Acentor Común

Identificación

A robin-sized bird, the dunnock typically measures 13.5–14 cm (5.3–5.5 in) in length. It possesses a streaked back, somewhat resembling a small house sparrow. Like that species, the dunnock has a drab appearance which may have evolved to avoid predation. It is brownish underneath, and has a fine pointed bill. Adults have a grey head, and both sexes are similarly coloured.Unlike any similar sized small brown bird, dunnocks exhibit frequent wing flicking, especially when engaged in territorial disputes or when competing for mating rights. This gave rise to a common name of "shufflewing".<p>The main call of the dunnock is a shrill, persistent tseep along with a high trilling note, which betrays the bird's otherwise inconspicuous presence. The song is rapid, thin and tinkling, a sweet warble which can be confused with that of the Eurasian wren, but is shorter and weaker.

Taxonomía

The dunnock was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. He coined the binomial name of Motacilla modularis. The specific epithet is from the Latin modularis "modulating" or "singing". This species is now placed in the genus Prunella that was introduced by the French ornithologist Louis Pierre Vieillot in 1816.<p>The name "dunnock" comes from the English dun (dingy brown, dark-coloured) and the diminutive ock, and "accentor" is from post-classical Latin and means a person who sings with another. The genus name Prunella is from the German Braunelle, "dunnock", a diminutive of braun, "brown".<p>Eight subspecies are recognised:<p>Some taxonomists have recently suggested that dunnock might be better treated as three species, with P. m. mabbotti and P. m. obscura being elevated from subspecies status.

Distribución y hábitat

Dunnocks are native to large areas of Eurasia, inhabiting much of Europe including Lebanon, northern Iran, and the Caucasus. They are the only commonly found accentor in lowland areas; all the others inhabit upland areas. Dunnocks were successfully introduced into New Zealand during the 19th century, and are now widely distributed around the country and some offshore islands. Favoured habitats include woodlands, shrubs, gardens, and hedgerows where they typically feed on the ground, often seeking out detritivores as food.
