Le Tangara à anneaux d'or (Bangsia aureocincta) est un magnifique tangara limité aux Andes occidentales de la Colombie. C'est l'un des oiseaux endémiques les plus recherchés du pays en raison de son plumage unique et de sa rareté. Les femelles et les jeunes oiseaux sont plus ternes que les mâles adultes. Il habite les forêts nuageuses humides et se joint parfois à des groupes d'espèces mixtes. Souvent perché sur une branche exposée, il émet à plusieurs reprises des notes aiguës qui s'élèvent puis retombent.
Habitats et répartition
Inhabiting the humid montane forests of the western Andes in Colombia, the Gold-ringed Tanager thrives at elevations between 1,300 and 2,200 meters. This bird typically favors subtropical or tropical moist lowland forests, as well as subtropical or tropical moist montane forests, where dense vegetation provides ample food resources and shelter. Its geographical range is quite restricted, mostly confined to the Chocó biogeographic region, which is renowned for its high levels of biodiversity and endemism. Due to such a limited distribution, the Gold-ringed Tanager's populations are concentrated in areas that are unfortunately subject to deforestation and habitat loss, making conservation efforts vital for its continued existence.
Comportements et reproduction
The Gold-ringed Tanager exhibits a monogamous mating system, where pairs form long-term bonds and share responsibilities in nesting and rearing their offspring. These birds often construct their nests in dense shrubbery or trees, utilizing moss, leaves, and other plant materials to create a well-camouflaged home. The female typically handles incubation duties, while the male actively participates in foraging and feeding both the incubating female and the hatchlings. Gold-ringed Tanagers are known for their cooperative breeding behavior within a defined social structure. While primary reproductive duties lie with the breeding pair, non-breeding individuals, often previous offspring, may assist in defending the territory and feeding the young. This cooperative approach enhances the survival rates of the offspring, ensuring that the population remains robust despite the challenging environmental conditions of their native habitats.

Statut de conservation et efforts
The Gold-ringed Tanager (Bangsia aureocincta) is currently classified as Endangered on the IUCN Red List due to its restricted range and declining population, primarily driven by habitat loss. The species is found predominantly in Colombia's western Andes, where deforestation for agriculture, logging, and human settlement continues to fragment its cloud forest habitat. Population trends indicate a continuing decline, although exact numbers remain unclear due to difficulties in surveying the species in its dense and rugged habitat. Conservation efforts for the Gold-ringed Tanager focus on habitat protection and restoration. Key initiatives include establishing and expanding protected areas and reserves, such as the Montes de Tatamá National Park, which overlap with the bird’s habitat. Additionally, local NGOs and international partnerships work to promote sustainable land-use practices and reforestation projects. Education and community engagement are also essential components, aiming to raise awareness about the tanager’s plight and reduce human impact on its environment.
