Rare
Under 5% of wildlife watchers report a Fulvous Antshrike sighting in Yasuní National Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 412th most-seen of the 533 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Fulvous Antshrike in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Fulvous Antshrike sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Yasuní National Park, in our data
Yasuní National Park is the only park on Wallace's Line with enough records to rate Fulvous Antshrike sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Thamnophilidae

GBIF citizen-science records
It is estimated from how often the Fulvous Antshrike is recorded against all the birds logged in Yasuní National Park (38 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.
