Crested partridge
Species of partridge from southeast Asia
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.
Begin with the source’s own compact description: “Crested partridge” is species of partridge from southeast Asia. The dossier treats that line as a proposition to test through Crested, partridge and Species, not as a finished interpretation.
Why this record matters
The phrase “species of partridge from southeast Asia” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 6, 2026. The linked authority identifier is Q763130. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
