Possible
About 20% of wildlife watchers report a Tawny-throated Leaftosser sighting in El Triunfo on a given day, based on 32 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th most-seen of the 221 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 50% of wildlife watchers report a Tawny-throated Leaftosser in El Triunfo on a given day, against about 10% in May, July and November–February, the lowest months. That is one of El Triunfo's driest months, with about 65 mm of rain against 420 mm in June. June has too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Tawny-throated Leaftosser 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 14 parks where we can rate Tawny-throated Leaftosser sightings, El Triunfo has the highest daily chance: about 20%. Next come La Tigra National Park (Honduras, under 5%) and Darién National Park (Panama, under 5%).
Same family: Furnariidae

GBIF citizen-science records
It is estimated from how often the Tawny-throated Leaftosser is recorded against all the birds logged in El Triunfo (32 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.
