The Sparrow is mentioned 40 times in the Bible, it is reported. They have a long history.
I have found a variety of Sparrows and saw many of them at my birdfeeders.
You can find House Sparrows most places where there are houses (or other buildings), and few places where there aren’t. Along with two other introduced species, the European Starling and the Rock Pigeon, these are some of our most common birds. Their constant presence outside our doors makes them easy to overlook, and their tendency to displace native birds from nest boxes causes some people to resent them. But House Sparrows, with their capacity to live so intimately with us, are just beneficiaries of our own success.
Keys to identification
Sparrowlike
Typical Voice
-
Size & Shape
House Sparrows aren’t related to other North American sparrows, and they’re differently shaped. House Sparrows are chunkier, fuller in the chest, with a larger, rounded head, shorter tail, and stouter bill than most American sparrows.
-
Color Pattern
Male House Sparrows are brightly colored birds with gray heads, white cheeks, a black bib, and rufous neck – although in cities you may see some that are dull and grubby. Females are a plain buffy-brown overall with dingy gray-brown underparts. Their backs are noticeably striped with buff, black, and brown.

Behavior
House Sparrows are noisy sparrows that flutter down from eaves and fencerows to hop and peck at crumbs or birdseed. Look for them flying in and out of nest holes hidden behind shop signs or in traffic lights, or hanging around parking lots waiting for crumbs and picking insects off car grills.
-
Habitat
House Sparrows have lived around humans for centuries. Look for them on city streets, taking handouts in parks and zoos, or cheeping from a perch on your roof or trees in your yard. House Sparrows are absent from undisturbed forests and grasslands, but they’re common in countryside around farmsteads.
Cool Facts
- The House Sparrow was introduced into Brooklyn, New York, in 1851. By 1900 it had spread to the Rocky Mountains. Two more introductions in the early 1870s, in San Francisco and Salt Lake City, aided the bird’s spread throughout the West. House Sparrows are now common across all of North America except Alaska and far northern Canada.
- The House Sparrow takes frequent dust baths. It throws soil and dust over its body feathers, just as if it were bathing with water. In doing so, a sparrow may make a small depression in the ground, and sometimes defends this spot against other sparrows.
- The House Sparrow prefers to nest in manmade structures such as eaves or walls of buildings, street lights, and nest boxes instead of in natural nest sites such as holes in trees.
- Due to its abundance, ease to raise and general lack of fear towards humans, the House Sparrow has proved to be an excellent model organism for many avian biological studies. To date, there have been almost 5,000 scientific papers published with the House Sparrow as the study species.
- House Sparrows aggressively defend their nest holes. A scientist in 1889 reported cases of House Sparrows attacking 70 different bird species. House Sparrows sometimes evict other birds from nest holes, including Eastern Bluebirds, Purple Martins, and Tree Swallows.
- House Sparrows in flocks have a pecking order much the way chickens in a farmyard do. You can begin to decipher the standings by paying attention to the black throats of the males. Males with larger patches of black tend to be older and dominant over males with less black. By wearing this information on their feathers, sparrows can avoid some fights and thereby save energy.
- House Sparrows have been seen stealing food from American Robins and piercing flowers to drain them of nectar.
- The oldest recorded House Sparrow was 15 years 9 months old.
Habitat
Town
House Sparrows are closely associated with people and their buildings. Look for them in cities, towns, suburbs, and farms (particularly around livestock). You won’t find them in extensive woodlands, forests, or grasslands. In extreme environments such as deserts or the far north, House Sparrows survive only in the immediate vicinity of people.
Seeds
House Sparrows eat mostly grains and seeds, as well as livestock feed and, in cities, discarded food. Among the crops they eat are corn, oats, wheat, and sorghum. Wild foods include ragweed, crabgrass and other grasses, and buckwheat. House Sparrows readily eat birdseed including millet, milo, and sunflower seeds. Urban birds readily eat commercial bird seed. 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.
Nesting Facts
- Clutch Size
- 1–8 eggs
- Egg Length
- 0.8–0.9 in
2–2.2 cm - Egg Width
- 0.6–0.6 in
1.4–1.6 cm - Incubation Period
- 10–14 days
- Nestling Period
- 10–14 days
- Egg Description
- Light white to greenish white or bluish white, usually spotted with gray or brown.
- Condition at Hatching
- Entirely naked upon hatching with bright pink skin, eyes closed, clumsy.
Nest Description
House Sparrow nests are made of coarse dried vegetation, often stuffed into the hole until it’s nearly filled. The birds then use finer material, including feathers, string, and paper, for the lining. House Sparrows sometimes build nests next to each other, and these neighboring nests can share walls. House Sparrows often reuse their nests.
Nest Placement
Cavity
House Sparrows nest in holes of buildings and other structures such as streetlights, gas-station roofs, signs, and the overhanging fixtures that hold traffic lights. They sometimes build nests in vines climbing the walls of buildings. House Sparrows are strong competitors for nest boxes, too, at times displacing the species the nest box was intended for, such as bluebirds and Tree Swallows. House Sparrows nest in holes in trees somewhat less often.

Ground Forager
House Sparrows hop rather than walk on the ground. They are social, feeding in crowded flocks and squabbling over crumbs or seeds on the ground. House Sparrows are a common sight at bird feeders; you may also see them bathing in street-side puddles or dustbathing on open ground, ruffling their feathers and flicking water or dust over themselves with similar motions. From living in such close company, House Sparrows have developed many ways of indicating dominance and submission. Nervous birds flick their tails. Aggravated birds crouch with the body horizontal, shove their head forward and partially spread and roll forward their wings, and hold the tail erect. This can intensify to a display with wings lifted, crown and throat feathers standing on end, tail fanned, and beak open. Males with larger amounts of black on the throat tend to dominate over males with less black. When males display to a prospective mate, they fluff up their chest, hold their wings partially open, fan the tail, and hop stiffly in front of the female, turning sideways and sometimes bowing up and down. Sometimes, other males who spot such a display in progress will fly in and begin displaying as well. In flocks, males tend to dominate over females in fall and winter, but females assert themselves in spring and summer.
Least Concern
Nest holes in trees and nest boxes are valuable commodities for birds that require them for breeding. House Sparrows are fierce competitors for these, and their abundance can squeeze out some native cavity-nesting species. After becoming common in North American cities, House Sparrows moved out to colonize farmyards and barns during the twentieth century. With the recent industrialization of farms, House Sparrows now seem to be declining across most of their range.
