Desert National Park, Rajasthan, India. The Desert National Park is situated in the west Indian state of Rajasthan near the town of Jaisalmer. This is one of the largest national parks, covering an area of 3162 sq. km. The Desert National Park is an excellent example of the ecosystem of the Thar Desert. Sand dunes form around 20% of the Park. The major landform consists of craggy rocks and compact salt lake bottoms, intermedial areas and fixed dunes. Despite a fragile ecosystem there exists an abundance of birdlife. The endangered great Indian bustard is one magnificent bird found in relatively fair numbers. It migrates locally in different seasons. The region is a haven for migratory and resident birds of the desert. One can see many eagles, harriers, falcons, buzzards, kestrel and vultures. Short- toed eagles, tawny eagles, spotted eagles, lagger falcons and kestrels are the commonest of these. Sand grouse are spotted near small ponds or lakes.
