Identification: Distinguished from Common Moorhen by bigger size, dark purplish blue overall plumage, red stout bill, frontal shield and legs, whitish undertail-coverts and blackish-brown wings. Juvenile resembles adult but has paler plumage and duller frontal shield. Distinguished from the similar Black-backed Swamphen by generally greyer upperparts and head, as well as usually bigger frontal shield that features raised ridges by the side. Hybrids of the two species may occur but confirmatory evidence is lacking, and their taxonomic relationships are also being debated.
