Keoladeo National Park or Keoladeo Ghana National Park formerly known as the Bharatpur Bird Sanctuary in Bharatpur, Rajasthan, India is a famous avifauna sanctuary that hosts thousands of birds, especially during the winter season. Over 230 species of birds are known to be resident. It is also a major tourist centre with scores of ornithologists arriving here in the hibernal season. It was declared a protected sanctuary in 1971. It is also a World Heritage Site.Keoladeo Ghana National Park is a man-made and man-managed wetland and one of the national parks of India. The reserve protects Bharatpur from frequent floods, provides grazing grounds for village cattle, and earlier was primarily used as a waterfowl hunting ground. The 29 km2 (11 sq mi) reserve is locally known as Ghana, and is a mosaic of dry grasslands, woodlands, woodland swamps and wetlands. These diverse habitats are home to 366 bird species, 379 floral species, 50 species of fish, 13 species of snakes, 5 species of lizards, 7 amphibian species, 7 turtle species and a variety of other invertebrates. Every year thousands of migratory waterfowl visit the park for wintering and breeding. The sanctuary is one of the richest bird areas in the world and is known for nesting of resident birds and visiting migratory birds including water birds. The rare Siberian cranes used to winter in this park but this central population is now extinct. According to founder of the World Wildlife Fund Peter Scott, Keoladeo National Park is one of the world’s best bird areas.
The sanctuary was created 250 years ago and is named after a Keoladeo (Shiva) temple within its boundaries. Initially, it was a natural depression; and was flooded after the Ajan Bund was constructed by Maharaja Suraj Mal, then the ruler of the princely state of Bharatpur, between 1726–1763. The bund was created at the confluence of two rivers, the Gambhir and Banganga. The park was a hunting ground for the Maharajas of Bharatpur, a tradition dating back to 1850, and duck shoots were organised yearly in honour of the British viceroys. In one shoot alone in 1938, over 4,273 birds such as mallards and teals were killed by Lord Linlithgow, then Viceroy of India.The park was established as a national park on 10 March 1982. Previously the private duck shooting preserve of the Maharaja of Bharatpur since the 1850s, the area was designated as a bird sanctuary on 13 March 1976 and a Ramsar site under the Wetland Convention in October 1981.The last big shoot was held in 1964 but the Maharajah retained shooting rights until 1972. In 1985, the Park was declared a World Heritage Site under the World Heritage Convention. It is a reserve forest under the Rajasthan Forest Act, 1953 and therefore, is the property of the State of Rajasthan of the Indian Union. In 1982, grazing was banned in the park, leading to violent clashes between local farmers and the government.
