Nawabganj Bird Sanctuary, officially renamed Shahid Chandra Shekhar Azad Bird Sanctuary in 2015, is a prominent avian habitat located in the Unnao district of Uttar Pradesh, India. Situated approximately 45 kilometers from Lucknow along the Kanpur-Lucknow highway, the sanctuary encompasses a lake and its surrounding ecosystems. The sanctuary serves as a crucial refuge for both resident and migratory bird species, with over 25,000 waterbirds regularly recorded and 220 species documented. Notably, it hosts globally threatened species such as the endangered Egyptian vulture (Neophron percnopterus) and Pallas's fish eagle (Haliaeetus leucoryphus), as well as the vulnerable lesser adjutant (Leptoptilos javanicus) and woolly-necked stork (Ciconia episcopus). Nawabganj Bird Sanctuary stands as a testament to India's commitment to preserving biodiversity, offering a haven for numerous bird species and enriching the ecological tapestry of the region.
