Identification:
Forearm length: 62-70 mm. This species has a small snout and a long, moist tongue adapted for consuming nectar and pollen. A distinguishing feature compared to similar Rousettus species is the absence of a claw on the second digit. A distinct tail is present. Weight: 45-60g.
Biology and Ecology:
Their primary diet consists of nectar and pollen, and they are a major pollinator of forest trees, including commercially important species such as durian (Durio zibethinus), red silk cotton tree (Gossampinus malabarica), and mangrove (Rhizophora sp.). They typically roost in colonies of thousands within caves. They can travel up to a 30 km radius from their roosting sites in search of food. In Peninsular Malaysia, this species breeds throughout the year.
Distribution:
Found throughout Southeast Asia, including Sulawesi and the Philippines, Thailand, and Vietnam.
In Vietnam, this species is present in Lai Chau (Pa Ham), Quang Binh (Ba Don), Quang Tri, and Lam Dong (Fyan).
Value:
This is a rare species, valuable for scientific research, aesthetic appreciation, and as a pollinator of flowering plants in nature.
