Bharatpur Bird Sanctuary, presently known as Keoladeo Ghana National Park or simply Keoladeo National park is a well known sanctuary of avifauna in the city of Bharatpur in Rajasthan. It is seen to have hundreds of varieties of birds migrating during the summers. During the peak migratory season, more than 230 bird species arrive here. Besides becoming a major tourist centre, the national park is known for the ornithologists who visit here to study the birds during their season of hibernation. In 1971, it was announced as a sanctuary which was protected. Later, it was proclaimed as a World Heritage Site.
Keoladeo Ghana National Park is a wetland, made and managed by men and is also a national park. Due to this reserve area, Bharatpur is protected from floods and simultaneously gives enough grounds for the cattle to graze, which in earlier days was used for hunting waterfowls. This reserve area extends to about 29 kms and is named by local people as Ghana, where woodlands, dry grasslands, wetlands and woodland swamps are scattered in a mosaic pattern. Such diversity in the landscape makes it suitable as a home to birds of 366 species, flora of 379 species, snakes of 13 species, amphibians of 7 species, fishes of 50 species, lizards of 5 species, turtles of 7 species and various other invertebrates. Plenty of waterfowls arrive here every year for winter breeding and stay. In terms of bird population, this is one of the most dense and rich areas. Resident birds as well as those arriving due to migration nest in the national park. In the past, the presently extinct Siberian Cranes used to come here in the winters. Sir Peter Scott places Keoladeo Sanctuary as the best areas for birds in the world.
