Thecrested partridge (Rollulus rouloul), also known as thecrested wood partridge,roul-roul,red-crowned wood partridge,green wood quail, andgreen wood partridge is agamebird in thepheasant familyPhasianidae of the orderGalliformes, gallinaceous birds. It is theonly member of the genusRollulus.
This smallpartridge is a resident breeder in lowlandrainforests in southBurma, southThailand,Malaysia,Sumatra andBorneo. Its nest is a ground scrape lined with leaves, which is concealed under a heap ofleaf litter. Five or six whiteeggs are incubated for 18 days.
Unusually for agalliform species, the young are fed bill-to-bill by both parents instead of pecking from the ground, and althoughprecocial, they roost in thenest 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 wingcoverts. She has a slate-grey head with the bristles but no spot or crest. Thebill is all-dark. Young birds are duller versions of the adult of the same sex. The song is a mournful whistledsi-ul.
The crested partridge is usually seen singly or in pairs as it uses its feet to probe theforest floor forfruit,seeds andinvertebrates.[3] When disturbed, it prefers torun but if necessary it flies a short distance on its rounded wings.
There is some concern about the effect ofhabitat destruction on this bird, especially with regard to logging. However, it seems to be somewhat more adaptable than othersoutheast Asian pheasants. As of 2021, the crested wood partridge is evaluated as Vulnerable on theIUCN Red List of Threatened Species.[1] It is listed on Appendix III ofCITES.
