The Scarlet-rumped Cacique ("Cacicus uropygialis") is a passerine bird species in the New World family Icteridae. It breeds from eastern Honduras to Panama and in the Pacific lowlands of South America from western Colombia south to Ecuador, and in the lower reaches of the northern Andes. There are several subspecies, some of which have been proposed for elevation to full species status.

As a whole, "C. uropygialis" it is usually called the Scarlet-rumped Cacique. However, it is often split into two species, in which case this name is limited to "Cacicus (uropygialis) microrhynchus" (with subspecies "pacificus"), while the nominate subspecies, "C. u. uropygialis", is referred to as the Subtropical Cacique.Jaramillo & Burke (1999)] . The "true" Scarlet-rumped Cacique - then "Cacicus microrhynchus" - may also be split further; the Pacific populations have been proposed as the Pacific Cacique ("Cacicus pacificus").Salaman "et al." (2002)] The AOU considers it likely that at least two species are involved, but points out that no dedicated analsyis of the data at hand has been published. It therefore does not formally recognize the split at present. [SACC (2003)]


The Scarlet-rumped Cacique has sexual dimorphism like many Icteridae, though it mainly concerns size in this species. Males are 23 cm (9 in) long and weigh 68 g (2.4 oz), while the female is 20 cm (8 in) long and weighs 53 g (1.9 oz); they follow Bergmann's Rule, with the Subtropical Caciques of the cooler uplands being larger. This cacique is a slim long-winged bird, with a relatively short tail, blue eyes, and a pale yellow pointed bill. It has mainly black plumage, apart from a scarlet patch on the lower back and upper rump. The female is smaller and a duller black than the male, and the juvenile bird has a brownish tone to the plumage and a brownish-orange rump.

The song of these birds is a pleasant "wheee-whee-whee-whee-wheet", but the Pacific Cacique has a descending melancholy "wheeo-wheeo-wheeo-wheeo". The calls birds give to members differ between the three groups: those of the Subtropical Cacique sound rather untypical for icterids and more like the chatter of an excited Great Thrush ("Turdus fuscater"). The Scarlet-rumped Cacique in the narrowest sense has a burry "pleeo"; the Pacific Cacique has a sweeter "keeo" or a "shree".

Ecology and distribution

The Scarlet-rumped and Pacific Caciques are birds associated with humid lowland primary forest or old secondary forest at up to 1000 m (3,300 ft) ASL. The Scarlet-rumped Cacique is found from Honduras, through Nicaragua and Costa Rica, to Panama (except Darién), while the Pacific Cacique is found from eastern Panama (Darién), through western Colombia, to western Ecuador.

Subtropical Caciques occur at higher altitudes; they have been recorded as high as 2,450 m (8,000 ft) ASL and are found along the eastern slopes of the Andes at altitudes of 1000-2300 m (3300-7500 ft) in submontane or cloud forest, ranging from Venezuela, through Colombia and Ecuador, to Peru, with an isolated population in the Serranía del Perijá. Their habitat has a lower canopy than that of their lowland relatives, dominated by trees of little more than 15-20 (50-65 ft) height, for example oaks ("Quercus"). Epiphytes, hemiepiphytes like "Coussapoa" (Urticaceae), and a usually dense understory with tree ferns, Ericaceae, etc. are also typical habitat features.

These caciques forage through the canopy in small flocks. It feeds on large insects, spiders and small vertebrates, but will also take some fruit. It often forms mixed-species feeding flock with similarly robust and rowdy songbirds, such as other icterids [E.g. Mountain Cacique ("Cacicus leucoramphus") or Russet-backed Oropendola ("Psarocolius angustifrons"), observed for Subtropical Caciques: Salaman "et al." (2002).] , Black-faced Grosbeaks ("Caryothraustes poliogaster"), or American jays [E.g. Green Jay ("Cyanocorax yncas") or White-collared Jay ("Cyanolyca viridicyana"), observed for Neotropical Caciques: Salaman "et al." (2002).] . Such noisy flocks may also attract trogons or flycatchers.

Unlike some other caciques they are not usually colonial breeders; like them they have a bag-shaped nest. It is built about c. 3.5-30 m (10-100 ft) above ground, in a tree which usually also contains an active wasp nest. The bird's nest is 36-64 cm (14-25 in) long, widens at the base, and is suspended from the end of a branch. The normal clutch is two dark-blotched white eggs. The male will assist in feeding the young, but does not incubate.

The IUCN conservation status of Least Concern applies for the taxon in the broad sense. [BLI (2004)] Both the Scarlet-rumped (in the narrower sense) and the Pacific Cacque are widespread and locally common. The Subtropical Cacique is generally uncommon to rare, but due to its extensive range unlikely to be seriously threatened.
