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 →

Rare
Under 5% of wildlife watchers report a Dusky-capped Greenlet sighting in Anavilhanas National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 258th most-seen of the 291 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Dusky-capped Greenlet in Anavilhanas National Park on a given day, against under 5% in September to July, the lowest months. That is one of Anavilhanas National Park's driest months, with about 75 mm of rain against 340 mm in March.
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.
5th of 5
Of the 5 parks where we can rate Dusky-capped Greenlet sightings, Anavilhanas National Park ranks 5th at under 5%. The best odds are in Tambopata National Reserve (Peru, about 10%), Yasuní National Park (Ecuador, about 10%) and Manu National Park (Peru, about 10%).
Same genus: Hylophilus
The closest relatives of the Dusky-capped Greenlet that you can see in Anavilhanas National Park (genus Hylophilus, Scrub Greenlets) are Gray-chested Greenlet (about 20%) and Brown-headed Greenlet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dusky-capped Greenlet is recorded against all the birds logged in Anavilhanas National Park (6 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.
