Birds that give beauty and inspiration to humanity | Photography Enthusiast

Birds have given mankind many invaluable inspirations: seeing birds flying in the sky, people thought of a machine that could take us to fly in the sky: airplanes; the firmness and steadiness of a mountain eagle just before it lands, makes people feel that they can also fly down from the sky and land safely; dragonflies in flight inspired mankind to create helicopters; the skillful and silent flight of owls has improved the performance of airplanes.
