Description

The Black Redstart is 13–14.5 cm in length and 12–20 g in weight, similar to the Common Redstart

. The adult male is overall dark grey to black on the upperparts and with a black breast; the lower rump and tail are orange-red, with the two central tail feathers dark red-brown. The belly and undertail are either blackish-grey (western subspecies; see Systematics, below) or orange-red (eastern subspecies); the wings are blackish-grey with pale fringes on the secondaries forming a whitish panel (western subspecies) or all blackish (eastern subspecies). The female is grey (western subspecies) to grey-brown (eastern subspecies) overall except for the orange-red lower rump and tail, greyer than the Common Redstart; at any age the grey axillaries and underwing coverts are also distinctive (in the Common Redstart these are buff to orange-red). One-year old males are similar to females but blacker; the whitish wing panel of the western subspecies does not develop until the second year.

 to winter in southern and western Europe and Asia, and north Africa. It nests in crevices or holes in buildings.

In Britain it is most common in as a passage and winter visitor, with only 20–50 pairs breeding. On passage it is fairly common on the east and south coasts, and in winter on the coasts of Wales and western and southern England, with a few also at inland sites. Migrant Black Redstarts arrive in Britain in October or November and either move on or remain to winter, returning eastward in March or April. They also winter on the south and east coasts of Ireland.
