Why are gibbons hard to spot compared with other Cardamom animals?

Question

Accepted Answer

Gibbons are difficult to detect due to their arboreal lifestyle and rapid movement.

Gibbons are challenging to observe and document in the Cardamom Mountains primarily because they inhabit the forest canopy and move with exceptional speed. This makes them far less likely to be captured by traditional camera traps compared to other species. Conservation efforts are therefore increasingly relying on advanced technologies such as bioacoustic monitoring and artificial intelligence to accurately identify and track these elusive primates.
Gibbons' arboreal nature limits visibility

The natural habitat of gibbons is the upper levels of the rainforest, where they navigate the treetops with agility. This elevated and dynamic movement pattern means they are rarely on the ground where static camera traps are most effective for capturing images of animals like pangolins, macaques, or elephants. Their presence is often indicated by their vocalizations rather than visual sightings.
Camera traps are less effective for gibbons

While camera traps have proven valuable in documenting over 100 species within the Cardamom Mountains, including vulnerable and endangered animals, their utility for gibbon monitoring is significantly reduced. The rapid, high-canopy movements of gibbons mean they are often missed by these devices, unlike ground-dwelling or slower-moving arboreal creatures that are more consistently recorded. This limitation necessitates alternative detection methods.
Bioacoustic monitors and AI offer a solution for gibbon detection

To overcome the difficulties in visually tracking gibbons, conservationists are employing bioacoustic monitors to record their distinctive calls. These sounds are then analysed using artificial intelligence, specifically machine-learning programmes trained to distinguish gibbon vocalizations from other forest noises. This technological approach allows for the identification of gibbon presence even when the animals themselves cannot be seen.
