Attracting Songbirds in the Northeast: Winter

Who is actually here in January

Northeastern winter yards hold a fairly predictable cast: Black-capped Chickadee, Tufted Titmouse, White-breasted and Red-breasted Nuthatch, Downy and Hairy Woodpecker, Northern Cardinal, Blue Jay, House Finch, American Goldfinch in dull olive winter plumage, Dark-eyed Junco, White-throated Sparrow, Mourning Dove, and Carolina Wren at the southern end of the region.

In irruption years, boreal finches push south — Pine Siskin, Common Redpoll, Evening Grosbeak, and Purple Finch appear where they were absent the previous winter. These movements follow conifer seed crop failures in Canada, and a stocked nyjer and sunflower station is how you get a share of them.

Calories are the whole strategy

A chickadee can lose a substantial fraction of its body weight overnight in hard cold and must replace it during a short winter day. Everything you offer between December and February should be selected on fat content.

Black-oil sunflower and hulled sunflower chips lead. Suet is second and becomes essential below freezing — plain rendered suet, peanut-based cakes, or no-melt dough all work in cold weather. Peanuts in the shell draw jays, titmice, and woodpeckers. Nyjer in a fine-mesh or small-port feeder holds goldfinches, siskins, and redpolls. Skip generic mixes heavy in milo, wheat, and red millet; those get raked onto the ground and rot.

• Two sunflower feeders, spaced apart, to reduce crowding and disease transmission.
• One suet cage on a trunk or pole, shaded from afternoon sun.
• One nyjer feeder for finch flocks.
• A ground or low tray of white proso millet for juncos and white-throated sparrows.

Open water outperforms food

In a Northeastern January, liquid water is scarcer than calories. A heated bird bath, or a standard bath with a thermostatic de-icer rated for outdoor use, will often draw more species than any feeder in the yard — including birds that never touch seed, such as bluebirds and robins.

Keep the water shallow, no more than two inches at the deepest point, with a rough, grippable surface. Use a de-icer designed for bird baths rather than an aquarium heater, keep the cord protected and on a GFCI outlet, and never add glycerin, salt, or antifreeze of any kind to the water. These coat feathers and destroy insulation.

Cover and structure

Birds need thermal shelter as much as food. A dense conifer — eastern red cedar, spruce, hemlock — within twenty feet of the feeding station gives them somewhere to escape wind and hawks. If you have no conifer, stand your discarded Christmas tree upright near the feeders, staked or tied; it works well through the whole winter.

Leave seed heads standing. Coneflower, black-eyed Susan, goldenrod, aster, and native grasses feed finches and sparrows directly and hold overwintering insects that chickadees and woodpeckers hunt. Brush piles built from storm-fallen limbs shelter juncos, sparrows, and wrens through hard weather.

Roost boxes — deep, ventilation-free boxes with the entrance near the bottom and interior perches — let small birds share body heat overnight. They are a genuinely useful piece of winter hardware and, in a pinch, a nest box turned entrance-down works better than nothing.

Winter maintenance

Snow and freeze-thaw cycles turn seed into a solid block and feeders into disease vectors faster than in mild weather. Keep feeders covered with a weather dome, knock the snow off after each storm, and clean every two weeks with a 1:9 bleach solution — more often if you are seeing sick birds.

Once you start feeding in a Northeastern winter, keep going until spring. Birds do not become dependent on a single feeder, but they do build daily foraging routes around reliable sources, and a station that empties during a February ice storm costs them energy they cannot spare.
