We were on a business trip driving through a town called Bharthpur in Rajasthan. Bharthpur has an amazing national park which is also a bird sanctuary called the Keoladeo National Park.
Interesting Bharathpur Park is over 250 years old and has between 250-350 species of birds. This is the ONLY World Heritage site in Rajasthan.
According to a UNESCO investigation, the park is under serious threat due to lack of water supply and environmental changes. Since most of the birds at Bharthpur are water birds, they depend on the monsoons and open landscape for their existance. Over the last 10-15 years, the drop in monsoons, the reduce water supply from natural water sources (from construction of dams) and the growth of new vegetation is seriously affecting the bird population. A 2008 UNSECO study points out some of these issues. One serious issue pointed out is of the endangered Siberian Crane species which has always migrated and spotted at the park, is not seen since 2002.
There are lots of resources online on how to get there. Our itinerary was quite convoluted and not aimed at traveling to Bharthpur in particular so I cannot add much value here. One thing I can talk about is the lack of hotel accommodation. We had a tough time making a booking over the phone and ended up in a guest house / rest house run by an ex-army gentleman. He was a great host and very accommodating but the facilities were terrible. The key issues for a place this beautiful is that there are few clean hotels and even fewer clean places to eat.
