Corvids are among the most intelligent birds, with documented problem-solving, tool use, and theory of mind — making their welfare in both wild and captive contexts particularly significant.
Corvid intelligence makes their welfare especially ethically significant. Animals capable of planning, deception, and understanding others mental states have rich inner lives that are affected by captivity, persecution, and environmental stress. Corvids in Larsen traps experience prolonged confinement before killing; this causes significant welfare harm to highly cognitive animals. Urban corvids displaced from nest sites by development or harassment lose territory and resources that affect survival and wellbeing. The high intelligence of corvids should inform how we manage both their welfare and our conflicts with them.
