Possible
About 30% of wildlife watchers report a White-bellied Wren sighting in Tikal National Park on a given day, based on 615 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 53rd most-seen of the 300 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the White-bellied Wren is recorded against all the birds logged in Tikal National Park (615 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.
