The crested partridge (Rollulus rouloul), also known as the crested wood partridge, roul-roul, red-crowned wood partridge, green wood quail, and green wood partridge is a gamebird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. It is the only member of the genus Rollulus.
This small partridge is a resident breeder in lowland rainforests in south Burma, south Thailand, Malaysia, Sumatra and Borneo. Its nest is a ground scrape lined with leaves, which is concealed under a heap of leaf litter. Five or six white eggs are incubated for 18 days.
Unusually for a galliform species, the young are fed bill-to-bill by both parents instead of pecking from the ground, and although precocial, they roost in the nest while small. The crested partridge is a rotund short-tailed bird, 25 cm (9.8 in) in length, with the male marginally larger than the female. Both sexes have a scarlet patch of bare skin around the eye and red legs without a spur or hind toe.
The male is metallic green above with glossy dark blue underparts and a brownish wing panel. The head is adorned with a tall red crest, a white forehead spot and black frontal bristles. The female has pea-green body plumage apart from the brown wing coverts. She has a slate-grey head with the bristles but no spot or crest. The bill is all-dark. Young birds are duller versions of the adult of the same sex. The song is a mournful whistled si-ul.
The crested partridge is usually seen singly or in pairs as it uses its feet to probe the forest floor for fruit, seeds and invertebrates. When disturbed, it prefers to run but if necessary it flies a short distance on its rounded wings.
There is some concern about the effect of habitat destruction on this bird, especially with regard to logging. However, it seems to be somewhat more adaptable than other southeast Asian pheasants. As of 2021, the crested wood partridge is evaluated as Vulnerable on the IUCN Red List of Threatened Species. It is listed on Appendix III of CITES. Wikipedia →

Rare
Under 5% of wildlife watchers report a Roulroul sighting in Taman Negara National Park on a given day, based on 62 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 162nd most-seen of the 293 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February, July–September and November–December
In those months about 10% of wildlife watchers report a Roulroul in Taman Negara National Park on a given day, against under 5% in January, March–June and October, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Roulroul sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Roulroul sightings, Taman Negara National Park has the highest daily chance: under 5%. Next come Way Kambas National Park (Indonesia, under 5%) and Danum Valley Conservation Area (Malaysia, under 5%).
Same family: Phasianidae
The closest relatives of the Roulroul that you can see in Taman Negara National Park (family Phasianidae, Pheasants, Grouse, and Allies) are Bornean Crested Fireback (about 20%), Great Argus (about 20%) and Red Junglefowl (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Roulroul is recorded against all the birds logged in Taman Negara National Park (62 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
