The oleaginous hemispingus (Hemispingus frontalis) is a species of bird in the family Thraupidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
The species’ underparts are dull-yellow in colour while it upperpart is olive-green.
The Oleaginous Hemispingus is a rather dull-colored member of its genus, predominantly dull yellow below and olive-green above, with a poorly marked yellowish supercilium, although this is more obvious in the Venezuelan races, especially those farthest from the main Andean chain. In a sense, it is well named; oleaginous—having the property or appearance of oil—is derived from olive, and this species is most certainly largely olive-colored. It is most liable to be confused with one of the smaller and finer-billed Basileuterus warblers, or the Superciliaried Hemispingus (Hemispingus superciliaris), which, as its name suggests, has a much more obvious supercilium. Its habits and behavior are typical of the genus as a whole.
14 cm; 14–20 g. Dingy, dull hemispingus with relatively slender bill. Nominate race has long, narrow, weakly indicated yellowish supercilium (most obvious in front of eye); crown and entire upperparts, including upperwing-coverts and tail, dull dirty olive, flight-feathers narrowly edged cinnamon; dingy olive-yellow below, more olive on sides, tinged cinnamon on undertail-coverts; iris dark brown; bill dusky grey; legs pale brownish to brownish-grey. Sexes similar. Juvenile lacks supercilium, is even duller and dingier than adult; immature like adult but duller. N races differ from nominate in generally brighter coloration: hanieli has brighter and more pronounced yellow supercilium, and is more yellow-ochre below; iterata differs from previous in having supercilium and throat tinged rich buff to orange-buff; ignobilis has greenish-yellow supercilium, with pale buffy throat better demarcated from breast than in other races; flavidorsalis has more olive upperparts, flight-feathers edged olive-green, and supercilium and throat with buff-yellow tinge.
