BiologyThe Madagascan rousette feeds mainly on the juices of fruits, soft fruit pulp and nectar, and may play an important role in the forest as a pollinator and seed disperser (1) (2) (5), particularly as its small size makes it the only fruit bat in Madagascar that can fly within intact forest (1) (3). The rudimentary echolocation is likely to be used only for orientation, with food being detected using vision and scent. The Madagascan rousette may fly considerable distances each night in search of food (2). This species may form roosts of up to several hundred individuals (2), although a single cave roost of over 5,000 has also been recorded (8). During the daytime, roosts are noisy and the bats often restless, continually competing for the best positions, and fights are not uncommon (2) (5). In general, Rousettus species have extended breeding seasons which follow the rains, sometimes with two peaks each year (5). Usually, a single young is born, or occasionally twins, after a gestation period of around four months (2).
