Eurasian Blackbird

The common blackbird (Turdus merula) is a species of true thrush. It is also known as the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird. It breeds in Europe, western 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 former Asian subspecies are now widely treated as separate species. Depending on latitude, the common blackbird may be resident, partially migratory, or fully migratory.

The adult male of the common blackbird (Turdus merula merula, the nominate subspecies), which is found throughout most of Europe, is all black except for a yellow eye-ring and bill and has a rich, melodious song. The adult female and juvenile have mainly dark brown plumage. This species breeds in woods and gardens, constructing neat, cup-shaped nests bound together with mud. It is omnivorous, eating a wide range of insects, earthworms, berries, and fruits.

Both sexes are territorial on the breeding grounds and have distinctive threat displays. However, they are more gregarious during migration and in wintering areas. Pairs remain in their territory throughout the year if the climate is sufficiently temperate. This common and conspicuous species has given rise to a number of literary and cultural references, often related to its song.
