Abstract : This article deals with the pattern of changes in the roosting population of P. giganteus a fruit bat. It was found that the population under study is declining by 10.2% and the rate of gain is only 0 .9%. The prospect of recovery of this colony is very weak as average increase is only 0.9% per year, therefore the conservation of this species needs immediate intervention.
