accentor

n. Eurasian and African songbird that resemble the sparrow

The accentors are in the only bird family, Prunellidae, which is completely endemic to the Palearctic. This small group of closely related passerines are all in a single genus Prunella. All but the Dunnock and the Japanese Accentor are inhabitants of the mountainous regions of Europe and Asia; these two also occur in lowland areas, as does the Siberian Accentor in the far north of Siberia. This genus is not strongly migratory, but they will leave the coldest parts of their range in winter, and make altitudinal movements.
