So how do the small birds stay warm in the winter?

In the winter birds can grow twice as many feathers but they still have to shiver almost constantly to increase their body temperature in cold weather. This shivering process is called thermogenosis. The constant shivering produces heat five times that of their normal rate, helping them to maintain an amazingly high body temperature.

They also fluff up to trap air between their feathers and bodies to create a natural layer of insulation, and sleep with their bills under their wing feathers to breathe in warmer air. And of course they seek shelter out of the wind and cold. Some, such as the chickadees & titmice, huddle together in natural shelters like bushes. Also nesting boxes become roosting boxes in the winter. Or there are also roosting pockets.
