Rare
Under 5% of wildlife watchers report a Plain Antvireo sighting in Arenal Volcano National Park on a given day, based on 660 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 220th most-seen of the 503 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.
September to December
In those months about 10% of wildlife watchers report a Plain Antvireo in Arenal Volcano National Park on a given day, against under 5% in January to August, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Plain Antvireo 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 30
Of the 30 parks where we can rate Plain Antvireo sightings, Arenal Volcano National Park ranks 16th at under 5%. The best odds are in Serra dos Órgãos National Park (Brazil, about 40%), Amboró National Park (Bolivia, about 40%) and Iguazú National Park (Argentina, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Plain Antvireo is recorded against all the birds logged in Arenal Volcano National Park (660 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.
