Sri Lanka Junglefowl

Open encyclopedia reference

The Sri Lankan junglefowl (Gallus lafayettii), also known as the Ceylon junglefowl or Lafayette's junglefowl, is a member of the Galliformes bird order. It is a common endemic bird in Sri Lanka, where it is the national bird. It is closely related to the red junglefowl (G. gallus), the wild junglefowl from which the chicken was domesticated. However, it is even more closely related to the gray junglefowl. Sri Lankan junglefowl and red junglefowl diverged about 2.8 million years ago, whereas time of divergence between the Sri Lankan junglefowl and grey junglefowl was 1.8 million years ago.

Evidence of introgressive hybridization from Sri Lanka junglefowl has also been established in domestic chicken. The specific name of the Sri Lankan junglefowl commemorates the French aristocrat Gilbert du Motier, marquis de La Fayette (1757–1834).
