Rare
Under 5% of wildlife watchers report a Black-and-rufous Warbling-Finch sighting in Iberá National Park on a given day, based on 40 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 224th most-seen of the 284 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
May and August
In those months about 10% of wildlife watchers report a Black-and-rufous Warbling-Finch in Iberá National Park on a given day, against under 5% in June–July and September–April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-and-rufous Warbling-Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Black-and-rufous Warbling-Finch sightings, Iberá National Park ranks 2nd at under 5%. The best odds are in El Palmar National Park (Argentina, about 10%).

GBIF citizen-science records
It is estimated from how often the Black-and-rufous Warbling-Finch is recorded against all the birds logged in Iberá National Park (40 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.
