Possible
About 20% of wildlife watchers report a Gray-crowned Yellowthroat sighting in Rincón de la Vieja National Park on a given day, based on 211 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 66th most-seen of the 341 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May, August and October

Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Gray-crowned Yellowthroat sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Gray-crowned Yellowthroat is recorded against all the birds logged in Rincón de la Vieja National Park (211 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.
