My Celebration with my TN friend after my second year in this exciting forum.

The Dusky Leaf Monkey, Spectacled Langur, or Spectacled Leaf Monkey (Trachypithecus obscurus) is a species of primate in the Cercopithecidae family. It is found in Bangladesh, India, Laos, Malaysia, Myanmar, and Thailand

I think this is the first image of Spectacled Langur or dusky leaf monkey. i kept this shot to celebrat my 2 years on TN. This is something quite special to me.
All these years, I have been hearing its howling on the hills. But I never see it personally. I have been hearing its name, the Malay called it " Lotong".
This day I passed by the hill known as Bukit Kubu Recreation Forest Reserve, whichj is a reserved limestone hill. During that time, it was a dry spell.
A troop of these monkey were having lunch, eating leaves and cattails flowers and stalks. But they were very sensitive and full awareness. They would ran away upon seeing human approaching. But in cars they do tolerate. I just cant open the car door, they would ran away. After 2 tries, I have to slowly open the side windscreen and shot them.
I have told you that this was my first time, I did not really know their features very well except that they do wear spectacle. another this I did noticed is that they looked blurry and the camera found it hard to really focus. finally it did but one thing I realised is that the tail is quite long. I realised it until I look in the computer. So I like to celebrate this with all my TN friends.

Some exciting facts about this monkey.

From : http://www.treknature.com/upload.php
The dusky leaf-monkey is a folivorous species, but it will also consume fruit and flowers. Young leaves constitute a high proportion (52%) of the diet for this species (Aldrich-Blake, 1978). Fruit consumed tends to be unripe (MacKinnon and MacKinnon, 1980). Dusky leaf-monkeys are able to take advantage of unripe fruit, which have chemical defenses, by the same means that they breakdown toxins in plant leaves, the bacteria found in their digestive system (MacKinnon and MacKinnon, 1980). Among fruit consumed includes figs (Ficus) of the following species: Ficus sumatrana, Ficus delosyce, Ficus stricta, Ficus cucurbitina, Ficus dubia, and Ficus aurantiacea (Lambert, 1990). The dusky leaf-monkey will consume both ripe and unripe figs (Lambert, 1990). During the dry season this species will consume Intsia palembanica, Koompassia excelsa, and Koompassia malaccensis (Curtin, 1980). Dusky leaf-monkeys will feed in the emergent trees, which is higher than other sympatric langurs (Curtin, 1976, 1980; Curtin and Chivers, 1978; Fleagle, 1976, 1978b). During the day, the main group splits up and forms smaller foraging groups (Fleagle, 1988). The dusky leaf-monkey prefers to forage in the main canopy and the emergent layer of the forest (Fleagle, 1988, 1978). When feeding this species will sit on large branches and boughs (Fleagle, 1978a). This species will spread foraging activity throughout the day so as not to overload their digestive processes that remove plant toxins and process leaf matter efficiently (MacKinnon and MacKinnon, 1980).

The dusky leaf-monkey can have a social system of two types: multimale-multifemale or unimale (Curtin and Chivers, 1978). This is a territorial species where home range boundaries rarely overlap (Curtin, 1976; MacKinnon and MacKinnon, 1980). Territories might be maintained because of the territorial honks emitted by the adult male (Curtin, 1980). Solitary individuals are known to occur of both sexes (Curtin, 1976; Curtin and Chivers, 1978). Adult males do not interact with many members of the group; their roles are confined to predator detection, maintenance of group cohesion during travel, and defense of territorial boundaries (Curtin, 1976, 1980). Males will not become aggressive with intruders; rather hide with the rest of the group (Curtin, 1980). As compared to the banded langur, the dusky leaf-monkey has a higher frequency of social interactions within the group (Curtin, 1980). Infants will be transferred between females, and sometimes one adult female will watch as many as four infants while the other females rest and feed (Curtin, 1976, 1980; Badham, 1967). Juveniles will be associated more with an adult female than with members of their own peer group, which is different from banded langurs (Curtin, 1980).

Aggression is low amongst group members (Curtin, 1976, 1980). When aggression does occur amongst group members, there is a high rate of reconciliation (Arnold and Barton, 1997, 2001a). Affiliative dyadic relationships, and not kinship and rank, are associated with conciliatory tendencies (Arnold and Barton, 1997, 2001a). Ventro-ventro hugging (embracing) is an important behavior during reconciliation (Arnold and Barton, 1997, 2001a). Former opponents will engage in hugging as will victims with a third party who with they have a strong bond (Arnold and Barton, 1997, 2001b). Social grooming was the most popular first contact behavior after an agonistic encounter (Arnold and Barton, 2001b). The intensity of aggression was not found to have an effect on the likelihood of reconciliation to occur (Arnold and Barton, 2001a). Reconciliation was found to occur within three minutes after an agonistic encounter (Arnold and Barton, 2001a). Reconciliation can be initiated by the recipient of aggression or the aggressor (Arnold and Barton, 2001a).

Groups will split-up during the day to form subgroups that forage and then reunite during the evening (Curtin, 1976, 1980). The most common subgroup is an adult female and a juvenile (Curtin, 1976, 1980). Subgroups tend to be large in the early morning and smaller in the mid and late afternoon (Curtin, 1976, 1980). Subgroups remained in contact through visual means and also by knowing familiar travel routes through the forest (Curtin, 1976, 1980). Ranging patterns of a group are conservative by nature, which helps in predicting where a subgroup will be at a certain time (Curtin, 1980). The ranging patterns might also explain why there is little home range overlap between neighboring groups (Curtin, 1980). Subgroups may be adaptive for feeding on a limited and dispersed food supply such as leaves (Curtin and Chivers, 1978). Trees may be dispersed throughout the forest, and new leaves may replace themselves at a slow rate (Curtin and Chivers, 1978).

Social play in the dusky leaf-monkey includes wrestling, sham-biting, jumping on or over, chasing, fleeing, and tail pulling (Arnold and Barton, 2001a). Play face will occur when engaging in social play (Arnold and Barton, 2001a).

The dusky leaf-monkey is sympatric with the banded langur, the pig-tailed macaque (Macaca nemestrina), the long-tailed macaque (Macaca fascicularis), the siamang (Hylobates syndactylus), and the white-handed gibbon (Hylobates lar) in a diptocarp forest near Kuala Lumpur (McClure, 1964; MacKinnon and MacKinnon, 1980). Curtin and Chivers (1978) found that this species associates with siamangs, feeding in the same or adjacent trees and using the same pathways when traveling. Associations between dusky leaf-monkeys and siamangs were found to be most frequent at dawn and dusk (Curtin and Chivers, 1978).

social grooming: This is when one individual grooms another and is used to reinforce the bonds between individuals.

embrace: (hugging) This is when two individuals will sit ventro-ventrally (chests touching) and with both arms around each other (Arnold and Barton, 2001a). Kneading of the fur will often accompany this behavior (Arnold and Barton, 2001a). This behavior serves to communicate reconciliation and to consol the recipient (Arnold and Barton, 2001a, b). The aa-aa will usually accompany this behavior (Arnold and Barton, 2001b).

hold bottom: This is when one individual will sit and hold the hindquarters of another individual that is sitting or standing (Arnold and Barton, 2001a). This behavior serves to communicate domination on the part of the sender (Arnold and Barton, 2001a).

jumpkick: This is when one individual will jump in front of another and kick the individual one or more times (Arnold and Barton, 2001a). This behavior serves to communicate aggression (Arnold and Barton, 2001a).

hit: This is when individual will strike another with force (Arnold and Barton, 2001a). This behavior serves to communicate aggression (Arnold and Barton, 2001a).

grab: This is when one individual will grasp another with one or both hands, restraining the individual (Arnold and Barton, 2001a). This behavior serves to communicate aggression (Arnold and Barton, 2001a).

grappling: This is when two individuals are in conflict with each other, grabbing, pulling, wrestling, and kicking each other continuously (Arnold and Barton, 2001a). This behavior serves to communicate aggression (Arnold and Barton, 2001a).

Hi Foozi,

Congrats on getting a first on TN. This picture is lovely. The langur is in a nice pose and the detail is very good. Good exposure between light eye rings and darker body.
Good capture and TFS


Ciao Foozi. Two years with us and exciting works MF! Best compliments for the rare capture in intirgant playing of light. TFS.


Hi Foozi,

Congratulation for your 2 years on TN, the tree is framing well the monkey. The point of view is showing the details and colors of the dusty leaf monkey. The afternoon light has a good effect on the colors. I suggest that you try an exposure speed of 1/500 of a seconds. Have a nice day.

Hello Foozi,
At first thanks for all the interesting postings you showed us in these two years. We discovered many new and exciting subjects; I also appreciate your own personal style to take pictures.
This is of course again a very intersting and well documented picture. This Spectacled Langur looks really cute and you have been very lucky to catch it with your lens, even if the approach doesn't seem easy.
Take care!
Kind regards

Hello Foozi,
A spectacular image to celebrate your two year milestone. What an attractive looking monkey with his big black eyes circled by the white eye rings. His snow white beard is also an eye catcher. His fur looks extremely soft and the texture seems very fine. Nicely composed image with great exposure and beautiful colors. Well done!!!

Haha:) What a cute langur ready to jumping MF Foozi.
This is utterly great contribution to us and TN site MF!
TFS and have a nice week!
