Hepatic Tanager (Piranga flava) Science Article 1
abstract
The geographic range of Piranga hepatica hepatica, as now understood, extends from Arizona to southern Mexico. Examination of a series of 115 specimens of this species in the United States National Museum, including the Biological Survey collection, reveals the existence of an additional and undescribed subspecies from the southwestern United States.
