They can be also identified by their high-pitched squeals, nasal “wiks“, and strong “piuu-piuu” calls. Ochre-breasted brushfinches are found in the understory of montane forests and edges – they are common in Colombia and Venezuela, at elevations from 3,200 to 11,500 feet. They love to remain hidden in dense vegetation which makes it hard to spot them. California Towhees are among the most uniformly drab sparrows in California but have managed to become a bit well-known anyway. Lark Sparrows breed in California in open grasslands with scattered forests nearby, like open woodlands and orchards.

Males are easy to identify because they’re almost all black, unlike any other sparrows in California.
The House Sparrows compete with many native birds, such as bluebirds and Purple Martins, for nest cavities. Unfortunately, these invasive species tend to win more times than not. By the 1880s, just three decades after the first introduction, several U.S. cities paid bounties for the birds.
Where do House Sparrows nest?
Their long legs allow them to wade in shallow water and catch prey. At this time of year, the males puff up and display, making them appear like much larger birds. House sparrows need to eat many times every day to maintain their metabolism. In fact, small birds like sparrows need to eat as much as half their own body weight each day. This specific article provides a summary of our current knowledge on the biology and evolution of the house sparrow, and discusses its place as a model species for biological insight.

Their worldwide populations are huge numbers, but populations in some regions are on the decline. These birds look like house sparrows but have reddish-brown instead of gray crowns of house sparrows. Spanish sparrows are very noisy birds that often make “churp” flight calls, “que-que” contact calls, “quer” alarm calls, and fast “cheeli-cheeli” calls to attract females. When the breeding season comes, they will make huge groups with hundreds and thousands of birds.

House Sparrows are found virtually throughout the United Kingdom, except for high-lying areas in Scotland and Northern England. These familiar birds are most common in towns, villages, and farmlands and frequently visit garden bird tables. The House Sparrow has an extensive distribution on every continent except Antarctica.

However, they are protected by the Wildlife and Countryside Act in the United Kingdom, where they are a native species. House Sparrows that survive to adulthood have a typical lifespan of about three years. Wild birds can live for over 13 years, and one captive specimen reportedly survived 23 years.
They inhabit cities, parks, suburbs, backyards, farms, orchards, and any number of different manmade habitats. Their flexibility is the primary reason why they are such a successful invasive species. Nowadays, you can find them in North, Central, and South America, as well as Eurasia, Africa, and Australia. They often live in cities, parks, suburbs, farms, and other urban areas. Nests tend to be loosely built and messy, incorporating typical nesting materials like twigs as well as scraps of general debris. They typically nest in cavities in trees or other structures, but they’ll occasionally build their nests in more open, unusual spaces like streetlights or gas station roofs.

Just as modification to a tropical forest affects wildlife, so too do changes in farming practices, changes in city design, even changes in bird feeding habits. House sparrows enjoy hearted peanuts but they can struggle with whole peanuts in their shells because of the size of this food source. Prior to the annotated genome, a high-density single-nucleotide polymorphism (SNP) array was developed for the species (Hagen et al., 2013; Lundregan et al., 2018). The female sparrow begins to incubate the eggs after she lays the next-to-last egg.
The article gives a lot of detail on the epigenetic basis of phenotypic plasticity in house sparrows. This is not that surprising given a lot of the work on the system is done by the authors. The reviewers, however, felt it would be better to balance this with a bit more on the recent evolutionary genomics on the species. For example, the Italian sparrow is mentioned only in passing but it is quite an important aspect of why this study system is so interesting to speciation research. Work by Elgvin et al., 2017 and 2011, Hermansen et al., 2014, and Trier et al., 2014 is worth looking at. A tendency to eat novel foods may benefit birds in habitats where resources are scarce or unfamiliar, but such behavior could also come with risks.

House Sparrows are an introduced, non-native species in North America. They were first brought over from Europe in 1851 and spread rapidly south and east. Supplemented with introductions in California and Utah, the species has now colonized most of the United States, Canada, Mexico, and Central America. House Sparrows occur everywhere in North America except Alaska and Northern Canada. Look out for these birds in cities, towns, parks, and farming areas in every state.
This species is monogamous and usually only breeds with one partner for a season. Females lay an average of five eggs per clutch, and both sexes participate in incubation duties. They spend their day hopping along the ground in search of food or flitting from branch to branch. While they are not breeding, they are quite social birds, and forage in small groups known as flocks.
Nonbreeding males are streaked brown, black, and buffy above and dingy below. They lack the bright chestnut neck and extensive black bib of breeding males. Females are a plain buffy-brown overall with dingy gray-brown underparts. Their backs are noticeably striped with buff, black, and brown. They are omnivores that mostly feed on seeds, grains, and fruits, but will also take insects, especially during the breeding season.
They will visit bird baths and bowls but also drink from gutters, puddles, and water features, as well as ponds, streams, and lakes. House sparrows are one of the most ubiquitous birds in the world (Anderson, 2006). In approximately 170 years, they colonized the globe such that they now reside in every continent except Antarctica and occupy an estimated 76,600,000 km2 (Birdlife international, 2018). There have been over 250 introduction or translocation events recorded worldwide (Table 1), with the first deliberate successful introduction occurring in 1851 in New York City (Summers-Smith, 1988). Many introductions stemmed from colonial acclimatization societies purposefully releasing birds for cultural reasons or as failed attempts at biological control.
This approach also justifies important areas of future study for our focal species. As new technologies are developed and refined, we expect the interest in house sparrow genetics, epigenetics and the microbiome to grow. Several local populations of house sparrows have been pedigreed, which enables quantitative genetic estimates of heritability and genetic architecture (Schroeder et al., 2015; Jensen et al., 2003; Wetzel et al., 2012).
The song varies depending on location and the individual bird. Even conservationists often assume that common, adaptable species will be able to adapt to any change. House sparrows do not excavate cavities nor enhance existing structures to fit their needs. The exterior part of the nest is built with coarse material, including dry grasses, twigs, pieces of plastic, paper, and strings.
