Habitat Abundance Morphology And General Biology Of Indian Flying Fox ( Pteropus Giganteus ) At Dir Malakand - 2009

This study was carried out from June, 2008 to December, 2008 to study the habitat, abundance, morphology and general biology of Indian flying fox (Pteropus gigc,nteus) at Dir, Malakand, Mardan and Charsadda districts of N. W. F. P - Pakistan. Five different roosts viz. (a) Dargai bridge, situated on main road from Peshawar to Swat, tehsil Dargai and district Malakand, (b) Ghaffar khan village, situated on main road from Shakoor to Mandani, tehsil Tangi in Charsadda district, (c) Chail Kandov Baba, situated on main road from Dargai to Katlang tehsil Takht Bhai in Mardan district, (d) Chakdara bridge, situated on river Swat at the junction of Chakdara and Swat road tehsil C'hakdara and Dir district, and (e) Fishing hut, situated on river Swat near Chakdara bridge tehsil Chakdara in Dir district were sampled for the study of habitat, abundance and morphology and general biology of the Indian flying fox (Pteropus giganteus).

Field data was also collected to know the habitat, abundance and general biology of these bats in the study area. The carcasses of the bats were collected from the ground underneath the above mentioned five roosts. Out of five roost only two i.e. Ghaffar Khan Village and Chail Kandov Baba where the habitat was composed of loamy soil and vegetated with maximum number of Eucalyptus glob ulus and some grasses.

Before being weighed the external body measurements of some specimens were recorded. The skulls of these specimens were also prepared for recording different parameters of the skull. The proportion CL/HBL, FL/HBL, TL/HBL and CaL/HBL were almost similar in the two types of skulls whereas the proportion ELIHBL, EB/HBL, TWC/HBL, 21I metaJHBL, 3 metaJHBL, 41h metaJHBL, metaJHBL, FAL/HBL and meta/HBL, FAL/HBL and WS/HBL was somewhat greater in the case with skull without ridge. Only the proportion BW/HBL was greater in the case of the skull having ridge than those without ridge.

Since all the specimens wer putrefied, it was not possible to autopsy them so the reproductive data of any of these specimens could not be obtained. However some general observations of the live bats were recorded.
