With luck
About 10% of wildlife watchers report a Yellow-crowned Elaenia sighting in Yasuní National Park on a given day, based on 151 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 250th most-seen of the 533 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Yellow-crowned Elaenia is recorded against all the birds logged in Yasuní National Park (151 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.
