You aren't the only one looking to stay warm and safe during winter storms. Consider a roosting box to provide a haven for local birds.
Different from nesting boxes or houses, roosting boxes have entrances at the bottom, to keep warm air trapped inside the box. They typically come with perch pegs or ladders to allow a crowd of birds to huddle together to escape bad weather and benefit from each other's body heat. Place the house where it will receive the most sunlight to maximize warmth.

In spring, the box can be converted into a nesting box by removing the ladder and turning the front panel so the entry hole is at the top. Crafted of Eastern white pine with a slate predator guard around the entrance, it measures 7-by-9-by-13 inches; $59.95 at Duncraft.
