According to Baidu Library, seagull's mouth is thin and long, and there are two small black spots at the end of yellow mouth. It has a pair of black eyes on both sides of the white, like a pair of black pearls embedded in the west, which is particularly eye-catching. Its abdomen is snow-white, and a pair of gray wings swing rhythmically with a pair of feet like duck's feet, and it clings to the tail wing when flying. The fan-like tail is very neat and beautiful, as if it had been trimmed with scissors.
