The genus Prunella was introduced by the French ornithologist Louis Vieillot in 1816 with the dunnock as the type species. Although the genus is usually used for all the accentors, the alpine accentor and Altai accentor are sometimes separated into the genus Laiscopus. Harrison used the group name dunnock for all of the species, not just Prunella modularis ; this usage is based on the oldest known name for any of the species. Accentor derives from the old scientific name for the Alpine accentor. It comes from Late Latin, meaning "sing with another". The genus namePrunella is from the German Braunelle, "dunnock", a diminutive of braun, "brown".
Description
These are small, fairly drab species superficially similar, but unrelated to, sparrows; they are generally regarded as being related to the thrushes or the warblers. They are 14 to 18 centimetres in length, and weigh between 25 and 35 grams. However, accentors have thin sharp bills, reflecting their diet of ground-dwelling insects in summer, augmented with seeds and berries in winter. They may also swallow grit and sand to help their stomach break up these seeds. Most of the species live together in flocks. The dunnock is an exception since it prefers to be solitary except when feeding. The dunnock also earned a nickname of "shuffle-wing" since it most strongly displays the characteristic wing flicks used during courtship and other displays. Accentors may have two to three broods a year. Courtship consists of a great deal of song from the males, which may include short lark-like song flights to attract a mate. In most species, the male and femaleshare in the nest making, with the dunnocks again being an exception – their males have no part in nest building or incubation. They build neat cup nests and lay about 4 unspotted green or blue eggs. The eggs are incubated for around 12 days. The young are fed by both parents and take an additional 12 days or so to fledge.
Habitat
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.
