The red-rumped cacique (Cacicus haemorrhous) is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in every mainland South American country except Chile. In 1760 the French zoologist Mathurin Jacques Brisson included a description of the red-rumped cacique in his Ornithologie based on a specimen collected in Cayenne in French Guiana. He used the French name Le cassique rouge and the Latin name Cassicus ruber. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognized by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the red-rumped cacique. Linnaeus included a brief description, coined the binomial Oriolus haemorrhous and cited Brisson's work. The specific epithet haemorrhous combines the Ancient Greek words haima "blood" and orrhos "rump". The red-rumped cacique is now the type species in the genus Cacicus that was introduced by the French naturalist... Wikipedia →

About 50% of wildlife watchers report a Red-rumped Cacique sighting in Serra dos Órgãos National Park on a given day, based on 298 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 336 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Red-rumped Cacique is recorded against all the birds logged in Serra dos Órgãos National Park (298 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.
