Sprawling over an area of 2073 square kilometers, the marshy land of the sanctuary lying along the river Ganga, is home to a huge variety of animal species as well as flora and fauna.
According to an estimate, there are more than 350 bird species including the painted stork, sarus crane, black and white necked stork, night birds of prey such as great Indian horned owl, jungle owlet, woodpecker, kingfisher, bee eater and bulbuls.
The sanctuary contains great many niches of faunal wealth. There are mammals, reptiles including snakes and lizards, amphibians such as frogs and toads, fishes and colorful butterflies; invertebrate including scorpions, centipedes, wasps, bees and above all the NationalBird peacock which is found here in large numbers.
