The Common Blackbird, Turdus merula, is a species of true thrush. It is also called Eurasian Blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply Blackbird (in areas where it is the only blackbird-like species). It breeds in Europe, Asia, and North Africa, and has been introduced to Australia and New Zealand. It has a number of subspecies across its large range; a few of the Asian subspecies are sometimes considered to be full species. Depending on latitude, the Common Blackbird may be resident, partially migratory or fully migratory.
