About Kasavanahali Lake (Sarjapur Road)
Kasavanahali Lake, also known as Kasavanahalli Kere, is an urban wetland situated along the rapidly developing Sarjapur Road corridor of Bengaluru. Despite being surrounded by residential neighbourhoods and ongoing urbanisation, the lake provides an important open-water and wetland habitat for a diverse range of birds. The combination of open water, shallow margins, wetland vegetation and surrounding open spaces creates suitable conditions for waterbirds, waders, raptors and terrestrial species. The lake is particularly valuable for observing birds associated with freshwater habitats, including ducks, coots, moorhens, swamphens, herons, egrets, cormorants and ibises. Its relatively accessible setting also makes it a useful site for urban birdwatching, nature education and increasing awareness about the importance of Bengaluru’s remaining wetlands.
The surrounding landscape adds further habitat diversity, allowing visitors to observe birds beyond the waterbody itself. Open areas around the lake provide feeding grounds for lapwings and other ground-foraging species, while trees and vegetation offer shelter and food for resident urban birds. Raptors such as Black Kite and Brahminy Kite can be seen using the area, while species such as Asian Openbill, Oriental Darter and several species of herons and egrets highlight the ecological value of the wetland. With increasing development along Sarjapur Road, protecting the lake’s water quality, vegetation and natural edges is important for maintaining its biodiversity. Kasavanahali Lake demonstrates how urban wetlands can continue to support significant bird diversity when their habitats are protected and managed responsibly.

Summary of Walk
Ataavi’s 5 September 2026 walk at Kasavanahalli Lake on Sarjapur Road, Bengaluru, saw a strong turnout of participants led by guide Rahuldev Rajguru around the lake’s wetland habitat. The morning offered a lively mix of raptors and waterbirds, with the group recording an excellent 40 species — one of the richest counts of the entire week. The lake’s blend of open water, reeds, and surrounding greenery made it a fantastic setting for birders of all levels, and a great example of how urban wetlands in Bengaluru’s fast-growing tech corridor can still thrive. The lake continues to be one of the most reliable birding spots along Sarjapur Road, drawing repeat visitors eager to see what the changing season brings.
A true highlight of the walk was a Black Kite spotted with a large fish catch, giving the group an extended, close-up view of the raptor in action as it settled to feed nearby. Asian Openbill Storks also made a memorable close appearance, feeding within easy viewing distance of the trail. Rahuldev’s deep familiarity with the lake’s seasonal patterns helped the group make the most of every sighting, and participants left with a strong sense of just how much birdlife Kasavanahalli Lake continues to support right in the heart of the city. Several participants noted this was their first time observing a raptor hunting so closely, calling it one of the highlights of their birdwatching journey so far.
