Though it is widespread and abundant, its numbers have declined in some areas. The animal's conservation status is listed as least concern on the IUCN Red List. Nonbreeding males have a yellowish bill and reduced black on the breast. Song is a series of two-parted cheep or chirrup notes, given throughout much of the year. Breeding males have a broad black bib, whitish cheek, and chestnut head with gray crown. Swamp Sparrows are dark brown on the back with rusty crowns and wings.
Backyard Tips
California Towhees’ diets are mostly seeds from grasses and herbs, but they also eat berries such as elderberry, coffeeberry, and acorns. Knowing when you are most likely to spot sparrows can help reduce the guesswork with these similar-looking birds. This guide sorts these birds by when you are most likely to spot them. They have colonized just about every urban and semi-urban area throughout North, Central, and South America. Some building managers hire wildlife control companies to come in after hours and shoot these birds using pellet guns. Other try to save expense by putting out glueboard traps—perhaps the most inhumane consumer product on the market—on perching surfaces.
House Sparrow: Least Wanted Backyard Birds
House Sparrows are chunkier, fuller in the chest, with a larger, rounded head, shorter tail, and stouter bill than most American sparrows. Animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. House sparrows are well-suited for studies of general biological problems, such as the way animals evolve and pest control. House Sparrows like areas that have been modified by humans, including farms, residential, and urban areas. They are absent from uninhabited woodlands, deserts, forests, and grasslands.
Sparrows in California in Winter
House Sparrows readily eat birdseed including millet, milo, and sunflower seeds. In summer, House Sparrows eat insects and feed them to their young. They catch insects in the air, by pouncing on them, or by following lawnmowers or visiting lights at dusk. Because of their preference for human-modified habitats, house sparrows are considered a nuisance species, an aggressive competitor with native birds, and an agricultural pest. Large aggregations around buildings produce annoying noise and large quantities of feces. You can find House Sparrows most places where there are houses (or other buildings), and few places where there aren’t.
Eggs
ExclusionStarlings cannot squeeze through a hole smaller than 1 1/2”, so an entrance hole of this size or smaller will exclude starlings from boxes intended for smaller birds. House Sparrows can fit through entrance holes as small as 1 1/4”; therefore, most cavity-nesting songbirds using nest boxes are vulnerable to House Sparrow competition. There currently is no scientifically-documented way to exclude House Sparrows that works permanently, but some monitors have observed that Gilbertson PVC boxes are often avoided by House Sparrows. Your best bet may be to use a more active method of managing House Sparrows. If you prefer, you may alternatively choose to offer only boxes that are not as vulnerable to exotics (e.g., chickadee boxes, Chimney Swift Towers, or nesting platforms). Lincoln’s Sparrows are medium-sized sparrows, mainly gray in color and with streaks of brown across their wings and chest and white bellies.
These can keep birds out of doors that must remain open for long periods. If you want to offer nest space only to birds who are not house sparrows, there are several things you can do. In the long run, we can best deal with any problems house sparrows cause us through the habitat we control. For instance, prompt trash cleanup using bird-proof trash containers goes a long way to limit house sparrow activity around outdoor eateries, picnic spots and dumpsters.
Subspecies
You can find White-crowned Sparrows in weedy fields, along roadsides, forest edges, and in yards foraging for seeds of weeds and grasses or fruit such as elderberries and blackberries. White-crowned Sparrows breed in Alaska and arctic Canada before heading south to the lower 48 and Mexico for winter. However, some may remain along the Pacific Coast and the mountainous west all year. You can find Black-chinned Sparrows in arid, desert-like environments. They prefer to live in remote and rocky areas with sagebrush, pine-juniper vegetation, and other brushes and scrubs. They may move south of their breeding locations in winter, usually to lower elevations.
Nests are comprised mostly of vegetation but some clay, sand, cloth and even dung may be used (Heij, 1986). In some cities, nests also contain aromatic plants or even cigarette butts that contain antiparasitic secondary compounds (Sengupta and Shrilata, 1997). Males initially choose nesting sites and subsequently advertise for mates by vocal and visual displays (Summers-Smith, 1963). However, unlike many songbirds, males exhibit aggressive, territorial behavior only in a very small area around the nest site. Females select males based on visual and vocal displays and the location of nest sites (Anderson, 2006). Once paired, males and females often remain together for the entire season or even multiple years.

They lay up to six eggs, which take around two weeks to hatch and a further one or two weeks for the young to fledge. Savannah Sparrows breed in Canada and the US before migrating to southern US states and Mexico for winter. They lay around four eggs, which take just under two weeks to hatch and a further ten days for the young to fledge. You can find Golden-crowned Sparrow in weedy fields scratching for seeds such as dock, sumac, and geranium. They also eat fruit such as apples, grapes, elderberry, and olives.
Nests of Harris’s Sparrows are on the ground and made from twigs and moss and lined with soft grass. They lay up to five eggs which take around two weeks to hatch and a further nine days or so for the young to leave the nest. Nests of Clay-colored Sparrows are usually close to the ground and well hidden in vegetation. The female makes them from twigs and grass, and they are lined with softer grasses and animal hair.
Even conservationists often assume that common, adaptable species will be able to adapt to any change. For instance, their 1868 introduction to Philadelphia was apparently an effort to control inchworms. As with so many such pest control efforts, the cure proved worse than the disease.
You can find Sagebrush Sparrows among undisturbed sagebrush and other shrubs. In winter, they migrate to brushy saltbush lands and other desert-like areas. They lay up to six eggs, which take around two weeks to hatch and a further week to two weeks for the young to fledge. You can find Lincoln’s Sparrow mostly in densely-covered shrubs and thickets, particularly near streams and wet or damp areas.
House Sparrows and starlings prefer to be near human habitations, and starlings also frequently inhabit agricultural areas with abundant grain. Therefore, placing your nest boxes in natural areas away from densely-populated locations will prevent many non-target birds from ever finding them. As a nest box monitor, your goal is to provide a safe environment for local cavity-nesting species to breed. For the reasons outlined above, we strongly encourage that you do not allow House Sparrows or European Starlings to breed in your nest boxes. We recommend that you take measures to prevent them from breeding in your boxes.
House sparrows avoid predation by foraging in small flocks so that there are many eyes watching out for potential predators. The European House Sparrow has a story to tell about survival in the modern world. In parts of its native range in Europe, House Sparrow numbers are down by nearly 60%. A new study by Cornell Lab of Ornithology scientists aims to clarify the status of this non-native species, using 21 years of citizen science data from the Cornell Lab’s Project FeederWatch.
Introduced populations in North America were discovered to have pale coloration in hot, arid climates, but darker coloration in cooler, humid climates (Johnston and Selander, 1964). The loading docks of these buildings are often open during business hours so birds can just fly in. Some house sparrows deliberately trigger the motion sensors that automatically open store doors for customers.
Dark-eyed Juncos remain resident all year in the northeastern and western US states and the Appalachian Mountains. Those that breed in Canada and Alaska migrate south in winter to the United States. They are recorded in 21% of summer checklists and 25% of winter checklists. They do not migrate, and they appear in 31% of summer checklists and 27% of winter checklists for the state. The female sparrow begins to incubate the eggs after she lays the next-to-last egg.
