Carrion crows are among the most intelligent birds on Earth. Their cognitive complexity raises important welfare questions about their treatment in legal and illegal lethal management contexts.
Carrion crow welfare is complicated by their legal status as a species manageable under general licences. Research on crow cognitive abilities — including demonstrated episodic-like memory, problem-solving rivalling great apes and face recognition — raises ethical questions about lethal management of such cognitively complex animals. Crows experience stress measurably in captures and confinement situations. Pain avoidance and fear responses are well-documented. The welfare case for proportionate rather than routine lethal management, and for ensuring humane killing methods when control is necessary, is supported by the evidence on crow sentience and intelligence. General licence killing of crows requires a specified purpose and genuine need — blanket culling without evidence is not consistent with either the licence conditions or the welfare evidence.
