Among all groups of animals in the world, birds are most liked owing to their rich colour, song, easy recognition and liveliness. Moreover, birds are present everywhere. We can see birds in city gardens, crop fields, forests, grasslands and wetlands.

Dudhwa National Park, together with Kishanpur and Katerniaghat Wildlife Sanctuaries, represent the best natural forests and grasslands left in the Terai region of Uttar Pradesh.

The three protected areas, being the last viable home of the Royal Bengal Tiger in the state, have been jointly constituted into Dudhwa Tiger Reserve. There is an enviable bird life with over 450 resident as well as migratory species.

For birds observation, a binocular is a great help as it allows unobtrusive observation without disturbing the bird by approaching too close. A binocular with a magnification of 8 to 10X and field of view 5.5 degree to 8 degree is usually adequate. For waterbirds, a spotting scope or telescope mounted on a tripod can be great help. The park has rich bird life, with over 350 species, including the swamp francolin, great slaty woodpecker and Bengal florican. Dudhwa also boasts a range of migratory birds that settle here during winters. It includes among others, painted storks, black and white necked storks, sarus cranes, woodpeckers, barbets, kingfishers, minivets, bee-eaters, bulbuls and varied night birds of prey.

There are also drongos, barbets, cormorants, ducks, geese, hornbills, bulbuls, teal, woodpeckers, heron, bee-eaters, minivets, kingfishers, egrets, orioles, painted storks, owls. Dudhwa's birds in particular are a delight for any avid bird watcher where bengal florican is most popular between bird watchers.
