Corvid intelligence rivals that of great apes, with profound implications for how we understand and treat these common but often persecuted birds.
The demonstrated cognitive capacities of corvids — including future planning, theory of mind, and tool manufacture — place them in a cognitive tier alongside the great apes. Yet corvids are frequently killed as agricultural pests, excluded from wildlife protection regulations, and persecuted with traps. The gap between what we know about corvid intelligence and how we treat them represents one of the clearest examples of how cognitive evidence has not yet translated into welfare consideration.
