Why does the goose not move when it rains heavily?

Self-protection, feather insulation, limited vision.

1. Self-protection: The geese in the flock will form a defensive queue, led by a leading male goose, and the other geese will be arranged in turn. When it rains heavily to a certain extent, the geese will adopt a static strategy to protect the weak young geese in the flock from the rain.

2. Feather insulation: Goose's body is covered with dense feathers, which has good insulation performance. When it rains, geese will curl up, making their feathers stick together more closely, preventing rain from infiltrating into the skin and keeping their bodies warm.

3. Limited vision: In heavy rain, the vision will be blurred by the rain, which will limit the vision of the goose, so the goose will choose to stay still to avoid the risk of injury caused by impaired vision.
