The Sri Lankan junglefowl (Gallus lafayettii sometimes spelled Gallus lafayetii), also known as the Ceylon junglefowl or Lafayette's junglefowl, is a member of the Galliformes bird order which is endemic to Sri Lanka, where it is the national bird.
Junglefowl are the only four living species of bird from the genus Gallus in the bird order Galliformes, and occur in parts of South and Southeast Asia.One of the species in this genus, the red junglefowl, is of historical importance as the direct ancestor of the domestic chicken, although the grey junglefowl, Sri Lankan junglefowl and green junglefowl are likely to have also been involved.

Fowl are birds belonging to one of two biological orders, namely the gamefowl or landfowl (Galliformes) and the waterfowl (Anseriformes).Anatomical and molecular similarities suggest these two groups are close evolutionary relatives; together, they form the fowl clade which is scientifically known as Galloanserae or Galloanseres (initially termed Galloanseri) (Latin gallus ("rooster") + ānser ...
Galliformes / ˌ ɡ æ l ɪ ˈ f ɔːr m iː z / is an order of heavy-bodied ground-feeding birds that includes turkeys, chickens, quail, and other landfowl.Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds.
The red junglefowl was the primary species to give rise to today's many breeds of domesticated chicken (G. g. domesticus); additionally, the related grey junglefowl (G. sonneratii), Sri Lankan junglefowl (G. lafayettii) and the Javanese green junglefowl (G. varius) have also contributed genetic material to the gene pool of the modern chicken.
The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name. For example, the zoological name for the human species is Homo sapiens. This is usually italicized in print or underlined ...
