The dusky-tailed flatbill (Ramphotrigon fuscicauda) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. The genus Ramphotrigon was long thought to be closely related to genera Tolmomyias and Rhynchocyclus, whose members also have wide bills. However, studies published in the early 2000s found that it is more closely related to genus Myiarchus.
The dusky-tailed flatbill is monotypic. The dusky-tailed flatbill is 15.5 to 16.5 cm (6.1 to 6.5 in) long and weighs about 16.5 to 20.5 g (0.58 to 0.72 oz). The sexes have the same plumage. Adults have a dark olive crown, grayish lores, and a thin yellow-green line behind the lores and under the eye on an otherwise dark olive face. Their upperparts are mostly dark olive with slightly lighter uppertail coverts. Their wings are mostly fuscous-black with thin buffy olive edges on the primaries and old gold edges on the secondaries and tertials. Their wing coverts have wide rufous brown or cinnamon edges that show as two wing bars. Their tail is brownish fuscous-black with thin buffy citrine edges on the feathers. Their... Wikipedia →

Rare
Under 5% of wildlife watchers report a Dusky-tailed Flatbill sighting in Tambopata National Reserve on a given day, based on 114 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 291st most-seen of the 550 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February, May and August
In those months about 10% of wildlife watchers report a Dusky-tailed Flatbill in Tambopata National Reserve on a given day, against under 5% in March–April, June–July and September–January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Dusky-tailed Flatbill sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Dusky-tailed Flatbill sightings, Tambopata National Reserve has the highest daily chance: under 5%. Next come Manu National Park (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Dusky-tailed Flatbill is recorded against all the birds logged in Tambopata National Reserve (114 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.
