Rare
Under 5% of wildlife watchers report a Brown-capped Vireo sighting in Irazú Volcano National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 94th most-seen of the 121 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report a Brown-capped Vireo in Irazú Volcano National Park on a given day, against under 5% in June to March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Brown-capped Vireo sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
16th of 19
Of the 19 parks where we can rate Brown-capped Vireo sightings, Irazú Volcano National Park ranks 16th at under 5%. The best odds are in Volcán Barú National Park (Panama, about 40%), Henri Pittier National Park (Venezuela, about 30%) and Los Quetzales National Park (Costa Rica, about 20%).
GBIF citizen-science records
It is estimated from how often the Brown-capped Vireo is recorded against all the birds logged in Irazú Volcano National Park (16 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.
