Gambian Epauletted Fruit Bat - Behavior

Behavior

The Gambian Epauletted Fruit bats are frugivorous and will appear wherever fig, mango, guava or banana trees are in fruit. The social behavior within fruit-bat camps does not stop at individual family groups. The whole colony is organized, with separate peripheral groups of immatures and non-breeding adults. The epauletted fruit bats travel in small groups of six to twenty bats. When the fruit bats are in flight, they remain together in long processions. The leaders often change, yet they retain the same direction of flight(Mickleburgh).

They frequently sniff at each other’s scent glands to establish personal recognition. Which represents high levels of social organization. When one is shot down, they show great concern and gather round swooping low to inspect it; a sign of affinity rather than totally independent behaviour. They roost during the day in mango trees and bamboo reeds or other trees. The Gambian Epauletted Fruit bats hang upside down alone or in groups up to twenty. The species' droppings support whole ecosystems of unique organisms, including bacteria useful in detoxifying wastes, and producing gasohol. This species feeds on nectar and fruits of many West African trees, presumably acting as pollinator and/or seed disperser. Some flowering trees depend on the bats for pollination(Fenton).

The pack move during sunset in large flocks from resting areas to feeding areas. To avoid predators, the bats will carry fruit away from the tree before eating. Over several nights bats may carry more than a ton of seeds from a single wild fig tree, dramatically increasing the number of seedlings that will survive in new locations. The fruit bats spend over half their lives roosting in various places(Wilson).

On the outskirts of the camp non-territorial males act as guards. They are alert to the slightest disturbance. They perform a visual inspection and either give a loud alarm signal, or remain still, keeping an eye open (Nowalk).

The Gambian Epauletted Fruit bats are unlike other bats because they use sight rather than echolocation to find food. They also rely heavily on their smell because they use it to locate food and establish bonds with one another(Nowalk).
