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 →

Rare
Under 5% of wildlife watchers report a Red-rumped Cacique sighting in São Paulo on a given day, based on 100 verified sightings from GBIF citizen-science data. It is the 190th most-seen of the 353 birds we can rate there. Over three days the chance rises to under 5%, and over a week 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 Red-rumped Cacique in São Paulo 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 Red-rumped Cacique sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 cities where we can rate Red-rumped Cacique sightings, São Paulo ranks 5th at under 5%. The best odds are in Curitiba (Brazil, about 40%), Asuncion (Paraguay, about 10%) and Santos (Brazil, under 5%).
Same family: Icteridae
The closest relatives of the Red-rumped Cacique that you can see in São Paulo (family Icteridae, New World Blackbirds and Orioles) are Shiny Cowbird (about 10%) and Chestnut-capped Blackbird (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-rumped Cacique is recorded against all the birds logged in São Paulo (100 verified sightings), 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.
