Cynopterus horsfieldii
(Horsfield's Fruit Bat) is
one of the largest of the genus Cynopterus. It occurs in a wide range
of elevations, from lowland to montane, and in a broad range of habitats,
including various forest types, plantations, orchards and mangrove.
It utilizes a variety of roosts including caves, abandoned buildings and
sheltered spaces beneath large leaves. Its diet is varied and is known to
include the fruits of Elaeocarpus, Payena and Ficus (i.e.
figs). Some studies have concluded that this species is a nomadic bat,
groups of which take advantage of fruiting episodes amongst
rainforest trees far from their regular roost.
In the field it can be distinguished from the Lesser Dog-faced Fruit
Bat by its larger size, broader wings and its robust, dog-like muzzle.
Its fur is mainly greyish-brown, but males possess orange-brown fur around
the throat, which extends to the upper chest and shoulders. As with other
Cynopterus bats, its wing bones and ears are edged with white.
This species is known from southern Vietnam, Laos, Cambodia, Thailand,
Peninsular Malaysia, Borneo, Sumatra and Java. There are no adequately
documented records from Singapore, and its status there is considered
'indeterminate'.
