Overview: The Riverine Sanctuary of the National Capital Region
Located directly at the point where the Yamuna River leaves New Delhi and enters the state of Uttar Pradesh in Gautam Buddha Nagar (Noida) district, Okhla Bird Sanctuary encompasses 4.00 square kilometers of open river water, shallow mudflats, and extensive reedbeds.
Established in 1990 under the provisions of the Wildlife (Protection) Act of 1972, the sanctuary was formed around the historical impoundment created by the **Okhla Barrage** (constructed in 1874 to divert Yamuna waters into the Agra Canal). Classified globally as an **Important Bird Area (IBA IN-UP-20)** by BirdLife International, Okhla serves as an indispensable refueling haven along the **Central Asian Flyway**.
Despite being surrounded by the dense urban metropolis of Delhi, Noida, and Faridabad, the sanctuary provides refuge to over **300 recorded bird species**, including globally threatened taxa such as the **White-rumped Vulture**, **Indian Vulture**, **Baer's Pochard**, **Sarus Crane** (Antigone antigone), **Black-bellied Tern**, and **Bristled Grassbird**.
Yamuna River Limnology & Reedbed Stratification
The sanctuary's micro-habitats are structured by the regulated water levels of the Okhla Barrage:

Avian Spectrum & Central Asian Migrants
Okhla is celebrated as one of the premier birding hotspots in Northern India:
Northern Shoveler
Spatula clypeata • Filter-feeding Duck
Arrives in thousands from Northern Eurasia, using its large spatulate bill to strain zooplankton from shallow surface waters.
Black-bellied Tern
Sterna acuticauda • Endangered River Tern
Gracefully patrols the Yamuna river channel, plunge-diving to catch small fish along open water stretches.
Sarus Crane
Antigone antigone • UP State Bird
Resident breeding pairs forage in the peripheral marshy fields, their resonant trumpeting calls heard across the wetland.
Bristled Grassbird
Schoenicola striatus • Vulnerable Specialist
Shy, elusive songbird inhabiting the dense Typha reedbeds, performing song flights over tall grass tops at dawn.
Bar-headed Goose

Bluethroat

Other prominent species include the **Pallas's Gull**, **Brown-headed Gull**, **Osprey**, **Western Marsh Harrier**, **Greater Spotted Eagle**, **Glossy Ibis**, **Purple Heron**, and **Eurasian Spoonbill**.
Urban Ecology & Eco-Sensitive Zone Conservation
Okhla represents a vital ecological buffer zone amidst one of the fastest-growing urban areas in the world. In 2015, the Ministry of Environment, Forest and Climate Change (MoEFCC) notified an official **Eco-Sensitive Zone (ESZ)** around Okhla Bird Sanctuary, strictly regulating polluting commercial development and protecting the groundwater recharge capacity of the Yamuna floodplains.
The Uttar Pradesh Forest Department, in collaboration with the Delhi Bird Club and wetland ecologists, conducts weekly water hyacinth harvesting drives, desilting of internal shallow channels, and systematic water quality testing to maintain healthy dissolved oxygen levels.
Equipped with elevated wooden watchtowers, bird observation hides, information signboards, and bamboo walkways, Okhla serves as a vibrant outdoor classroom where thousands of Delhi NCR residents and school children reconnect with wild nature every week.
Annual Asian Waterbird Census (AWC) counts coordinated by Wetlands International regularly log over 30,000 individual birds at Okhla, providing valuable long-term ecological data on environmental fluctuations across the greater Yamuna River basin.
