The marble-faced bristle tyrant (Pogonotriccus ophthalmicus) is a species of passerine bird in the family Tyrannidae, the tyrant flycatchers.

That genus was later merged into genus Phylloscartes. Beginning in 2016 taxonomic systems resurrected Pogonotriccus for this species and a few others.

Rare
Under 5% of wildlife watchers report a Marble-Faced Bristle-Tyrant sighting in Podocarpus National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 278th most-seen of the 446 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report a Marble-Faced Bristle-Tyrant in Podocarpus National Park on a given day, against under 5% in March to January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Marble-Faced Bristle-Tyrant 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 Marble-Faced Bristle-Tyrant sightings, Podocarpus National Park ranks 5th at under 5%. The best odds are in Henri Pittier National Park (Venezuela, about 10%), Los Nevados National Natural Park (Colombia, about 10%) and Amboró National Park (Bolivia, under 5%).
GBIF citizen-science records
It is estimated from how often the Marble-Faced Bristle-Tyrant is recorded against all the birds logged in Podocarpus National Park (28 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.
