Corbett National Park, nestled in the foothills of the Himalayas, is not just a haven for big cats and diverse wildlife; it's also a paradise for birdwatchers. The park's varied landscapes, ranging from dense forests to open grasslands and riverine habitats, provide a conducive environment for a rich avian diversity. Here's why Corbett is a must-visit destination for bird enthusiasts:

1. Diverse Habitats: Corbett encompasses a range of habitats, including dense Sal forests, riverbanks, grasslands and high-altitude plateaus. This diversity attracts a wide array of bird species adapted to different ecological niches. 

2. Rich Riverine Ecosystem: The Ramganga River, which flows through the park, creates an ideal environment for both resident and migratory birds. Kingfishers, fish eagles and a variety of waterfowl are commonly sighted along the riverbanks. 

3. Grasslands and Open Spaces: The grassy meadows and open spaces in the park provide an excellent setting for species like the Indian Roller, Crested Serpent Eagle and various pipits and larks. Raptors can often be spotted soaring over these open landscapes.  

4. Specialized Birding Zones: Certain zones within Corbett, such as the Dhikala Grasslands and the Bijrani Zone, are particularly rewarding for birdwatchers. These areas have been known to host an impressive diversity of species, including many that are not easily found elsewhere. 

5. Resident and Migratory Species: Corbett is home to a mix of resident birds that can be spotted year-round and migratory species that visit during the winter months. Migratory birds include waterfowl like ducks and geese, as well as birds of prey like Ospreys. 

6. Rare and Endangered Species: The park is also home to some rare and endangered species, such as the Great Hornbill and the Pallas's Fish Eagle. Spotting these majestic birds adds a special thrill to any birdwatching expedition. 

7. Expert Naturalists and Guides: Corbett offers the services of experienced naturalists and guides who are well-versed in the park's avian residents. Their knowledge enhances the birdwatching experience, helping enthusiasts identify and understand the behaviors of different species. 

8. Best Times for Birdwatching: While birdwatching can be rewarding throughout the year, the winter months, from November to February, are considered the best. During this time, many migratory species arrive in the park, adding to the overall diversity. 

Whether you're a seasoned birder or a novice with a budding interest in birds, Corbett National Park provides an immersive and rewarding experience. The symphony of bird calls echoing through the diverse landscapes makes every visit a memorable birdwatching adventure.
