Streptopelia decaocto, commonly known as the Eurasian Collared-Dove, is native to the Indian Subcontinent, including countries like India, Sri Lanka, and Myanmar. Over time, it has expanded its range significantly beyond its original native regions.

The Eurasian Collared-Dove typically inhabits semi-open areas such as agricultural lands, urban areas, and suburban neighborhoods. It thrives in environments with moderate climate conditions where there is ample food supply and nesting sites.

The species has adapted to exploit areas where human activity has modified landscapes, such as farms and city parks, making it an opportunistic urban dweller. Its ability to consume a varied diet, including seeds and grains, supports its adaptation and survival in different habitats. Collared-Doves are also known for their adaptability to a wide range of conditions, which has facilitated their widespread colonization outside their native range.
