Overview
Coquerel’s sifaka (Propithecus coquereli) is a large, diurnal lemur native to the dry deciduous forests of northwestern Madagascar. Known for their remarkable leaping abilities, these primates can cover over 30 feet in a single bound, moving gracefully through the trees with their long limbs and powerful hind legs. Their distinctive appearance includes white fur, chestnut-brown patches on their arms, thighs, and back, and a black face framed by white fur. Coquerel’s sifakas are social animals that live in small family groups, typically consisting of two to eight individuals.
These sifakas are primarily arboreal, spending most of their time in trees, where they feed on a diet consisting mostly of leaves, fruits, flowers, and bark. They are folivores but also exhibit some frugivorous tendencies, especially when fruit is abundant. Coquerel’s sifakas play an important role in their ecosystem as seed dispersers, aiding forest regeneration. Their home ranges are well-defined, and group members communicate with one another using a variety of vocalizations, including their distinctive “shi-fak” alarm call, which gives the species its name.
Coquerel’s sifakas exhibit a matriarchal social structure, with females generally dominating males in group hierarchies. The species is known for its low reproductive rate, with females giving birth to a single offspring every two years. Infants cling to their mothers for the first few months of life before gradually becoming more independent. Habitat loss due to deforestation and agricultural expansion poses a significant threat to Coquerel’s sifakas, contributing to their declining populations in the wild.

Current distribution:
Coquerel's sifakas are found only in the northwestern part of Madagascar, specifically in Mahajanga and Boeny. Their range includes primary and secondary dry deciduous forests threatened by ongoing deforestation and habitat degradation. Protected areas, such as Ankarafantsika National Park, are vital for the species' survival, as they provide a refuge from human encroachment. Outside of these protected areas, sifakas face habitat loss challenges, which reduces food and shelter availability.
Human activities, including slash-and-burn agriculture, logging, and cattle grazing, have significantly reduced their natural range. As a result, the species is becoming increasingly confined to isolated forest fragments, making population connectivity difficult and increasing their vulnerability to local extinction. Despite these challenges, some populations remain stable in remote and protected regions. Conservation programs are essential to maintaining healthy populations in the wild and preventing further range reductions.
Physical Description:
Coquerel’s sifaka has a striking appearance, with mostly white fur covering its body, while the arms, thighs, and back are adorned with rich chestnut-brown patches. Its face is black and hairless, framed by a “halo” of white fur, and the eyes are large and round, which helps with vision in its forested habitat. Sifakas have long, powerful hind limbs and relatively shorter arms, which make them incredibly adept at leaping from tree to tree in search of food. While not prehensile, their long tails are used for balance during their agile movements.
Adults of this species can reach 18 to 22 inches (45 to 55 cm) with an additional tail length of 16 to 20 inches (40 to 50 cm). The average weight of Coquerel’s sifaka is between 7.7 and 9 pounds (3.5 to 4.3 kg), with males and females being similar in size. Their hands and feet are well-adapted for grasping tree branches, featuring large, opposable thumbs and flexible toes. The species’ distinctive posture—upright while clinging to tree trunks and vertical leaping between trees—sets it apart from other lemurs that rely more on quadrupedal movement.

Native Habitat:
Coquerel’s sifaka is native to the dry deciduous forests of northwestern Madagascar, where it inhabits primary and secondary forests. These forests are characterized by distinct wet and dry seasons, and the sifakas have adapted to the seasonal availability of resources. They prefer areas with dense tree cover that allows them to move easily through the canopy, as they are predominantly arboreal and rely on trees for food, shelter, and protection from predators. The trees also provide critical basking spots for thermoregulation in the early morning sun.
Though primarily arboreal, Coquerel’s sifakas are also known to occasionally come down to the ground to travel between trees when necessary, using a distinctive hopping gait while keeping their arms raised for balance. Their habitats are often fragmented due to agricultural activities and logging, limiting their range and making them more vulnerable to predators when on the ground. The species is primarily found in protected areas such as the Ankarafantsika National Park, where conservation efforts are in place to protect the remaining forest habitats.

Diet & Feeding Habits:
Coquerel’s sifakas are primarily folivores, meaning their diet consists mainly of leaves. However, depending on seasonal availability, they are known to consume a variety of plant matter, including flowers, fruits, seeds, and bark. During the dry season, when leaves are scarce, they rely more heavily on tougher vegetation like bark and stems, which they can digest thanks to their specialized digestive systems. Their diet provides moisture and nutrients, reducing the need to seek out water sources regularly.
Foraging typically occurs in the morning and late afternoon when temperatures are cooler, and their feeding patterns vary according to what plants are in season. Coquerel’s sifakas also play a critical role in seed dispersal, as they consume fruit and later defecate the seeds in different parts of the forest, promoting plant diversity. Though they can digest a wide range of plant material, habitat destruction limits food availability, contributing to the species’ vulnerability. They may spend up to 40% of their day foraging for food.
Mating Behavior:
Mating Description:
Coquerel’s sifakas exhibit a seasonal reproductive cycle, with mating between January and March, during the rainy season when food is more abundant. The species is polygynandrous, meaning males and females may mate with multiple partners during the breeding season. Females are dominant within their social groups and control mating, often selecting the most dominant or successful males. Males compete for access to females through displays of aggression and dominance.
After a gestation period of about 162 to 170 days, females give birth to a single infant, usually between June and July. The newborn clings to the mother’s belly for the first few months of the mother’s transition to riding on her back. Mothers are the primary caregivers, though other group members may assist in carrying and protecting the infant. Infants are weaned by six months but stay with the group for up to two years before becoming fully independent.

Social Structure Description:
Coquerel’s sifakas live in small, cohesive family groups typically consisting of two to eight individuals, with females occupying dominant roles. Females are usually the group’s leaders, deciding where the group travels and what resources to use. Male sifakas often compete for mating opportunities but do not hold permanent dominant positions in the group. These primates are generally peaceful within their groups, with minimal aggression, except during the breeding season when competition for mates increases.
Communication within the group is facilitated through various vocalizations, body language, and grooming behaviors. Their vocal repertoire includes alarm calls, which warn the group of potential predators, and softer calls used for maintaining group cohesion. Group members share strong bonds, and mothers protect their young, who stay with them for up to two years. Coquerel’s sifakas are territorial and will defend their home ranges from neighboring groups, though interactions between groups are often limited.
Groups:
Population Trend:
Coquerel’s sifaka populations are declining due to habitat destruction, fragmentation, and hunting in some areas. The species is listed as Endangered by the IUCN, with wild populations estimated to be fewer than 10,000 individuals. While the population is stable in protected areas like Ankarafantsika National Park, it continues to decline in unprotected regions where deforestation for agriculture and illegal logging are prevalent. These sifakas are particularly vulnerable to habitat fragmentation, which isolates populations and reduces genetic diversity.
Conservation breeding programs have been established in zoos, particularly in the United States, where they help raise awareness and study the species’ reproductive biology. Captive breeding efforts have successfully maintained a small but stable captive population. However, captive individuals cannot easily be reintroduced into the wild due to ongoing threats in their native habitats. Long-term species conservation depends heavily on preserving and restoring Madagascar’s dry forests.
Population Threats:
The primary threat to Coquerel’s sifaka is habitat destruction caused by slash-and-burn agriculture, logging, and cattle grazing, which have resulted in the widespread loss of the dry deciduous forests they rely on. As human populations in Madagascar grow, more land is cleared for farming and settlements, further fragmenting sifaka habitats. This fragmentation isolates populations, limiting their ability to reproduce and maintain genetic diversity. Coquerel’s sifakas are also hunted for bushmeat in some regions, although hunting pressure is less intense compared to other lemur species.
Illegal logging, particularly of valuable hardwood trees, has exacerbated the degradation of their habitat. Additionally, climate change poses a long-term threat by altering the rainfall patterns that support the seasonal availability of food resources. While hunting is not a significant threat in all areas, habitat loss and human encroachment put tremendous pressure on the species. Without significant conservation efforts, these threats could lead to a further decline in their population.
Conservation Efforts:
Several conservation efforts are underway to protect Coquerel’s sifaka, focusing primarily on habitat preservation and restoration. Ankarafantsika National Park, a key refuge for the species, is under strict protection, and conservation organizations are working to expand protected areas and corridors to connect fragmented habitats. Reforestation projects aim to restore degraded forests and create corridors that allow sifaka populations to move between isolated forest fragments. These efforts are essential for maintaining the species’ genetic diversity and ensuring long-term survival.
In addition to habitat conservation, awareness campaigns educate local communities about preserving biodiversity and protecting lemurs. Eco-tourism initiatives have also been established, providing economic incentives for communities to engage in conservation rather than destructive activities like logging. In zoos, captive breeding programs for Coquerel’s sifaka have been successful, helping to maintain a small but genetically healthy population in captivity. Ongoing research on the species’ behavior, ecology, and reproductive biology is crucial for informing future conservation strategies.
