The Dunnock, Prunella modularis, is a small passerine bird found throughout temperate Europe and into Asia. It is by far the most widespread member of the accentor family, which otherwise consists of mountain species. It is sometimes called the Hedge Accentor, Hedge Sparrow or Hedge Warbler. It is a resident in the milder west and south of its range, but as an insectivore, must migrate south from the colder parts of its range. It is a bird of woodland, shrub and gardens.

All shot through a double-glazed window, that's why they seem a little blurry.
