The dunnock (Prunella modularis) is a small passerine, or perching bird, found throughout temperate Europe and into Asian Russia. Dunnocks have also been successfully introduced into New Zealand. It is by far the most widespread member of the accentor family; most other accentors are limited to mountain habitats. Other common names of the dunnock include: hedge accentor, hedge sparrow or hedge warbler.
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.
Dunnocks exhibit a variety of mating systems, with females often engaging in polyandry. Males attempt to ensure paternity by pecking at the female's cloaca to stimulate the ejection of rival sperm. The species is known for its quick copulation, which can occur more than 100 times a day. Parental care is generally proportional to mating success, with both males and females commonly seen provisioning at a single nest.
The dunnock's streaked back and drab coloration may lead to confusion with the house sparrow, but its distinctive behavior and calls can aid in proper identification.
Dunnocks primarily feed on the ground, often targeting detritivores as a food source.
