How to attract cowbirds to your yard
Brown-headed Cowbirds respond to four things: the right food, the right plants, water and safe nesting cover. Here is what each means for this particular bird, drawn from its range across 58 states and provinces.
First: is it in your area, and when?
You can only attract a bird that passes through or lives near you, so start with timing. The Brown-headed Cowbird is a year-round resident in 56 states and provinces, including Alabama, Alberta, Arizona, Arkansas, British Columbia, California and 50 more — there, a yard can host it in every season. It arrives only to breed in 2, such as Northwest Territories, Yukon, so set up before spring arrival.
Plant what cowbirds use
These native plants are tied to the Brown-headed Cowbird in our regional plant lists (Audubon Native Plants and state sources). The count shows how many states or provinces list the plant for this bird — higher means it works across more of the range. Pick the ones native where you live.
| Plant | Type | States | Why it helps |
|---|---|---|---|
| Black-eyed Susan Rudbeckia hirta | Perennial | 55 | Prolific seed heads for finches and sparrows. |
| Little bluestem Schizachyrium scoparium | Perennial | 54 | Native bunchgrass; winter seed and ground cover for sparrows and juncos. |
| Tall goldenrod Solidago altissima | Perennial | 54 | Insect-rich in fall and seed in winter. |
| Wild bergamot Monarda fistulosa | Perennial | 54 | Tubular flowers for hummingbirds and seed heads for finches. |
| New England aster Symphyotrichum novae-angliae | Perennial | 38 | Late nectar for insects and fall seed for sparrows. |
| Common sunflower Helianthus annuus | Perennial | 29 | Annual native sunflower — the original feeder seed. |
| Sugar maple Acer saccharum | Tree | 29 | Hosts hundreds of caterpillar species; spring flowers draw early insects. |
| Paper birch Betula papyrifera | Tree | 28 | Catkin seed feeds redpolls and siskins all winter. |
| Purple coneflower Echinacea purpurea | Perennial | 27 | Leave seed heads up through winter for goldfinches. |
| Red maple Acer rubrum | Tree | 27 | Among the first spring bloomers; early insects for returning migrants. |
Your list covers 2 plant layers (perennial, tree). Layering matters: add structure around these — a shrub layer under the trees gives cowbirds a safe approach. Leave seed heads and fruit standing into winter instead of cutting back in fall.
Offer the food it actually eats
Seeds and insects taken on the ground.
- Warm months
- Grasshoppers, beetles and grass seeds
- Cold months
- Grain and feeder seed
- At feeders
- Millet, Cracked corn, Mixed seed
Feeder style matters as much as food: low ground tray under cover is the first choice for this bird. A brood parasite — it lays eggs in other birds' nests. Feeding less millet and avoiding platform scatter reduces cowbird crowds. Feeder guide →
Give it a place to nest
Natural site: Builds no nest — lays eggs in the nests of other species.
It does not use nest boxes, so the way to host a nest is cover: keep dense native shrubs, vines or trees of the kind listed above, and avoid pruning them during the nesting season.
- Clutch
- Up to 36 eggs per season, one per host nest
- Incubation
- 10–12 days
- Nestling period
- 8–13 days
- Broods per year
- —
Timing shifts with latitude: nesting begins around March in Alabama but not until May in Yukon. Don't trim shrubs or clean boxes during those months.
Water, safety and patience
- A shallow bath (1–2 in deep) with a rough bottom, refreshed every 2–3 days; a dripper or heater makes it far more attractive in summer heat and winter freeze.
- Place feeders within 3 ft of windows or more than 30 ft away to cut window strikes, and keep cats indoors.
- Skip pesticides — most backyard birds feed insects to their nestlings, even seed-eaters.
- Give it time. New feeders and plantings can take days to weeks to be found; residents usually find a stocked yard first.
