The
accentors are in the only
bird family,
Prunellidae, which is
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.
