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 Manu National Park on a given day, based on 204 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 269th most-seen of the 641 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
January, May–September and November
In those months about 10% of wildlife watchers report a Dusky-capped Greenlet in Manu National Park on a given day, against under 5% in February–April, October and December, 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.
Among the best
Of the 5 parks where we can rate Dusky-capped Greenlet sightings, Manu National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Tambopata National Reserve (Peru, about 10%) and Yasuní National Park (Ecuador, about 10%).
GBIF citizen-science records
It is estimated from how often the Dusky-capped Greenlet is recorded against all the birds logged in Manu National Park (204 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.
