Crows, ravens, and other corvids are among the most intelligent birds, and their welfare in urban environments is affected by human activities in complex ways.
Corvid welfare in urban environments intersects complex behavioral ecology with direct human-caused welfare harms. These are demonstrably intelligent animals capable of sophisticated cognitive tasks whose welfare deserves consideration beyond that typically afforded to common urban wildlife. Secondary rodenticide poisoning — which kills crows slowly through anticoagulant effects — is a significant and largely preventable welfare harm from careless pest control. Lead poisoning from hunting areas reaches urban corvids through scavenging. Nest destruction during breeding season causes acute welfare harm to dependent offspring. Addressing corvid welfare requires both specific interventions — rodenticide alternatives, lead ammunition bans, nest protection — and general recognition of these birds as cognitively sophisticated animals deserving active welfare consideration.
