Tanagra dalla cresta di fiamma

Identificazione

The flame-crested tanager grows to a length of about 15 cm (6 in) and a weight of around 20 g (0.7 oz). The male has a black head, small orangeish-red bib and a moderate-sized orangish crest. The upper parts are slatey-black with a golden-buff rump, and the upper wing-coverts bear a large patch of white. The underparts are dark brownish-black. The female is similar in appearance to the white-winged shrike-tanager (Lanio versicolor) but is more brown above with buff-ochre rather than yellowish-ochre underparts.

Tassonomia

In 1760 the French zoologist Mathurin Jacques Brisson included a description of the flame-crested tanager in the supplement to his Ornithologie based on a specimen collected in Cayenne, French Guiana. He used the French name Le tangara noir hupé de Cayenne and the Latin name Tangara cayanensis nigra cristata. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised 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 in his Ornithologie. One of these was the flame-crested tanager. Linnaeus included a terse description, coined the binomial name Tanagra cristata and cited Brisson's work. The flame-crested tanager was formerly placed in the genus Tachyphonus. A molecular phylogenetic study published in 2014 found that Tachyphonus was polyphyletic. In the subsequent reorganization the genus Loriotus was resurrected for the flame-crested tanager and two other species. The genus had been introduced in 1821 by the Polish zoologist Feliks Paweł Jarocki. The genus name is derived from the French word loriot that is used for the Old World orioles. The specific name cristata is Latin for "plumed" or "crested".<p>Ten subspecies are recognised.

Areale e habitat

This species is native to lowland forest in the northern half of South America. There are two disjunct populations, the larger covering most of the Amazon Basin in Brazil, southern parts of Venezuela, Guyana, Suriname and French Guiana, and eastern parts of Colombia, Ecuador, Peru and Bolivia. The separate part of the range is occupied by the subspecies L. c. brunneus and covers a coastal strip of Brazil from Recife to Curitiba.
