If you're interested in birdwatching, Keoladeo National Park and Sarovar Bird Sanctuary are a must visit. Keoladeo National Park is famous for being home to thousands of birds (over 230 species), especially during summer.
In winter, thousands of waterfowl birds migrate here for breeding and a short-term stay. The Keoladeo National Park consists of wetlands, dry grass-woods, woodlands, and woodland swamps, and also includes many species of fish, amphibians, snakes, turtles, lizards, and other animals.
Soor Sarovar is a real bird sanctuary. Inside you can find Keetham Lake—a peaceful spot, ideal for nature lovers and birdwatchers. The sanctuary is home to more than 165 species of migratory and resident birds. Some species that you can spot here include spoonbills, egrets, greylag geese, purple herons, comb ducks, and pintails to name a few. Sarovar Bird Sanctuary is also known for its Bear Rescue Centre for rescued dancing bears.
The arrival and departure of migratory birds varies based on the water levels in the lake, the extent of winter, food sources in their other habitats, and many others factors.
The best time for birdwatching is from October to March, after the monsoon and before summer.
