Various or variegated, fitting for its sharp, contrasting black, white, and red markings
The specific epithet used in binomial nomenclature carries essential descriptive meaning derived from Latin or Greek roots. In the case of *Sphyrapicus varius*, the name *varius* translates directly to 'various' or 'variegated.'
