Possible
About 30% of wildlife watchers report a Black-hooded Antshrike sighting in Marino Ballena National Park on a given day, based on 530 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 303 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-hooded Antshrike sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 8
Of the 8 parks where we can rate Black-hooded Antshrike sightings, Marino Ballena National Park ranks 5th at about 30%.

GBIF citizen-science records
It is estimated from how often the Black-hooded Antshrike is recorded against all the birds logged in Marino Ballena National Park (530 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.
