Here are some tips to keep in mind.
High-calorie suet is vital to keeping birds warm in winter
Hang as many suet feeders as you have room for. I like to decorate the strong-limbed shrubs in my front yard with fist-size chunks of suet wrapped in a red plastic onion-bag mesh. If a bird or raccoon rips through the netting, it's no great loss; I just add another.

Keep a supply of suet in the freezer
Keeping a supply in your freezer ensures that you don't get caught short. I chop it into manageable chunks before storing so I can take just what I need and not have to wrestle a big frozen hunk.

Lay in a stock of seed in case of emergency
You don't want to get caught short when you need it the most. I keep a 50-pound sack of sunflower seed in the trunk of my car in winter. It serves two purposes: extra traction when the roads are slick, and extra bird food should a blizzard descend.

Run an immersible heater to the birdbath
Or try a solar birdbath that uses the sun's heat to keep water from freezing. At the very least, you can put out a shallow pan or clay saucer of warm water once a day. Take it into the house when the water begins to freeze.
Treat birds to home cooking
Make muffins, bread, and other snacks with nutritious additions like sunflower seeds and nuts.
