The blue finch or yellow-billed blue finch (Rhopospina caerulescens) is a Near Threatened species of bird in the family Thraupidae, the tanagers and allies. It is found in Bolivia and Brazil. The blue finch was formally described in 1830 with the binomial Tanagra caerulescens. It was later reassigned to the genus Porphyrospiza. That genus was long in family Emberizidae which at the time held many New and Old World species. There it was grouped with the cardinalines which were later separated as the family Cardinalidae. A study published in 2007 showed that the genus belonged in its present tanager family Thraupidae. Beginning in 2019 most taxonomic systems began reassigning the blue finch to the resurrected genus Rhopospina that had been erected in 1851. However, as of late 2025 BirdLife International's Handbook of the Birds of the World retains it as the only species in Porphyrospiza.
The blue finch is monotypic. The blue finch is about 12.5 cm (4.9 in) long and weighs about 13 g (0.46 oz). It is a slim bird with a long tail and a long bill. The species is sexually dimorphic. Adult males are almost entirely bright indigo-blue. They have... Wikipedia →

Possible
About 20% of wildlife watchers report a Blue Finch sighting in Serra da Canastra National Park on a given day, based on 97 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 106th most-seen of the 294 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.
March
In that month about 30% of wildlife watchers report a Blue Finch in Serra da Canastra National Park on a given day, against about 10% in February, April and July, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Blue 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.
Yes
Of the 3 parks where we can rate Blue Finch sightings, Serra da Canastra National Park has the highest daily chance: about 20%. Next come Chapada Diamantina National Park (Brazil, about 10%) and Chapada dos Guimarães National Park (Brazil, under 5%).

GBIF citizen-science records
It is estimated from how often the Blue Finch is recorded against all the birds logged in Serra da Canastra National Park (97 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.
