diet of the black-fronted titi is frugivorous and they forage in dense vegetation.[3] They are also known to eat leaves, seeds, invertebrates, and flowers. [5][8][6] Due to their highly frugivorous diet, they play a key role in seed dispersion.[9]
Predation
[edit]Predators of the black-fronted titi include raptors, mammalian carnivores, snakes, and other primates.[3][1] Black-fronted titis are particularly vulnerable to raptor attacks when they move to the upper portion of the canopy to sunbathe on cold mornings.[3] After detecting a raptor black-fronted titis respond quickly using alarm calls and hiding.[3]
Behaviour
[edit]
The black-fronted titi is socially monogamous[10][3][2] and is typically found in a group of two to six individuals, which includes the adult pair and their offspring.[4][2] Females give birth to one offspring per year, usually in July or August.[11] Parental care and social activities with the offspring are carried out by the male of this species, while the female only provides milk.[11] Both males and females disperse from their natal group at three years of age. [4]
The black-fronted titi is territorial and will defend territories, food resources, and mates with loud calls individually or in duets or choruses.[6][4] Loud calls are used for within and between group communication and have a high amplitude and a low frequency which allows them to be heard over long distances.[12] Loud calls are broadcasted at dawn and when titis see or hear another group.[6] When confronted by a predator, duets and choruses can last up to two hours, with group members alternating between soft and loud calls. [13] There are no sex differences in calling behavior during predator interactions, both males and females will call. [3] The black-fronted titi can produce calls which encode the predator type (aerial or terrestrial) and predator location to nearby conspecifics.[14]
Characteristic of the Callicebinae family, black-fronted titis can be observed with interwoven tails, a behavior thought to reinforce pair bonds and strengthen social relationships.[15][16][17]
Conservation
[edit]The black-fronted titi is classified as near threatened by the IUCN due to extensive habitat loss, forest fragmentation, and an estimated population decline of more than 20% in the past 24 years.[4] Small, isolated populations are common due to fragmentation and in some areas this has led to the species going locally extinct.[2] Noise pollution can also negatively impact this species. One study found that noise from mining operations restricted the black-fronted titis long distance communication due to the overlap in frequency between mining noise and loud calls, this is significant for a species that relies heavily on vocal communication in social interactions.[6]
