Cormorants and Anhingas in Rajaji National Park

Rajaji National Park, nestled in the scenic landscapes of Uttarakhand, India, is renowned for its diverse flora and fauna. Among its avian inhabitants, cormorants and anhingas stand out as remarkable species. These aquatic birds, with their unique adaptations and intriguing behaviors, add a touch of elegance and mystique to the park’s vibrant ecosystem. In this article, we delve into the lives of cormorants and anhingas in Rajaji National Park, exploring their habits, habitats, and ecological significance.

Cormorants – Masters of Underwater Pursuits

Rajaji National Park provides an ideal habitat for several species of cormorants, including the Indian cormorant (Phalacrocorax fuscicollis) and the Little Cormorant (Microcarbo niger). These sleek, black birds are often spotted along the park’s rivers, lakes, and wetlands, where they engage in their remarkable hunting behavior.

Adaptations for Underwater Hunting

Cormorants are well-adapted for underwater pursuits, boasting streamlined bodies and powerful webbed feet. Their dense plumage lacks waterproofing oils, allowing them to dive deeper and stay submerged for longer periods compared to other water birds. This unique adaptation aids in their efficient hunting of fish, their primary prey.

Feeding Behavior and Ecological Role

Cormorants are voracious predators, preying on a variety of fish species found in the park’s water bodies. Their hunting prowess plays a crucial role in regulating fish populations, thereby contributing to the ecological balance of aquatic ecosystems within Rajaji National Park.

Conservation Concerns

Despite their ecological importance, cormorants face various threats in their natural habitat, including habitat loss, pollution, and human disturbance. Conservation efforts aimed at preserving their wetland habitats and mitigating anthropogenic pressures are essential for ensuring the continued survival of these majestic birds in Rajaji National Park.

Anhingas – The Submerged Spearhunters

Another fascinating avian species found in Rajaji National Park is the anhinga (Anhinga melanogaster), also known as the snakebird or Oriental Darter. These slender, snake-like birds are distinguished by their long necks, sharp bills, and distinctive hunting techniques.

Unique Adaptations for Hunting

Anhingas possess specialized adaptations for underwater hunting, including elongated necks and spear-like bills. Unlike cormorants, their plumage lacks waterproofing oils, allowing them to achieve neutral buoyancy underwater—a feature that facilitates their stealthy pursuit of fish.

Behavioral Ecology

Anhingas are solitary hunters, often seen perched on branches near water bodies, patiently awaiting their prey. When a suitable target is spotted, they stealthily submerge themselves, using their sharp bills to skewer fish with remarkable precision. This unique hunting strategy sets them apart from other avian species and highlights their adaptability to aquatic environments.

Conservation Challenges

Similar to cormorants, anhingas face various conservation challenges in Rajaji National Park, including habitat degradation, water pollution, and human disturbance. Efforts to safeguard their natural habitats and mitigate anthropogenic threats are crucial for ensuring the long-term survival of these charismatic birds within the park.


Cormorants and anhingas are emblematic representatives of Rajaji National Park’s rich avian diversity. Their remarkable adaptations, unique hunting strategies, and ecological roles underscore the importance of conserving wetland habitats within the park. By addressing conservation challenges and promoting sustainable management practices, we can ensure the continued presence of these aerial acrobats, enriching the natural heritage of Rajaji National Park for generations to come.
