Question

Birds puff up their feathers winters...



why?? can someone tell me?​

Answer 1

Answer: And just like the coats people wear, birds tend to get puffier in winter. “A bird's body heat warms the air between its feathers,” Marra explains. “So birds fluff up in the cold to trap as much air in their feathers as possible. The more trapped air, the warmer the bird.”
