Subspecies also differ in size, mass and male plumage (See Summers-Smith, 1988). They are social, feeding in crowded flocks and squabbling over crumbs or seeds on the ground. From living in such close company, House Sparrows have developed many ways of indicating dominance and submission. 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.
Range & Identification
Sparrows mainly eat seeds and insects, and they will often come to backyard feeders. Find out the other species of birds that regularly visit California and print a free ID chart. Once sparrows are inside, they can be removed humanely by catching them with nets or in live-traps. This short-term solution removes the bird without killing, but it obviously is not a long-term solution to this problem. Only by working with store managers on more comprehensive strategies can the issue of problem birds in stores be successfully addressed and resolved.
Grasshopper Sparrow
The sparrows, according to the research, diverged from other Old World sparrows around 11,000 years ago, just as agriculture was taking hold in the Middle East. The house sparrow (Passer domesticus) is native to Eurasia, but beginning in the mid-1800s, it spread around the globe. Largely due to intentional releases by humans, house sparrows are now found on every continent except Antarctica, as well as many islands. 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.

Clay-colored Sparrows are not very common in California, but they are recognized as regularly occurring here during fall migration. They are found on the ground in dry habitats in dense undergrowth by desert streams and riverbeds in a very small area predominantly in southwestern Arizona. You can find Lark Sparrows on the bare, open ground like grasslands, but they also favor trees and pastures with a few scattered shrubs.
Nesting
They are lined with softer material, such as animal hair, grass, and feathers. Black-chinned Sparrows are plain and mainly gray overall but with brown backs and wings. Males have the black patch on their throat, but the females and non-breeding males don’t.
Songs and Calls
House sparrows can build adjacent nests sharing common walls. Nests built in cavities, nesting boxes, and other types of enclosures do not usually have any roofing but only a cup, particularly when the enclosure is small. Large enclosures tend to be filled with nesting material with a central cup. In North America, the first eggs have been recorded in early March, and the last dependent chicks have been observed in late September. The onset of the breeding season is influenced by temperature.
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. Compared to breeding males, nonbreeding and immature males have less black on the throat and breast and a yellowish (not black) bill. This individual shows a yellow gape typical of a recently fledged bird. They breed in the far north of Canada and in Alaska and migrate to most US states for the winter, except the Pacific and Gulf Coasts.
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.
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.
Rufous-crowned Sparrows are large sparrows that are gray underneath and streaked brown on the back. They have reddish-brown crowns and white and dark stripes on their faces. Nests of Spotted Towhees are usually on or near the ground and made from leaves, stems, and bark lined with softer material. They lay up to six eggs, which take around two weeks to hatch and a further ten days for the young to fledge. Nests of Dark-eyed Juncos are usually on the ground, hidden in vegetation, woven from plant material, and lined with grass and hair.
Sparrows are often described as ‘little brown jobs’ by birders so it is obvious that it can be a challenge for even an experienced birder to recognize them. The reviewers felt that this was a well-written and entertaining short review on a study species for which "there is surprisingly little general literature".
