Answer: the most feathered bird in the world is the swan. It has 25216 feathers all over its body. Even if it lives in an environment of minus 34 degrees, it is no longer necessary. They enter the hair changing period every autumn, that is, from May to September. When they grow up, they change their hair twice a year, mainly in the head and neck.
Swan: the bird with the most feathers in the world. According to statistics, there are only less than 9000 feathers on a Luhua chicken, and more than double the number of swans. In fact, 80% of the more than 20000 feathers grow on the head and neck, and the combined weight of all feathers can reach 2-3 times the weight of bones. This is to ensure that swans can better resist the cold and fly, Even swans have leaped over Mount Everest to a height of 9000 kilometers. Swan's appearance features swan's neck is particularly slender, basically the same length as the body, and there is a mouth armor on the mouth. Adult swans are basically pure white feather color, and when they are young, they are relatively gray and black fluff. I believe everyone has heard the story of the 'ugly duckling'. Basically, when they are approaching adulthood, they will change the color and texture of their feathers by changing their hair. Not every kind of Swan has a crown on its head. Only the wart nosed Swan has a unique black wart process on its head. Life habits of swans swans like to live in open lakes and swamps. They mainly feed on aquatic plants such as reeds. They will start moving south every October, looking for warmer areas in groups to spend the cold winter. They will not gradually start flying to the North until March to April. Swans are very responsible for their spouses and offspring. They are basically monogamous. If one of them dies, the other will not live his life alone.
