Corvids - crows, ravens, rooks, jackdaws, and jays - are among the most cognitively sophisticated birds. Their intelligence raises welfare considerations both for wild corvids and for those kept in captivity.
Corvid welfare significance is substantial given their cognitive profile. Animals capable of planning, tool manufacture, and perspective-taking have correspondingly rich inner lives that can be enriched or impoverished by their circumstances. Wild corvids subjected to lethal control programs experience fear and death that carries more moral weight given this cognitive background. Captive corvids require extreme cognitive enrichment - puzzle feeders, novel objects, complex social environments - and are poorly served by bare cages. Their long-term memory and social awareness means they can form genuine relationships with human caregivers while also experiencing profound boredom in inadequate environments.
