An exploratory study to examine how land-use change due to urbanization has an effect on the distribution pattern of birds species. Land-use change and Land-use intensification due to urbanization and increasing human population has seen transformations accompanying the urban sprawl in the recent time leading to rapid changes in communities of plants and animals affecting the natural landscape.Delhi is recorded as one of the largest urban conglomerations of India, next to Nairobi and Kenya supporting the largest diversity of birds and very little is known on the effects of these conversions on species, populations, communities and ecosystems. Quantifying changes in the landscape to understand how present and future land-use will impact species hence becomes very important. Birds have been used as an indicator to study these changes since they react rapidly to these environmental changes. Hence it becomes important to know the avi-faunal composition supported by various micro-urban habitats to obtain a complete overview of the avian status across metropolitan area like Delhi. We assessed the changes in the avi-faunal composition of the six-land use types across Delhi region namely the dense vegetation ( urban forest patch ) , the sparse vegetation ( gardens) , agricultural land use type , water-body , residential and industrial areas. This was done by examining the diversity, density, abundance, community ecology and mapping of birds in a series of habitat graded from relatively pristine to highly urban and by comparing these estimates to human induced land use changes. The findings of the study could be used to inform important decisions by quantifying data on how the present and past land-use changes will have an affect on bird diversity which can assist the land-use planners to maintain pre-development levels of biodiversity ; on how and where cities grow and can also help to conceptualize a long term conservation programme in management and monitoring of different areas across Delhi.
