Crows and corvids display extraordinary cognitive abilities including tool use, causal reasoning, and social learning. Understanding their intelligence changes how we should think about their welfare in urban environments.
The cognitive complexity of corvids raises their moral status considerably. Urban crows face welfare challenges including secondary poisoning from rodenticides, nest removal, and deliberate persecution. Given their demonstrated capacity for learning, social bonds, and potentially long-term memory of negative experiences, lethal control of corvids is ethically problematic when non-lethal alternatives exist.
