Professional bird watchers will perhaps better, but Sultanpur may rank only 2nd after Bharatpur in areas around Delhi for bird watching. Thankfully, Haryana government has separated the resort (which has nice lawns and an average restaurant) from the sanctuary. The sanctuary is really a natural environ, a large water body with bund around it. And we saw a virtual bird paradise..we could see Painted Stork, Black headed Ibis, black ibis, black crane, wooly headed crane, purple heron, grey hornbill, kingfishers, cormorants, owls, snake bird, ballards, geese, coots and plenty of other water birds. One could spend hours there. You could also see some deer species. PLEASE DO NOT GO TO CROWD THE PLACE IF YOU FEEL BORED WITH BIRDS AND ANIMALS. There is no urban kind of entertainment there.
