Under 5% of wildlife watchers report a Black-faced Antbird sighting in Madidi National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 215th most-seen of the 239 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.
May
In that month about 20% of wildlife watchers report a Black-faced Antbird in Madidi National Park on a given day, against under 5% in January, April and July–November, the lowest months. March and December have too few records to rate.

Of the 8 parks where we can rate Black-faced Antbird sightings, Madidi National Park ranks 7th at under 5%. The best odds are in Sierra de la Macarena National Park (Colombia, about 20%), Tambopata National Reserve (Peru, about 10%) and Manu National Park (Peru, about 10%).
GBIF citizen-science records
It is estimated from how often the Black-faced Antbird is recorded against all the birds logged in Madidi National Park (5 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.
