They puff up to say warm. Here’s a quote from Bird Watchers Digest: “How do birds stay warm in the winter?
Birds have a number of ways to beat the cold, but none so important as their feathers. You may have noticed how on a very cold day the birds at your feeder seem rounder and more puffed-up than usual. This is a way of keeping warm by raising the feathers to create pockets of warm air and enhance insulation. In addition, may species change their plumage, molting into a fresh thick set of feathers prior to the colder months.
Especially helpful are the very fluffy and soft body feathers known as down. These feathers provide super insulation, much like the goose down we use in coats and comforters.”
PUFFY
Would have made a good title 🙂
Good capture. Are they always puffy, or is it because they are cold?
