The crested partridge, also known as the “roul roul,” is a small bird native to Southeast Asia. The species is sexually dimorphic, with males being slightly larger and distinguished by a reddish crest, while females have greenish plumage and brown wings. Both sexes have a distinctive red ring around the eye. Crested partridges spend much of their time foraging on the forest floor for fruit, seeds and invertebrates, taking short flights when threatened.

These birds may be found alone or in groups of up to 15 individuals during the breeding season and use a distinctive whistling “si-ul” call to communicate with one another. Crested partridges sometimes follow monkeys and wild pigs, feeding on fruits that these larger animals have opened or dropped, allowing the birds to access fruits they could not otherwise eat.
