The dusky-capped greenlet (Pachysylvia hypoxantha) is a species of bird in the family Vireonidae, the vireos, greenlets, and shrike-babblers. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. The dusky-capped greenlet was originally described in 1868 as Hylophilus hypoxanthus. For a time early in the twentieth century it was considered a subspecies of the golden-fronted greenlet (P. aurantiifrons) but beginning in the 1930s it attained its status as a full species.
The dusky-capped greenlet has these six subspecies: Pachysylvia hypoxantha hypoxantha (Pelzeln, 1868) Pachysylvia hypoxantha fuscicapillus (Sclater, PL & Salvin, 1880) Pachysylvia hypoxantha flaviventris (Cabanis, 1873) Pachysylvia hypoxantha icterica (Bond, J, 1953)
Pachysylvia hypoxantha albigula Chapman, 1921 Pachysylvia hypoxantha inornata Snethlage, E, 1914 Some mid-twentieth century authors treated P. h. inornata as a subspecies of the brown-headed greenlet (Hylophilus brunneiceps). Subspecies P. h. flaviventris was described as a full species and often treated that way until the mid-twentieth century.
The dusky-capped greenlet is 11.5 to 12 cm... Wikipedia →

With luck
About 10% of wildlife watchers report a Dusky-capped Greenlet sighting in Tambopata National Reserve on a given day, based on 374 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 121st most-seen of the 550 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
February and July–August
In those months about 20% of wildlife watchers report a Dusky-capped Greenlet in Tambopata National Reserve on a given day, against under 5% in March and June, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Dusky-capped Greenlet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 5 parks where we can rate Dusky-capped Greenlet sightings, Tambopata National Reserve has the highest daily chance: about 10%. Next come Yasuní National Park (Ecuador, about 10%) and Manu National Park (Peru, about 10%).
GBIF citizen-science records
It is estimated from how often the Dusky-capped Greenlet is recorded against all the birds logged in Tambopata National Reserve (374 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.
