In the breeding season, the male gives this call repetitively, with emphasis and speed, but not much rhythm, forming what is described either as a song or an "ecstatic call" similar to a song.  A number of chewing lice occupy different niches on the house sparrow's body. song.  A few records indicate disease extirpating house sparrow populations, especially from Scottish islands, but this seems to be rare. , In North America, house sparrow populations are more differentiated than those in Europe. The eyes do not participate in photoperiodic photoreception", "The Sparrow Question: Social and Scientific Accord in Britain, 1850–1900", "Even sparrows don't want to live in cities anymore", "Changes in the House Sparrow Population in Britain", "It was once a common or garden bird. Passer confucius Bonaparte, 1853 , In southern Africa, birds of both the European subspecies (P. d. domesticus) and the Indian subspecies (P. d. indicus) were introduced around 1900. By their first breeding season, young birds generally are indistinguishable from other adults, though they may still be paler during their first year. , Juveniles are similar to the adult female, but deeper brown below and paler above, with paler and less defined supercilia. Throat: Unlike males with their dark throats and black bib, the female house sparrow has a pale buff or gray-buff throat. , Male house sparrows in breeding (left) and nonbreeding (right) plumage, Heads of a male (left) and an immature or female (right), The house sparrow often bathes in water (at left) or in dust (at right), CS1 maint: multiple names: authors list (, "Morphological differences among populations of house sparrows from different altitudes in Saudi Arabia", "The Taxonomic Status of the Italian Sparrow –, Bulletin of the British Ornithologists' Club, "Evolution in the House Sparrow.  One of the reasons for the introduction of house sparrows throughout the world was their association with the European homeland of many immigrants. , In most of Italy, the breeding species is the Italian sparrow, which has an appearance intermediate between those of the house and Spanish sparrows.  The house sparrow is a victim of interspecific brood parasites, but only rarely, since it usually uses nests in holes too small for parasites to enter, and it feeds its young foods unsuitable for young parasites. The upper back and mantle are a warm brown, with broad black streaks, while the lower back, rump and upper tail coverts are greyish brown. , Especially in warmer areas, the house sparrow may build its nests in the open, on the branches of trees, especially evergreens and hawthorns, or in the nests of large birds such as storks or magpies. From around 1560 to at least the 19th century in northern Europe, earthenware "sparrow pots" were hung from eaves to attract nesting birds so the young could be readily harvested.  They are also given small quantities of seeds, spiders, and grit. , Some variation is seen in the 12 subspecies of house sparrows, which are divided into two groups, the Oriental P. d. indicus group, and the Palaearctic P. d. domesticus group.  The IUCN estimates for the global population runs up to nearly 1.4 billion individuals, second among all birds perhaps only to the red-billed quelea in abundance (although the quelea is, unlike the sparrow, restricted to a single continent and has never been subject to human introductions). Attempts to control house sparrows include the trapping, poisoning, or shooting of adults; the destruction of their nests and eggs; or less directly, blocking nest holes and scaring off sparrows with noise, glue, or porcupine wire. It can perform complex tasks to obtain food, such as opening automatic doors to enter supermarkets, clinging to hotel walls to watch vacationers on their balconies, and nectar robbing kowhai flowers. , Most house sparrows do not move more than a few kilometres during their lifetimes. In response, a female will adopt a threatening posture and attack a male before flying away, pursued by the male.  The oldest recorded captive house sparrow lived for 23 years. The male helps, but can only cover the eggs rather than truly incubate them. The underparts are pale grey or white, as are the cheeks, ear coverts, and stripes at the base of the head. It now occurs almost continuously from Tierra del Fuego to the fringes of the Amazon basin, with isolated populations as far north as coastal Venezuela.  The typical ratio of males to females in a population is uncertain due to problems in collecting data, but a very slight preponderance of males at all ages is usual.

Grit can be either stone, often grains of masonry, or the shells of eggs or snails; oblong and rough grains are preferred. , The female has no black markings or grey crown. Central Asian house sparrows, which migrate and have only one clutch a year, average 6.5 eggs in a clutch. Birds at higher latitudes, colder climates, and sometimes higher altitudes are larger (under Bergmann's rule), both between and within subspecies. It usually uses deserted nests, though sometimes it usurps active ones by driving away or killing the occupants.  Another vocalisation is the "appeasement call", a soft quee given to inhibit aggression, usually given between birds of a mated pair. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.  This status came to widespread attention after a female house sparrow, referred to as the "Dominomus", was killed after knocking down dominoes arranged as part of an attempt to set a world record. , Males take up nesting sites before the breeding season, by frequently calling beside them. The animal's conservation status is listed as least concern on the IUCN Red List. Sparrows were also trapped as food for falconers' birds and zoo animals. The sexes exhibit strong dimorphism: the female is mostly buffish above and below, while the male has boldly coloured head markings, a reddish back, and grey underparts.  In most of eastern Asia, the house sparrow is entirely absent, replaced by the Eurasian tree sparrow. Wear and preening expose many of the bright brown and black markings, including most of the black throat and chest patch, called the "bib" or "badge".  Finally, house sparrows in constant darkness could be entrained to a cycle of high and low temperature, but only if the difference in temperature was large (38 °C versus 6 °C); some of the tested sparrows matched their activity to the warm phase, and others to the cold phase.  Young birds also give a true song, especially in captivity, a warbling similar to that of the European greenfinch. Birds of the P. d. domesticus group have grey cheeks, while P. d. indicus group birds have white cheeks, as well as bright colouration on the crown, a smaller bill, and a longer black bib.
