Dunnock 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. Favourite habitats include woodlands, shrubs, gardens, and hedgerows where they typically feed on the ground often seeking out detritivores as food.

Bird colony (Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonies on the ground. Herons, egrets, storks, and other large waterfowl also nest communally in what are called heronries. Colony nesting may be an evolutionary response to a shortage of safe nesting sites and abundance or unpredictable food sources which are far away from the nest sites. Colony-nesting birds
