Bengaluru, April 9: A rare Eastern marsh harrier sighting at Hesaraghatta Lake has underscored the ecological importance of one of Bengaluru’s last remaining wetland and grassland ecosystems. The bird, typically found in northeast India and coastal marshlands, was spotted by local birdwatchers SNS Murthy and J Harish Kumar during recent visits to the lake.
Ornithologists confirm that the Eastern marsh harrier (Circus spilonotus) is an uncommon visitor to inland Karnataka, making this observation particularly significant. Experts suggest the sighting reflects the resilience of Hesaraghatta’s grasslands and wetlands, which continue to support both migratory and resident species despite urban pressures.
Hesaraghatta Lake, originally built in the late 19th century as a freshwater reservoir, has faced environmental challenges including fluctuating water levels and land-use changes. However, its designation as a conservation reserve has helped protect habitats critical for birdlife, amphibians, and other wildlife.
Beyond biodiversity, wetlands like Hesaraghatta are vital for groundwater recharge, flood mitigation, and maintaining ecological balance in rapidly urbanizing Bengaluru. Conservationists emphasize that sightings of rare species such as the harrier highlight the need for sustained protection, habitat restoration, and careful urban planning.
Birdwatchers and environmentalists hope the sighting will draw greater public attention to Hesaraghatta’s ecological value, encouraging community participation in wetland preservation and biodiversity conservation efforts.
With ongoing threats from encroachment and pollution, Hesaraghatta Lake remains a critical example of how urban wetlands can continue to support wildlife if proper conservation measures are enforced.
