The blue-black grosbeak (Cyanoloxia cyanoides) is a species of songbird in the family Cardinalidae. The South American Classification Committee of the American Ornithological Society places this species in genus Cyanoloxia. In addition, in 2018 the committee split the eastern lowland population into a new species, the Amazonian grosbeak (Cyanoloxia rothschildii).
The blue-black grosbeak is found in the family Cardinalidae, within the order Passeriformes. Although it is still sometimes placed in the genus Cyanocompsa, it was found that this genus is paraphyletic and contains members of the genus Amaurospiza and Cyanoloxia.
There are three subspecies in this taxa: Cyanoloxia cyanoides cyanoides, Cyanoloxia cyanoides caerulescens, and Cyanoloxia cyanoides concreta. Although these three subspecies are very similar, there are slight differences between them. Males all have dark blue plumage, however, C.c. concreta has the darkest of the three and is also the largest. Next, in terms of size and coloration, is C.c. caerulescens, followed by C.c. cyanoides, which has the smallest size and brightest plumage.
Originally there was a fourth subspecies, C.c. rothschildii... Wikipedia →

With luck
About 10% of wildlife watchers report a Blue-black Grosbeak sighting in Chagres National Park on a given day, based on 161 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 108th most-seen of the 372 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Blue-black Grosbeak is recorded against all the birds logged in Chagres National Park (161 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.
