The golden-naped tanager (Chalcothraupis ruficervix) is a
species of bird in the tanager family
Thraupidae. It is found in South America from Colombia to Bolivia. Its natural
habitats are subtropical or tropical moist
montane forests and heavily degraded former forest.
Taxonomy
The golden-naped tanager was illustrated by the French naturalists
Florent Prévost and
Marc Athanase Parfait Oeillet Des Murs in 1842. They coined the
binomial nameTanagra ruficervix.[2] The
type locality is
Bogotá in Colombia.[3] The specific epithet combines the Latin rufus meaning "red" and cervix meaning "nape".[4] A
molecular phylogenetic study published in 2014 found that Tangara was
polyphyletic and in the rearrangement to create
monophyletic genera, the golden-naped tanager was moved to the resurrected genus Chalcothraupis.[5] The genus had originally been introduced by the French naturalist
Charles Lucien Bonaparte in 1851 with the golden-naped tanager as the
type species.[6] The genus name combines the
Ancient Greekkhalkos meaning "bronze" and thraupis, an unidentified small bird.[7]

Description
Golden-naped tanagers have plumage similar to those of the
metallic-green tanager, the
swallow tanager and the
blue-and-black tanager[9] as adults of all three species are primarily blue with black facial masking, however, the golden-naped tanager is the only primarily blue tanager with a golden or reddish crown patch or nape.[10] Females have a similar pattern to males, but have duller colors and a narrower nape patch. Juveniles of both genders have a primarily dull blue-gray coloration with a lighter breast and belly, and lack the distinctive golden nape.
