Abstract
Inventories of bird diversity, and vegetation compositions and structures were conducted, respectively, in Liouguei Experimental Forest monthly from March to October in 2009.  Bird bandings were also carried out at the end of breeding season in later July to get hetero-specific population parameters of bird communities.  Meanwhile, an auto-sensing recording system was built on the basis of existing wireless networks of Shanping Workstation for the development of applied bioacoustic researches.  With the severe impact of Typhoon Morakot to Taiwan in August, variations in bird assemblages between two periods were compared.  After the typhoon, point count census recorded 24 families of birds, including 15 conserved species among a total of 59 species in Fengkangshan study area.  Large scale disturbances did not significantly lower the mean numbers of either species or individuals.  As to banding works, there were 11 species of 6 families captured, amounting to 83 birds of which Grey-cheeked Fulvetta (Alcippe morrisonia) dominated.  Measurements of vegetation characters within 25 sampling points were finished, and a brief checklist with an identification key were established for further utilization.  The unusual phenology after disturbances was monitored persistently.  Furthermore, pre-tests of the auto-sensing recording system were done and an initial sound database was set ready for advanced integrations and exploitations.
