Near-Threatened A small broadbill of the Malay Peninsula (ssp. continentis), Sumatra, Borneo, and islands in between (nominate viridis), and some of the Barisan Is. off W Sumatra (ssp. siberu). Inconspicuous, staying motionless for long periods in the dense middle and upper storey of primary or mature secondary forest. Less widely distributed and less catholic in its habitat choice as Eurylaimus ochromalus [elsewhere on this site], but after clearance of much of the lowland forest will probably survive in hill forest and in larger patches of remnant lowland forest.

Remarks
The races differ mainly in size, as the supposed colour differences of the plumage (purer green vs bluer-green) depend largely on wear, birds becoming bluer when worn. According to the literature, nominate viridis is smaller (wing male 92.5-100.5 mm, female 98-106 mm), and continentis is larger (male 98-106 mm, female 107-113 mm) (Lambert & Woodcock 1996). Our birds from NE Sumatra have wing 92-96 mm (male) and 96-100 mm (female), the males from Borneo have wing 98 & 99 mm, while the birds from captivity have wing 100 & 102 (males) and 107 mm (female). Apparently, the ZMA birds from Sumatra and Borneo are nominate viridis, while the captive birds are continentis. The species was frequently imported in the 1980-1990s in the Netherlands, apparently mostly from western Malaysia. Whether siberu is valid has to be checked with specimens: it is said to be large as continentis or larger still, and with darker and more bluish-green plumage (Lambert & Woodcock 1996).

De Bussy's 233c, female, 15 Jun 1916, Basilam [= Pesilam (c. 03°48'N, 98°20'E)], Langkat, NE Sumatra, has never reached the ZMA.
