Birds
Tanager
Thraupidae · also called tanagers
Tanagers are one of the largest songbird families found only in the Americas, and within that single family sits some of the most electrically colourful birds in the world alongside plenty of quiet, understated relatives most people would never guess belong to the same group at all.
Overview
Tanagers, family Thraupidae, are a large, diverse songbird family found only in the Americas, with the greatest species richness concentrated in the tropical forests of the Andes and Amazon basin. They eat a mix of fruit, nectar, and invertebrates, playing an important role in seed dispersal and pollination.
A family redrawn by genetics
Colouration across the family ranges from some of the most vividly saturated plumage in the bird world to comparatively plain relatives in the very same group. Modern genetic research has significantly reshuffled which species actually belong in Thraupidae, moving some out and adding others previously classified elsewhere.
Status
Least Concern collectively, though decreasing for a meaningful number of range-restricted Andean cloud-forest species vulnerable to ongoing deforestation.
Tanager: common questions
Are all tanagers brightly coloured?
No, while some of the most well-known tanager species display extremely vivid, saturated colours that have made the family famous among birdwatchers, a substantial number of other species within the same broad family are comparatively plain, subdued, or streaky in appearance. The tanager family's enormous size and diversity means it includes birds across a very wide range of colouration, from some of the most spectacular plumage in the Americas to considerably more understated relatives that receive far less attention.
Why has scientific understanding of which birds count as tanagers changed so much?
Modern genetic analysis has revealed that traditional classification based mainly on physical appearance and behaviour did not always accurately reflect true evolutionary relationships, leading researchers to reclassify certain species previously grouped with tanagers into other families, while also identifying other species, not traditionally considered tanagers, as genuinely belonging within the family based on genetic evidence. This kind of significant taxonomic revision driven by genetic data has affected numerous bird families in recent decades, but the scale of change within Thraupidae has been particularly notable given how large and diverse the family already was.
Where are most tanager species found?
While a number of tanager species breed in temperate parts of North America during the summer, the overwhelming majority of the family's total species diversity is concentrated in the tropical forests of Central and South America, particularly in the Andes mountains and the Amazon basin, regions renowned generally for exceptionally high bird diversity. This concentration reflects the tanager family's origins and ongoing diversification centred specifically in Neotropical forest habitats rather than more temperate regions.
Why are tanagers ecologically important beyond just being colourful?
Many tanager species feed heavily on fruit and, in some cases, nectar, and in doing so they play a significant role in dispersing plant seeds across the forests they inhabit as they move between feeding sites, while nectar-feeding species can also contribute to pollination of certain plants. This makes tanagers ecologically important contributors to forest regeneration and plant reproduction, a functional role that exists independently of and receives considerably less popular attention than their often striking, colourful appearance.
