Watch thousands of birds fly in tight formation—a mesmerizing behavior known as a starling murmuration. | National Geographic

A mesmerising Starling murmuration. A murmuration is a breathtaking natural phenomenon where large flocks, primarily of starlings, move together in mesmerizing, synchronized aerial patterns, forming dynamic shapes and swirls in the sky, usually at dusk for safety and warmth before roosting, a display so complex it seems like a single, fluid organism. #murmuration #birds #wildlife #nature #birdlife #birdlovers #birdwatching | The Robin Whisperer
