Population Status Population estimates Approximately 20, mature individuals Tatayah et al. Threats to Survival Deforestation Especially felling of mature fruit trees and important roost trees Trees serve not only as food and roosting sites, but also provide buffer from cyclone winds Strong storms that destroy trees and strip fruit from trees Until recently many fruit bat species hunted for food, but now rarely on Rodrigues Island Trewhella et al.

Their wings have two thin layers that stretch over 4 thin, lightweight finger bones. They use the hooked claws on their thumbs for climbing. Like most fruit bats, Rodrigues bats do not use echolocation. Instead, they use their excellent eyesight and sense of smell to find their food.
They're active at dawn and dusk, when they land on fruit trees to feed on mangos, figs, breadfruit and tamarind pods. They crush the food in their mouths, swallow the juice, and spit out the seeds and pulp as a pellet. This helps the rainforest to regenerate. After feeding, they rest and digest their food for several hours, then return to roost in large rainforest trees. Rodrigues bats live in groups.
Single males live in separated from the harem groups. They're very vocal: "You'll often see a young Rodrigues screaming into another bat's face, and the other one typically just takes it," says keeper Laura Weiner. Their fur is woolly—golden colored on the head, neck, shoulders, and sometimes back. Their wings are black and not furred. Their wings are actually thin skin stretched between the fingers and thumb of each hand.
Their long fingers act as wing supports. The bigger, the better. The bats require tall, mature trees in large, contiguous tracts of forest for roosting and breeding. These forests also provide protection from frequent storms such as cyclones, which can easily blow down smaller stands of trees and sweep bats out to sea. Fruit, glorious fruit. Mangoes, rose-apples, figs, and tamarinds are just some of the fruits Rodrigues fruit bats seek out.
Like many other fruit bats, they squeeze the juices and soft pulp out of the fruit, rarely consuming the harder fleshy parts. Pollen is also a possible nutrition source. At the San Diego Zoo Safari Park, the Rodrigues fruit bats are fed nectar and a variety of juicy fruits, including oranges, pears, grapes, and watermelon; as well as bananas and a bat pellet to supplement their nutritional needs. Coming home to roost. Rodrigues fruit bats are sociable, and they hang out together upside down in rainforest trees.
They roost in large groups during the day. Before its numbers were threatened by habitat destruction, storms, and hunting, some of those groups could number or more members. Sunrise, sunset. Rodrigues fruit bats are most active at dawn, at dusk, and at night.
