Likely
About 60% of wildlife watchers report a Gray-breasted Wood-Wren sighting in Volcán Barú National Park on a given day, based on 1,296 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 296 birds we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Gray-breasted Wood-Wren is recorded against all the birds logged in Volcán Barú National Park (1,296 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.
