New Delhi: The summer leg of the Delhi Bird Atlas concluded on Sunday with over 160 bird species recorded across the city, including 21 species not spotted during the winter survey, according to officials from Delhi’s forest and wildlife department. The survey spanned seven clusters and 145 one-sqkm subcells, reflecting Delhi’s diverse avian life even in urbanized environments.
The initiative, which began on April 27, saw the participation of more than 200 volunteers and 50 birding teams, who explored habitats ranging from wetlands and scrublands to residential areas and commercial zones. Over 600 checklists were submitted during the survey, offering a comprehensive snapshot of the capital’s summer birdlife.
“This brings the combined tally from both the winter and summer surveys to 221 unique bird species, which is a healthy number for Delhi, especially given the urban nature of many grids,” said Pankaj Gupta, regional coordinator for Bird Count India. He emphasized that the data will support policymakers in making informed decisions that consider the ecological value of urban habitats.
Among the 21 new species recorded during the summer were the Bonelli’s eagle, Indian bush lark, Indian golden-oriole, and the greater flamingo. Interestingly, the team also sighted an oriental turtle dove, typically a winter visitor, during the summer—a rare and unexpected observation.
The Delhi Bird Atlas is a collaborative effort led by the Delhi forest and wildlife department, in association with Bird Count India, Delhi Bird Foundation, and other conservation organizations including WWF-India, Wildlife SOS, Asian Adventures, and Delhi International Airport Limited (DIAL).
A preliminary report covering both the winter and summer surveys will be released during Wildlife Week in October, while the comprehensive Delhi Bird Atlas book is slated for release at the end of next year, following two more seasonal surveys.
“This is not just about birdwatching; it’s about understanding how birds coexist with our expanding city,” Gupta noted. “The atlas will be a vital tool for conservation and planning in Delhi.”
