Urban Wildlife Shows Convergent Behaviors Across Cities

Urban wildlife across the globe is exhibiting remarkably similar behaviors due to the influence of city environments. Animals such as monkeys in New Delhi, squirrels in New York, and white ibises in Sydney are becoming bolder, often interacting closely with humans and scavenging for food. This trend, known as behavioral homogenization, reflects a loss of behavioral diversity among species as cities select for traits like boldness, intelligence, and adaptability. Factors contributing to this phenomenon include consistent urban features like noise, light pollution, warmth, and human presence, which shape both the survival and reproductive strategies of animals. For instance, urban birds adjust their songs to overcome city noise, while raccoons and cockatoos learn to access human food sources, demonstrating cultural learning. These changes carry ecological consequences: reduced behavioral and genetic diversity limits species' resilience to environmental changes, complicates conservation e
