Commonly known as Bharatpur Bird Sanctuary, comes under the Keoladeo National Park and bears the same official name. Bharatpur is the pilgrimage for the bird lovers. Once, hunting grounds of former Maharajas of Bharatpur is now UNESCO World Heritage site. Although small in size, 29 sq. km, it boasts more than 375 species of birds, and more than 132 of them breed inside the Keoladeo Ghana National Park and nearly every year new ones are added to the list.

The sanctuary not only attracts birds from India but also from places like Europe, Siberia, China and Tibet. Before monsoons birds roost and nest building activities start on the babool and kadam trees of Keoladeo National Park (Bharatpur). Water coming through the AjanBandh starts filling the various ponds and lakes of Keoladeo National Park (Bharatpur).

The story of Bharatpur Bird Sanctuary is incomplete without an account of the migratory waterfowl. The most prominent waterfowl coming to this park are bar headed and greylag geese. Ducks also create a lot of fluttering in the lakes. The ducks usually found here are pintail, widgeon, common shelduck, shoveler, garganey, teal, etc.

Attracted by the influx of the waterfowl the predatory birds-tawny eagles, spotted eagles short-toed eagles imperial eagles and fishing eagle also arrive. They all form the apex of the biological pyramid of the sanctuary and complete the avian food chain of the ecosystem. There are large herds of the nilgai, chital, wild boar and fear cows in addition to a few herds of sambar.

Visit to Bharatpur can be combined with FatehpurSikri and Agra. FatehpurSikri was once the proud capital of the Mughal Empire in the 16th century built by Emperor Akbar. One can also visit Agra for its famed  TajMahal.
