A Gaoligong hoolock gibbon feeding on the fruit of Rhaphidophora hookeri in Gaoligongshan National Nature Reserve in 2013. These gibbons are endangered and are a first-level protected species in China. Since they are canopy dwellers it is difficult to catch a close-up of feeding behaviour. Moreover, the gibbons are timid and sensitive. Fortunately, since the gibbon couldn’t resist the fruit in his hand, I had enough time to capture his cute facial expressions. Plants in the Araceae family are said to be toxic and I noticed that the gibbon often opened his mouth and stuck out his tongue. Looking at his yellow tongue, I thought that although the fruit may be delicious his tongue will go numb if he ate too much.

The Golden Langur (Trachypithecus geei) is an endangered species of primate endemic to Bhutan and adjoining areas of Assam. The Assam population is severely affected by deforestation and loss of habitat. Bhutan is the last bastion for their survival as a species.

While trekking in the Garbhanga Reserve Forest in Assam, I came across a troop of capped langurs (Trachypithecus pileatus) on the forest fringe. This individual stopped right in its track and stared deep into my camera for a few seconds, enabling me to capture the moment. The morning light enhanced the golden colour of its coat.

A troop of capped langurs led by the alpha male and consisting of several females and offspring, photographed while trekking in Pancharatna Hill on the banks of the Brahmaputra in Assam’s Goalpara District. Capped langurs are arboreal and rarely come down to the ground, so photographing them is quite challenging. They are found in Bhutan, Myanmar, India and Bangladesh. Their population is declining because of habitat loss.

The Gaoligong hoolock gibbon is one of China’s first-level protected animals and one of the most endangered wild species. They are estimated to number less than 150 and most gibbon families live in fragmented forests. The gibbon marks its territory by vocalizing (calling) in the early morning. In the spring of 2012, when I was shooting a family of gibbons, I happened to catch up with their calling time. The male was enjoying calling in front of me, with innocent eyes, a bright singing voice, and a lovely mouth shape.
I haven’t seen many photos with a Chinese national first-level protected animal, the Gaoligong hoolock gibbon, and a Chinese national first-level protected plant, Magnolia cathcartii, in the same frame. I took this picture in 2018, while tracking a gibbon family. Through a gap in the forest canopy, I could see the mother gibbon sitting on a tree eating fruit. I hurriedly took a few photos and she left. I didn’t expect that the gibbon and the magnolia were together at that moment! Because the leaves are very similar, I thought that the fruit was also of the magnolia. After consulting with an expert, I found that the gibbon was sitting on a banyan tree and feeding on a fig. But it happened that there was also a flowering magnolia, which was indeed lucky.

A Yunnan snub-nosed monkey and her child in their natural habitat.
As the final light of the day hid behind the canopy, the first bat of the night unfolded its wings, and the last bird of the day went to its roost, we started our night safari in Lawachara National Park in search of the red-eye. On that mysterious forest trail we found two shiny eyes in a tree, a female Bengal slow loris (Nycticebus bengalensis). One of the least known primates due to its nocturnal behavior, this globally vulnerable species has a serious toxic bite that is often used against predators. Female lorises are known to protect infants by licking the toxin onto their fur.

The loss of canopy connectivity is the main threat to strictly arboreal high canopy animals like the hoolock gibbon. Habitat fragmentation due to highways, railway lines and other linear infrastructure is the main threat to hoolock gibbon survival in Bangladesh, greatly influencing their daily path length (DPL). To fulfill their DPL and food demands they sometimes have to make long jumps over roads or railway lines and these could be life-threatening. Here, a gibbon group that has reached the end of the canopy connection decides to make a long jump. If fragmentation continues, what is the future for these animals?
