In order to ascertain the impact of various factors on the avian community structure in India, elaborative analysis of relevant literature was carried out to extract the impact of real factors that affect the avian community structure. The prominent factors that have direct bearing on the birds include Urbanization, extensive use of insecticides and pesticides, Physio-chemical parameters, vegetation, type of habitat, climate change, Environmental contamination, Nesting pattern and weather. Avian abundance is also affected by other factors such as migration, natality and mortality or due to changes in habitat structure and distribution pattern of food resources. Research data has pointed out strong patterns of association between bird community structure and the physical configuration of the environment. For effective avian conservation management, multipronged approach needs to be undertaken to mitigate the adversity of these factors.
