The ochre-crowned greenlet (Tunchiornis ochraceiceps) is a species of bird in the family Vireonidae, the vireos, greenlets, and shrike-babblers. It is found in Mexico, in every Central American country except El Salvador, and in Colombia and Ecuador. This species was formerly known as the tawny-crowned greenlet and was considered to be conspecific with the Para greenlet, Guianan greenlet and rufous-fronted greenlet.
The ochre-crowned greenlet was formally described in 1860 as Hylophilus ochraceiceps by the English zoologist Philip Sclater. The specimen had been collected in the state of Oaxaca of southwestern Mexico by the French ornithologist Adolphe Boucard. The specific epithet combines the Modern Latin ochraceus meaning "ochraceous" with -ceps meaning "-capped". The species is now placed in the genus Tunchiornis that was introduced in 2014.
The IOC and AviList recognize these five subspecies: Wikipedia →
Rare
Under 5% of wildlife watchers report a Tawny-crowned Greenlet sighting in Tapantí-Macizo de la Muerte National Park on a given day, based on 184 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 265th most-seen of the 467 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Tawny-crowned Greenlet in Tapantí-Macizo de la Muerte National Park on a given day, against under 5% in November to September, the lowest months. That is one of Tapantí-Macizo de la Muerte National Park's wettest months, with about 570 mm of rain against 160 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Tawny-crowned Greenlet sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
17th of 30
Of the 30 parks where we can rate Tawny-crowned Greenlet sightings, Tapantí-Macizo de la Muerte National Park ranks 17th at under 5%. The best odds are in Cockscomb Basin Wildlife Sanctuary (Belize, about 30%), Corcovado National Park (Costa Rica, about 20%) and Tikal National Park (Guatemala, about 20%).
GBIF citizen-science records
It is estimated from how often the Tawny-crowned Greenlet is recorded against all the birds logged in Tapantí-Macizo de la Muerte National Park (184 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.
