What common trait do birds in the genus Piranga often exhibit?
Answer
Pronounced sexual dimorphism
The genus *Piranga*, which encompasses the Western Tanager, Scarlet Tanager, and Summer Tanager, is frequently characterized by striking differences in appearance between the sexes, a phenomenon known as sexual dimorphism. During the breeding season, this manifests dramatically, with males displaying significantly brighter and more conspicuous coloration—such as the male Western Tanager's bright yellow body and black back—while the females generally possess a duller, olive-green or less vibrant plumage. This difference in visual signaling is a common feature linked to sexual selection pressures within this specific grouping of colorful, medium-sized American songbirds.
