Rare
Under 5% of wildlife watchers report a Tawny-throated Leaftosser sighting in La Tigra National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 109th most-seen of the 176 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report a Tawny-throated Leaftosser in La Tigra National Park on a given day, against under 5% in June–August and November–April, the lowest months.

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.
2nd of 14
Of the 14 parks where we can rate Tawny-throated Leaftosser sightings, La Tigra National Park ranks 2nd at under 5%. The best odds are in El Triunfo (Mexico, about 20%).

GBIF citizen-science records
It is estimated from how often the Tawny-throated Leaftosser is recorded against all the birds logged in La Tigra National Park (15 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.
