The Eurasian blackbird (Turdus merula) is native to Europe, North Africa, and parts of Asia. It is widely distributed across the European continent, from the United Kingdom and Scandinavia in the north to the Mediterranean countries in the south, including Spain, Italy, and Greece. In North Africa, it can be found in countries such as Morocco, Algeria, and Tunisia. In Asia, its range extends to Iran and western parts of China, including areas such as the Himalayas.

The Eurasian blackbird typically inhabits a variety of environments ranging from woodlands, gardens, and parks to hedgerows and agricultural lands. It thrives in temperate regions, preferring areas with ample cover and access to food sources such as invertebrates and fruits. The species is highly adaptable and can also be found in urban and suburban areas where it seeks shelter and nesting sites in gardens and green spaces.

As an omnivorous bird, the Eurasian blackbird plays a critical role in seed dispersal and pest control. It feeds on a diverse diet, including insects, earthworms, seeds, and berries. Its ability to adapt to a wide range of habitats allows it to occupy various ecological niches across its distribution. The bird is primarily ground-dwelling, often seen foraging on the forest floor or in open grasslands, making it an important component of the ecosystem in controlling invertebrate populations.
