Cozy Winter Housing for Birds

If you think birdhouses are just for nesting, you're wrong. On cold, winter nights, songbirds use tree cavities and human-provided nest boxes as shelter.

You might be surprised at how many of your bird houses are used as nighttime roosts in winter. Telltale clues are there in the form of droppings, feathers, and bits of food.

If you live in a region with cold winter weather, you can make your nest boxes cozier with a few winterizing tricks. Start by cleaning out the box if it has messy old nesting material in it. Fashion a new nest cup of clean, dried grasses and place it in the box.

This is a good time to check the water resistance of your nest boxes. If the sides or top are weathered or cracked they may absorb rather than shed water. If the wood is too far gone, it's time to replace the house.

Otherwise, a coating of all-weather wood stain or light-colored latex paint will help keep the winter dampness out. Stain or paint the outside surfaces only and try to do it when birds are not likely to use the house.

This is also a good time to check the hardware on your boxes and poles. Wood can shrink as it weathers, and screws and nails can work loose. Are the access doors closing tightly? Is the box securely attached to the pole? Is the baffle still hanging properly?

The final bit of winterizing involves plugging the boxes' vent holes. These holes are vital in summer to keep the nestlings from getting too hot. In winter the holes are just drafty. We plug the vent holes using moldable clay weather stripping. Stuff the weather stripping snugly into the vent holes from the outside. This will help keep the body heat of roosting birds from escaping, and it will keep rain and snow from getting into the box. Cozy winter housing is a small gift you can give to your birds as the cold weather sets in.

  • I understand that the ducks' blood vessel arrangement in their feet is to provide the benefits of the counter-current heat exchanger mechanism; returning cold venous blood from the feet is warmed by the descending warm arterial blood, preventing excess heat loss by the feet and avoiding cold blood from chilling the body. This means that the feet are cold, not warm.

  • I have the same situation. The feeder is attached to the middle of a large picture window that goes ceiling to floor w/ no ledge or sill for animals to climb or balance. Yet every morning all the sunflower seeds have been cracked open and hulls left. Any ideas what it is?

  • I have a bird feeder that sticks to my window and I've been hearing noises against the window at night right now its going on. But whatever it is it is aware of me. And when I get to window it leaves.I can't imagine a squirrel or mouse or possom being able to get at it. ...So as I was reading this article im to assume no bird eats at night. Or no birds will eat at night. Why is that? Then im also thinking of a sinereo that could a lost confused bird eat at night. This eating thing is watching meI turn out the light go there noise dissappears..Thank you.
