Abstract: To cope with extinction crisis, museums have a crucial role to play in preserving the life of every possible individual. Museum collections provide essential verifiable evidence of species occurrence over time and space and thus permit rigorous taxonomic, biological and ecological investigations. Two of the basic tasks required for census are gathering data on presence and abundance. By placing stickers on the wing of insect with identification information, migration patterns of insect including how far and where they fly is studied. Using mapping and visualization tools, endangered species and their vital habitats are protected. A new computer technology i.e. remote monitoring of wildlife sounds is used to listen multiple bird sounds. Thus, sound changes due to habitat loss or climate change is significant in the present study.
