The scarlet tanager (Piranga olivacea) is a distinctive songbird of eastern North America and a long-distance migrant to the tropics. Males in breeding season are strikingly red with contrasting dark wings and tail, while females and immatures are yellowish-olive. The species belongs to the genus Piranga and has been the subject of taxonomic revision in recent decades.
Identification and characteristics
The male scarlet tanager in spring and summer shows vivid scarlet plumage across the body paired with black wings and tail, a combination that makes it conspicuous in the canopy. Outside the breeding season males become duller and more olive-colored. Females and young birds are generally yellow-green above and paler below, which helps them remain inconspicuous among leaves. Its voice is often described as a somewhat hoarse or burry song, and the calls include short, sharp chips.
Range, habitat and migration
Scarlet tanagers breed in mature deciduous and mixed woodlands, preferring large tracts of canopy where they forage and nest. They are found across eastern North America during the breeding season and undertake long migrations to spend the winter in parts of Central and northern South America. This biogeographic pattern connects breeding and wintering areas across the Americas and makes them dependent on habitat quality in multiple countries.
Nesting and reproduction
Nests are cup-shaped and typically placed in the tree canopy where foliage provides concealment. Many pairs choose oaks and other tall deciduous trees for nest sites; nests may be located anywhere from lower branches to the upper canopy, in some cases rising several meters above the ground and occasionally much higher. The female builds the nest from twigs, bark strips, grasses and other plant fibers; the cup form helps keep eggs and nestlings secure in a leafy, arboreal setting. For more on typical nest placement and preferred trees see resources about nesting birds in oak trees.
Diet and behavior
Scarlet tanagers are primarily insectivores during the breeding season, gleaning insects from foliage or catching them on the wing. They also consume fruit and berries, especially outside the breeding season and on migration. In forest canopies they can be somewhat secretive despite the male's bright color, often moving among leaves rather than perching on exposed branches. Their foraging habits and seasonal dietary shift illustrate their ecological role as both predator of arthropods and seed disperser.
Conservation and notable facts
Although not currently listed as globally threatened, scarlet tanagers have experienced declines in parts of their breeding range due to habitat fragmentation, loss of large mature forest tracts, and threats encountered during migration and on wintering grounds. Conservation efforts that protect contiguous woodland, maintain forest quality, and mitigate hazards along migratory routes benefit this species. The scarlet tanager is sometimes confused with related Piranga species such as the summer tanager, but adult male plumage and wing coloration help distinguish them.
