Rare
Under 5% of wildlife watchers report a Black-throated Green Warbler sighting in Arenal Volcano National Park on a given day, based on 299 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 280th most-seen of the 503 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-throated Green Warbler in Arenal Volcano National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-throated Green Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
42nd of 48

GBIF citizen-science records
It is estimated from how often the Black-throated Green Warbler is recorded against all the birds logged in Arenal Volcano National Park (299 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.
