They are merely puffed up, thickening the insulation around their bodies. At night, they reduce heat loss by seeking shelter in tree holes or other crevices, and by reducing their body temperature—the smaller the difference in temperature between the bird and its environment, the lower the rate of heat loss.
Can sparrows die of cold?
Yes, birds can freeze to death if they’re injured or not used to chilly winters. Besides, if a bird has any unexpected health issues, it can be helpless and die of freezing weather. So, the healthier birds adapt to different temperatures, particularly harsh winter weather.
How do sparrows stay warm in winter?
All birds stay warm by trapping pockets of air around their bodies. The secret to maintaining these layers of air lies in having clean, dry and flexible feathers.

Why do some birds stay for the winter?
Some birds stay for the winter because they have developed adaptations to deal with the cold winter. These adaptations include changing their diet, insulative feathers, high metabolic rates, shivering, fluffing of feathers, cuddling, countercurrent heat exchange, and tucking in of their extremities.
Why do birds puff up their feathers 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. One way birds keep their legs and feet warm is to stand on one leg, while the other is tucked up warmly in its feathers.
Why do birds not fly at night?
