Bird Walk at Bidre Lake (Bannerghatta Road), Bengaluru

About Bidre Lake

Bidre Lake, located off Bannerghatta Road in Bengaluru, is a small but ecologically important freshwater wetland that serves as a refuge for a wide variety of birds and other wildlife amidst the city’s rapidly expanding urban landscape. Surrounded by patches of grassland, scrub vegetation, and scattered trees, the lake supports both resident and migratory bird species throughout the year. Waterbirds such as herons, egrets, cormorants, kingfishers, and jacanas are commonly observed along its margins, while raptors, bee-eaters, sunbirds, and other terrestrial birds make use of the surrounding habitats. The diversity of microhabitats within and around the lake makes it an attractive site for birdwatchers and nature enthusiasts.
Beyond its importance for birds, Bidre Lake plays a vital ecological role by supporting aquatic biodiversity, regulating local hydrology, and providing habitat for amphibians, reptiles, butterflies, dragonflies, and numerous aquatic invertebrates. The wetland contributes to groundwater recharge and acts as a natural buffer during periods of heavy rainfall. Despite increasing urbanisation around Bannerghatta Road, the lake continues to function as a valuable green space, offering opportunities for environmental education, biodiversity monitoring, and citizen science. Continued conservation and habitat management are essential to ensure that Bidre Lake remains a thriving ecosystem for both wildlife and the local community.

Wading birds are well represented by the Black-headed Ibis, Indian Pond-Heron, Eastern Cattle Egret, Grey Heron, and Purple Heron, which frequent the shallows and reed edges. The Common Kingfisher and White-throated Kingfisher are regularly seen along the water’s edge, while the Asian Green Bee-eater and White-cheeked Barbet add colour to the surrounding trees.

Summary of Walk

Fifteen participants turned out for a full-house session with guide Rahuldev Rajguru at Bidre Lake on Bannerghatta Road, Bengaluru, despite another round of gloomy, overcast weather that threatened to dampen the mood before the walk even began. The lake’s mix of open water and fringing vegetation once again delivered a strong showing, with the group recording 48 species over the course of the walk, a solid tally that reflected the site’s growing reputation as one of the city’s more consistent birding spots regardless of the conditions overhead. Among the highlights were uncommon sightings of the Common Iora and Small Minivets, species that don’t always show up reliably on every visit, adding an extra layer of excitement for the group as the walk progressed along the water’s edge. The walk also featured an excellent display from Tri-coloured Munias and Scaly-breasted Munias, whose active flocking behaviour gave participants plenty of time to observe and photograph them at close range. Despite the weather working against them from the start, the group’s persistence paid off handsomely, resulting in a walk that balanced dependable common species with a few genuinely special finds along the Bannerghatta Road stretch of the lake, reinforcing why Bidre Lake keeps drawing repeat visitors from across the city.
