Red-rumped cacique

The red-rumped cacique (Cacicus haemorrhous) is a species of bird in the family Icteridae. It is a species of the Amazon Basin and the Guyanas in northern South America, and is only coastal there in the Guyanas and the Amazon River outlet to the Atlantic; a separate large disjunct range exists in all of south-eastern and coastal Brazil, including Paraguay, and parts of north-eastern Argentina. It is also found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.

The red-rumped cacique's natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, and heavily degraded former forest.

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.^[2] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature.^[3] 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.^[3] One of these was the red-rumped cacique. Linnaeus included a brief description, coined the binomial name Oriolus haemorrhous and cited Brisson's work.^[4] The specific name haemorrhous combines the Ancient Greek words haima "blood" and orrhos "rump".^[5] The red-rumped cacique is now the type species in the genus Cacicus that introduced by the French naturalist Bernard Germain de Lacépède in 1799.^[6][7]
