Ravens (Corvus corax) are recovering in parts of the UK and demonstrate exceptional cognitive abilities that raise important questions about their welfare needs and social complexity.
Raven welfare is shaped by their exceptional intelligence: a bored raven is a distressed raven. In captivity, ravens require complex social environments (pair housing minimum), varied cognitive enrichment including problem-solving tasks, and sufficient space for flight. Solitary housing is a major welfare concern for a species that forms lifelong social bonds. Wild raven welfare is primarily threatened by illegal persecution — poisoning and shooting on grouse moors is documented but underreported. Secondary poisoning from lead ammunition in game carcasses (as with red kites) is a welfare and conservation threat. Ravens' high intelligence means they remember and avoid areas where they have experienced persecution — land-use patterns therefore affect population distribution and individual welfare outcomes.
