RT Journal A1 Cole TB T1 GIant indian fruit bat JF JAMA JO JAMA YR 2009 FD October 28 VO 302 IS 16 SP 1736 OP 1736 DO 10.1001/jama.2009.1503 UL http://dx.doi.org/10.1001/jama.2009.1503 AB Bats are the only mammals capable of sustained flight. Rather than flexing their forelimbs to fly, as birds do, they flap their webbed digits, scooping handfuls of air. Most bats eat insects, but about a third of bats species are frugivores, such as Pteropus giganteus, also known as the giant fruit bat or flying fox. Giant fruit bats weigh 600 to 1600 g and have a wingspan of 1.2 to 1.5 m. They live in tropical forests and swamps throughout Bangladesh, Myanmar, India, Pakistan, and Sri Lanka. During the day they roost by the hundreds in large trees, hanging upside down by their feet and wrapped in their membranous wings. When they are not dozing, they fan themselves to aid in thermoregulation, move around in the tree, and vocalize to communicate with one another. A video recording of the roosting behavior of fruit bats can be found at http://www.indiavideo.org/kerala/land-and-people/flora-and-fauna/wildlife/animals/the-indian-flying-fox-586.php.
