The oleaginous hemispingus (Sphenopsis frontalis) is a species of bird in the family Thraupidae. It is found in Colombia, Ecuador, Peru, and Venezuela. It inhabits wet montane rainforests at elevations of 1,400–2,700 m (4,600–8,900 ft). It is 14 cm (5.5 in) long and weighs 14–20 g (0.5–0.7 oz) on average. It has dull yellow underparts and olive-green upperparts. It is classified as being of least concern by the IUCN.
The oleaginous hemispingus was formally described as Hylophilus frontalis by the Swiss naturalist Johann Jakob von Tschudi in 1844 based on specimens collected from the Peruvian Andes. The specific epithet is derived from the Latin word frontalis, meaning "fronted". The common name means "having...appearance of oil", referring to its olive coloration.
The oleaginous hemispingus has five recognised subspecies. These subspecies are fairly well-differentiated morphologically and exhibit clinal variation in Venezuela as they get further from the Andes. Wikipedia →

Rare
Under 5% of wildlife watchers report an Oleaginous Hemispingus sighting in Los Nevados National Natural Park on a given day, based on 222 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 171st most-seen of the 424 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July–September and December
In those months about 10% of wildlife watchers report an Oleaginous Hemispingus in Los Nevados National Natural Park on a given day, against under 5% in January–June and October–November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Oleaginous Hemispingus sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Oleaginous Hemispingus sightings, Los Nevados National Natural Park has the highest daily chance: under 5%. Next come Henri Pittier National Park (Venezuela, under 5%) and Farallones de Cali National Natural Park (Colombia, under 5%).
GBIF citizen-science records
It is estimated from how often the Oleaginous Hemispingus is recorded against all the birds logged in Los Nevados National Natural Park (222 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
