While Chennai's famous wetlands like Pallikaranai and the historic Vedanthangal Bird Sanctuary typically dominate attention during migratory season, several under-the-radar locations are quietly establishing themselves as crucial habitats for visiting avian species.
Hidden Havens for Feathered Friends
Three particular sites are currently experiencing significant avian activity: Otteri Lake within Arignar Anna Zoological Park at Vandalur, the tall tree clusters on Sri Ramachandra Medical College (SRMC) campus at Porur, and the expansive tank at Melmaruvathur. Although the SRMC campus remains inaccessible to the general public, both Otteri Lake and Melmaruvathur welcome visitors interested in observing these seasonal residents.
Otteri Lake's Early Arrivals
Zoo authorities report that at least six different bird species have already arrived at Otteri Lake to survey potential nesting locations. The early visitors include egrets, grey herons, and open-billed storks. According to park officials, painted storks, cormorants, and spoonbills are anticipated to join them next month, potentially increasing the seasonal population to approximately 3,500 birds.
The lake has proven particularly successful for breeding populations of Asian open-billed storks, spoonbills, white ibis, grey herons, pond herons, large egrets, and darters. Interestingly, while spot-billed pelicans frequently visit Vandalur's lake, they do not use it as a breeding ground.
Painted storks typically arrive later in January and often remain until April, with their stay duration closely linked to water levels in the lake. Following recent monsoon revival efforts, the water body attracted more than 5,000 birds during the post-monsoon period.
Melmaruvathur's Decade-Long Tradition
The Melmaruvathur tank has served as a migratory destination for over ten years, with bird numbers consistently growing from initially modest figures. Local monitor P Mohanraj played a key role in alerting the Melmaruvathur Trust about the site's potential.
Inspired by successful models from other state sanctuaries and thanks to trustee G B Anbazhagan, the management installed small iron platforms in 2013 specifically designed for roosting and nesting purposes.
Urban Biodiversity Success Stories
These emerging bird habitats demonstrate Chennai's remarkable urban biodiversity resilience despite challenges like rapid urbanization and water scarcity. The zoo's proactive measures, including desilting Otteri Lake, have effectively restored natural habitats.
Meanwhile, community-driven initiatives at Melmaruvathur highlight how targeted interventions can transform ordinary tanks into flourishing bird nurseries. As the peak winter birdwatching season continues from November through March, these locations offer enthusiasts intimate opportunities to observe diverse avian flocks in settings less crowded than traditional sanctuaries.
