Le Tangara doré (Tangara arthus) est un petit tangara que l'on trouve dans les contreforts des Andes et dans la zone subtropicale, du Venezuela à la Bolivie. Il est principalement jaune d'or brillant avec une tache noire isolée sur l'oreille, un dos strié et des ailes et une queue principalement noires. Quelques variations entre les populations, les oiseaux les plus septentrionaux présentant une bande mammaire et des flancs marron. Les sexes sont semblables ; les jeunes oiseaux sont d'un jaune plus terne. L'un des tangaras les plus communs en volées mixtes entre 900 et 2 200 m d'altitude, dans la forêt nuageuse, les lisières et les jardins.
Habitats et répartition
Golden Tanagers thrive in tropical and subtropical regions, primarily found in montane forests, forest edges, and secondary growth. They favor elevations ranging from 700 to 2400 meters. These birds typically inhabit humid environments, often residing in the canopy or mid-story layers of forests where they can find an abundance of fruits and insects to feed on. Geographically, Golden Tanagers are widely distributed in the Andean regions of South America. They can be found from western Venezuela, through Colombia and Ecuador, and into northern Peru. Their presence spans both the eastern and western slopes of the Andes, reflecting their adaptability to various montane forest environments within this range.
Comportements et reproduction
The Golden Tanager exhibits a complex and vibrant range of behaviors, especially during the breeding season. Mating pairs engage in elaborate courtship displays that include synchronized movements and vocalizations to strengthen their bond. These birds are generally monogamous, forming long-lasting pairs that collaboratively build nests and rear their young. Nests are typically constructed in concealed areas within dense foliage to protect against predators. Socially, Golden Tanagers often gather in mixed-species flocks outside of the breeding season, engaging in cooperative foraging which adds a layer of protection and enhances feeding efficiency. Unique reproductive strategies include a high level of parental investment, with both parents involved in feeding and caring for the chicks, significantly increasing offspring survival rates. The vibrant plumage of these birds, particularly the males, also plays a pivotal role in attracting mates and deterring rivals.

Statut de conservation et efforts
The Golden Tanager (Tangara arthus) is currently classified as "Least Concern" by the IUCN Red List, indicating that it is not at immediate risk of significant decline. The population trends are generally stable, although localized declines may occur due to habitat destruction. The primary threats to the Golden Tanager are deforestation and habitat fragmentation, particularly in the Amazon basin and Andean regions where agriculture and urban expansion reduce its natural habitat. Conservation efforts for the Golden Tanager focus on habitat preservation and restoration. Protected areas and national parks within its range play a crucial role in maintaining stable populations. Additionally, reforestation projects and sustainable land-use practices are being promoted to mitigate habitat loss. Conservation organizations are also working with local communities to raise awareness and engage in bird-friendly practices. Monitoring programs are in place to track population changes and ensure early detection of potential threats.
