Endangered
Phayre's leaf monkey
Trachypithecus phayrei
Phayre's leaf monkey is an Old World monkey in the family Cercopithecidae (order Primates) — Trachypithecus phayrei, recorded as Endangered.
Appearance
Phayre's langur is characterized by white coloration around the ventral, mouth, and eye area. The white fur is especially contrasting with the overall deep bluish-brown fur all over its body with darker shades at the head, below the elbows, and at the end of the tail. The infants have a straw-colored natal coat, making it easily distinguishable in a group.
The average head-body length ranges from 530–580 mm (21–23 in) in males and 495–580 mm (19.5–22.8 in) in females. The tail is usually longer than its body, with an average of 700 mm (28 in) for males and 750 mm (30 in), for females.
Range and habitat
Pharye's langur is found in tropical, deciduous, and evergreen forests of North-East India, Eastern Bangladesh, and Western Myanmar. It can also be seen residing in secondary forests such as bamboo clusters and rubber plantations. In India, the most common roosting trees range from heights of 6–15 m (20–49 ft) and have an extensive canopy, e.g., Ficus hispida and Triadica sebifera in Mizoram.

Diet and breeding
The diet varies between seasons and different regions, showing adaptation to the local flora. Plant parts with less fiber and high proteins and sugars such as young leaves are usually preferred while foraging.
In Satchari National Park in Bangladesh, they feed primarily on Ficus hispida, Albizia chinensis, and Vachellia nilotica. Phayre's langurs living in local rubber plantations in Mizoram majorly consume leaves of Hevea brasiliensis showing that diet is affected by the plant diversity in its home range.
In crisis
Populations from further east are now thought to belong to other species. It is listed as Endangered on the IUCN Red List and is threatened by hunting and loss of habitat. The IUCN Red List has deemed the population of Phayre's langur to be decreasing.
The recent reclassification of Phayre's langur has led to the underestimation of the status of the decline in the species' population. It is also listed in the CITES Appendix II, to protect its illegal poaching and trading locally.
