Abstract:Feeding behavior on Morus macroura fruits by Rousettus leschenaulti and Cynopterus sphinx, their feeding roosts distribution around parent trees and seed dispersal patterns were studied in a protected forest at Xishuangbanna Tropical Botanical Garden from March 2005 to May 2006. Observations on the foraging behavior of the two frugivorous bats at M. macroura fruiting trees using moonlight after dark (about 19:00) around parent tree indicated that they seldom fed on the fruit at parent tree, but left with the fruits and flew to feeding roosts in other trees to consume them. Their foraging activity peaked two times at the first half night which were around 22:30 and 23:30 and the number of foraging bouts were 13.5±2.5 and 15.0±2.3 respectively. Lowest foraging rate happened between 19:00 to 19:30 and between 20:20 to 21:00 which were 0.2±0.2 and 0.7±0.5, respectively. Most of the fruits were eaten within 10 days when fruit ripening. Bats did not selected feeding roosts randomly, but according to the species and distribution of trees favored by bats around parent trees. So the distribution patterns of feeding roost were heterogenous around parent trees. Ficus curtipes, Mesua ferrea and Alstonia scholaris were favored feeding sites for bats. Although the bats could carry seeds to a variety of feeding sites available in the environment, they clearly exhibited a preference for specific trees based on their architecture. We suggested that a preferred feeding roost is often located under a horizontal bough with a dense drooping umbrella-like crown of leaves offering cover, such as M. ferrea and A. scholaris . Besides transporting seeds to feeding sites, bats can also disperse seeds through fecal deposition. The overall seed shadow is likely to be relatively extended and homogeneous.
