About Pteropus rufus E.Geoffroy, 1803
Pteropus rufus E.Geoffroy, 1803, commonly called the Madagascan flying fox, is the largest bat found in Madagascar. Individuals have a body length of 23.5–27 cm (9.3–10.6 in), a wingspan of 100–125 cm (39.5–49 in), and a body weight of 500–750 g (1.10–1.65 lb). The species is primarily brown, with golden to slightly dark brown coloring across the chest and shoulder areas. Its wings range from grey to black. Males and females have similar overall appearance, though males are noted to have slightly larger heads than females. The Madagascan flying fox is one of the most common bat species on Madagascar, occurring across most of the island. It is absent from the central highlands, and its range extends from sea level up to 1,200 meters in elevation. During the day, the Madagascan flying fox roosts in large trees in colonies that can reach up to 1,000 individuals, though 400 individuals is a more typical colony size. These bats are noisy and easily disturbed; if roused, the entire colony may relocate to a new roost site. Most roosts are located on isolated trees in degraded areas. The species' diet mainly consists of fruit juice, which it squeezes from fruit inside its mouth. During this process, many fruit seeds are swallowed and dispersed to new areas as they pass through the bat's digestive tract. It also eats other tree products, including leaves, flowers, and nectar. It has been observed visiting the flowers of the kapok tree Ceiba pentandra, and is believed to pollinate this tree.
