The endemic Sri Lankan junglefowl (Gallus lafayettii) inhabits forests or dense scrub areas in the dry zone. Ground-dwelling, they seek cover in trees when threatened by predators and are commonly heard calling in the early morning. Their diet consists of grain, seeds, berries, leaves, buds, and small animals like crickets, termites, and centipedes.

The Sri Lankan junglefowl is a sexually dimorphic species, with males displaying vibrant orange-red plumage and a purplish-blue tail and wings, while females are smaller and primarily brown.
