Species Assemblage of Birds’ Community in Protected Areas of Delhi-NCR

Abstract Green spaces in cities especially in the capital city of India provide necessary recreational, social and psychological benefits to stressing residents of the city. Cities and towns depict the extreme human-modified environments with only remnants of the original habitats present. Study undertaken to know the abundance, diversity and species richness of avian fauna in urban protected landscapes of Delhi, NCR. In the following paper, the methods include data is extracted from e-Bird of past 40 years to illustrate the changing trend of bird species from 1980-2019 from 7 greenspaces of Delhi-NCR which are Aravalli Biodiversity Park, Asola Bhatti Wildlife Sanctuary, Deer Park, Dheerpur Wetland, National Zoological Park, Northern Ridge, Okhla Bird Sanctuary, Sanjay Van, Yamuna Biodiversity Park and analysed as box plots using PAST. The result showed a varied trend from 1980-2019, which included the usage of e-Bird by the period. The result indicated that the recent decade is well updated with data on e-Bird, hence several birds’ individual is maximumly observed from 2011-2019. The study has shown the wavy trend from 1980-2019 in species composition in the capital city of India. This also suggest that people have started recording observation on a single platform and shown interest in last decade. This study will lead to taking the necessary step to maintain the avian biodiversity in the green spaces of the capital city- Delhi-NCR.
