House Crow
The House Crow (*Corvus splendens*) is a highly adaptable and intelligent bird species native to the Indian subcontinent but has spread to many other parts of Asia and beyond. Known for its opportunistic nature and close association with human settlements, it plays a significant ecological role as a scavenger, helping to control waste and insect populations. However, in some introduced regions, it is considered an invasive species due to its negative impact on native wildlife. Culturally, the House Crow is often seen as a symbol of resourcefulness and adaptability, but also sometimes viewed as a pest.
