I believe many bird-keeping friends know that birds change their feathers every year, but many people don't know why birds change their feathers. Today, I am going to tell you about this issue.

Why birds change feathers

The feathers of birds are very light and soft. Due to long-term contact with the external environment, they will always be consumed and worn. Therefore, replacement of feathers is a process that birds must go through to survive. In this way, we can fly better, survive and live better.
