The Indian Post has issued a series of four stamps dedicated to the endemic species living on the territory of India: Bugun Liocichla, Nicobar Megapode, Hoolock gibbon and Venated gliding frog.
The Bugun Liocichla is a passerine bird species from the Old World babbler family. First spotted in 1995, it was described as a new species in 2006 by Ramana Athreya. The description was made without the collection of a type specimen as they were too few to risk killing one. It is thought to be an endangered species, with the only known population estimated to consist of 14 individuals and commercial development threatening the habitat of this population.
The Nicobar Megapode is a megapode found in some of the Nicobar Islands (India). Like other megapodes relatives, it builds a large mound nest with soil and vegetation, with the eggs hatched by the heat produced by decomposition. Being restricted to small islands and threatened by hunting, the species is vulnerable to extinction.
The Hoolock gibbons are primate species from the family of the gibbons. Hoolocks are the second-largest of the gibbons, after the siamang. They reach a size of 60 to 90 cm and weigh 6 to 9 kg. The sexes are about the same size, but they differ considerably in coloration: males are black-colored with remarkable white brows, while females have a grey-brown fur, which is darker at the chest and neck. White rings around their eyes and mouths give their faces a mask-like appearance.
Venated gliding frog has the ability to achieve gliding flight. That is, it can descend at an angle of less than 45
