House Sparrow: Least Wanted Backyard Birds
House sparrows aren't popular among birders, and for good reason. Learn more about them to better deal with these birds at your feeders and nest boxes.
What Does a Male and Female House Sparrow Look Like?
The male house sparrow has a gray and rusty crown with pale cheeks and a black bib; the female is rather plain with dusty brown overall coloring, strong stripes on her back and patches of pale feathers behind her eyes.
Are House Sparrows Invasive?
Yes, house sparrows are an invasive bird species. A nonnative to North America, they were introduced from Europe to New York in 1852. Birders tend to dislike them because they often kill native birds in order to take over their nesting sites (i.e. bluebird boxes or purple martin houses).
If you notice that house sparrows are having a negative impact on native birds nesting in your yard, there are methods you can employ to discourage them. Since they are invasive, it is legal to remove their nests. You might also try plugging the birdhouse hole until the sparrows move on.
What Do House Sparrows Eat?
These birds have a plant-based diet and tend to focus on seeds; they especially enjoy cracked corn and millet. They also might munch on flower petals or leaves. House sparrows aren’t particularly picky about what they eat, though — you may find them everywhere from at your feeders to munching on crumbs on the grounds of an outdoor restaurant.
To get rid of them, put your feeders away until they move on. House sparrows won’t stick around where there isn’t an easy food source.
Psst—here’s how to get rid of blackbirds and grackles at your feeders.

This species is not known as a particularly musical songbird. House sparrows give a short, simple chirp call.

House Sparrow Nest Habits
Nests tend to be loosely built and messy, incorporating typical nesting materials like twigs as well as scraps of general debris. They typically nest in cavities in trees or other structures, but they’ll occasionally build their nests in more open, unusual spaces like streetlights or gas station roofs.
House sparrows build nests year-round. They display fierce aggression during nesting season and compete with other birds for nesting sites, especially bluebirds.
