The accentors are a genus of birds in the family Prunellidae, which is endemic to the Old World. This small group of closely related passerines are all in the 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. These birds are not strongly migratory, but they will leave the coldest parts of their range in winter and make altitudinal movements.
Their typical habitat is mountainous regions in an area far above the tree-line, but below the snow-line. The Himalayan accentor can be found as high as 17,000 ft above sea level when breeding, however, most accentors breed in scrub vegetation at lower levels. Most species migrate downwards to spend the winter, with only some being hardy enough to remain. Accentors spend the majority of their time in the undergrowth and even when flushed, stay low to the ground until reaching cover.
