Overview

• A study by mathematicians at NYU reveals new aerodynamic phenomena that help small groups of birds maintain formation while disrupting larger groups.
• Mechanized 'mock flocks' of 3D-printed wings in experiments mimic the aerodynamics of bird flight, showing how flock organization varies by group size.
• The findings introduce 'flonons,' wave-like disturbances that can destabilize flocks, akin to vibrational waves in material physics.
• Potential applications of these insights include more efficient propulsion systems and energy harvesting technologies.
• Diverse wing motions within flocks might prevent destabilizing resonances, suggesting strategies for stable, long-range formations.
