Fireworks on New Year's Eve disrupt bird flight patterns, study finds

Research using weather radars and bird counts reveals that millions of birds are affected by the mass use of fireworks on New Year's Eve, with the effects felt up to 10 km away. The sudden noise and light cause birds to take flight, resulting in a significant loss of energy. Larger birds, such as geese, ducks, and gulls, fly at remarkable altitudes for hours after the fireworks, increasing the risk of accidents and exposure to bad weather. The study suggests implementing fireworks-free zones in areas where large birds live and promoting light shows without sound as an alternative.
