Sri Lanka junglefowl roost in trees, usually singly but sometimes in pairs or family parties, and spend much of the day on the ground (3), foraging in the morning and evening along open tracks in the forest. This bird feeds on grain, weed seeds, berries, flowers, various succulent leaves and buds, and a large proportion of small animals, such as termites, beetles, woodlice, crickets and centipedes (2) (3). Animal matter forms the bulk of the diet for chicks (3).
While the main breeding season is from February to May, a second clutch is often laid in August to September, and breeding appears to go on throughout the year (2) (3). Nests are constructed in a variety of locations, but typically occur on the ground amongst bushes or under logs, although use of a deserted squirrel and crows nest have been recorded, several metres above the ground. Clutches normally consist of two to four eggs, incubated for 20 to 21 days (in captivity) (2). The chicks are well developed and learn to scratch for food as soon as they leave the nest, although they will instantly scatter and hide at their mother’s alarm call (3).
