Cold Weather Survival For Birds

Question: How do birds survive in cold weather?

Answer From George Harrison at Birds and Blooms:

Birds that reside in the North in winter are well equipped to survive the cold. Their winter plumages contain twice the number of feathers as their summer garbs. Plus, they can fluff up their feathers to further insulate their bodies and then shiver.

At night, birds conserve energy and heat by putting themselves into a state of hypothermia, which slows down their breathing, heartbeat and metabolism. Get more answers here.
