The tract is very rich in avifauna. More than 250 bird species have been reported from Valmiki National Park (Valmiki Tiger Reserve). Almost all the bird species are likely to occur that are found in Dudhwa or the adjoining Sohagi Barwa Sanctuary in Uttar Pradesh . The common birds are Peafowls, Partridges (Black and Gray), Quails, Pigeon, Mynas, Bulbul, Hornbill, Parrot, Woodpickers, Vultures, Eagles, Flycatchers, Sunbirds, among others. Nepal Kalij Pheasant locally known as Churcha is also found. In the night several owls, owlets and nightjars can be easily seen. Globally threatened species such as the Swamp Francolin (Francolinus gularis) and Sociable Lapwing (Vanellus gregarius) have been reported from the area . The vulnerable Sarus Crane (Grus antigone) also occurs in small numbers . There were records of White-rumped Gyps bengalensis and Slender-billed vultures. Historical records of Bengal Florican (Houbaropsis bengalensis) from the general area also exist. A large roost of migratory Amur Falcons (Falco amurensis) was also discovered just outside the Reserve. Details of important observations are presented. Conservation issues are also discussed briefly and recommendations are made for the protection of habitats and birds.
