The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird. It nests in cavities, and pushed out native species like Eastern bluebirds.

They have adapted to exploit food sources that we provide to them either directly, or indirectly. The house sparrow (Passer domesticus) is a bird that most people in the United States are familiar with. Whether hopping around under the table of a coffee shop or enjoying a meal at a backyard bird feeder, these birds have adapted to live alongside humans.

Considered anthrodependent, some populations have gone extinct locally without human presence (Ravinet et al., 2018; Summers-Smith, 1988). It is for this relationship with people that they received their species identifier domesticus, which derives from the Latin domus or 'house', from Carl Linnaeus in 1758 (Jobling, 2009; Anderson, 2006). Their ubiquity and close association with humans have undoubtedly led to their detailed study across biological and even sociological disciplines.
What Do House Sparrows Eat? (Complete Guide)
House Sparrows begin nesting in February and March, and their breeding season runs through August. Their success in colonizing North America is due, in part, to their prolific breeding abilities, sometimes producing four broods in a single year. Associating with humans allows House Sparrows to capitalize on our food scraps and compete with livestock for feed.
House sparrows incubate the eggs for an average of 11 days before egg hatching. In higher latitudes which normally imply cold average temperatures, eggs take longer to hatch and may take up to 14 days. House sparrows favor open and semi-open habitats and generally do not enter woodlands. Favorite habitats include parking lots, gas stations, park-like areas, and any urban environments. They have colonized just about every urban and semi-urban area throughout North, Central, and South America.

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. They thrive on a variety of foods, including spilled grain and even garbage. As with many aspects of conservation history, many of the details of sparrow introductions are poorly documented. The first introduction to North America was to New York City in 1851 or 1852, although the 8 pairs released seemed to fare poorly. However, this set off a wave of introductions throughout the United States.
House sparrows may be highly adaptable, but that doesn’t mean they can thrive with every modification humans make to the environment. The species is listed by the Royal Society for the Protection of Birds as a species of high conservation concern. While the United Kingdom population has recently stabilized, the bird remains of concern to conservationists.

It is extensively, and usually unsuccessfully, persecuted as an agricultural pest. It has also often been kept as a pet, as well as being a food item and a symbol of lust, sexual potency, commonness, and vulgarity. 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.
She roosts inside the nest upon starting to lay eggs, but she does not incubate the eggs. Egg color ranges from light brown to greenish or bluish-white. Markings are also variable but are generally wreathed towards the wider side with a mix of gray to brown dots and spots.
There are two subspecies, the eastern and the western chipping sparrows. Western ones will breed in coniferous forests while the eastern ones choose gardens, parks, farmlands, and woodlands. They spend most of their time scratching around on the forest floor, looking for insects, though they also eat some seeds. Abert’s Towhees are a large ground-dwelling sparrow found in desert areas in California. They spend most of their time in cottonwood-willow forests and mesquite woodlands, usually close to rivers and streams.
Unfortunately, they can also outcompete and crowd out other bird species at bird feeders. House Sparrows remain wary around humans and quickly flee at the slightest hint of danger. However, they can be very aggressive towards native birds in North America, particularly when it comes to nesting. House Sparrows outcompete native North American birds like Martins and Bluebirds by occupying suitable nest cavities and even killing chicks and adult birds on nests. House Sparrows can be a pest in farming areas due to their habit of eating grain crops and stored grains and animal feeds.
These birds breed in the western parts of the USA before moving to the southern parts of the country and Mexico for winter. Green-tailed towhees are one of the larger American sparrow species. Pairs will sometimes sing together, delivering a “squeal duet” comprised of a jumble of scratchy notes. Males also have a simple solo song that’s made up of a series of ringing peep notes.
Adults will probably use this food source to feed their young, although they will also be quite happy to dine on these high-protein snacks themselves. You might spot house sparrows tearing into flowers or getting a meal up in the branches of a tree. House sparrows know that where people eat, food scraps are sure to end up on the ground, so they often hang around restaurants and park benches. Reproductive biology has been another reason this species has been used as a model, in particular to understand the cues that influence the onset of breeding. Towards the global poles, house sparrows, like other species, rely on changes in the number of hours of daylight and temperature to ensure that breeding coincides with peak food availability (Hau, 2001).
While they may seem dull, their grayish-brown coloration helps them disappear in the arid habitat. Golden-crowned Sparrows disappear into the northern tundra and shrublands during the winter but spend their summers in weedy and shrubby lowlands and along city edges. This vanishing act means that they’re one of our least-known songbirds. Grasshopper Sparrows are one of only a few sparrows in California that sing two distinct songs. One is high-pitched, buzzy, and insect-like (featured below).
These birds are highly successful in the urban and suburban landscape because they are able to capitalize on the food we put out for them and other birds. They will feed on a variety of feeder types and also pick up seeds that have fallen to the ground below feeders. House sparrows forage for food on the ground most of the time. These birds hop around actively searching for seeds and other sources of food.
