They are also known as true sparrows, or sparrows, names also used for a particular of the family,. They are distinct from both the, in the family, and from a few other birds sharing their name, such as the of the family. Many species nest on buildings and the and, in particular, inhabit cities in large numbers, so sparrows are among the most familiar of all wild birds. They are primarily, though they also consume small.

At, India Generally, sparrows are small, plump, brown and grey birds with short tails and stubby, powerful. The differences between sparrow species can be subtle. Members of this family range in size from the ( Passer eminibey), at 11.4 centimetres (4.5 in) and 13.4 grams (0.47 oz), to the ( Passer gongonensis), at 18 centimetres (7.1 in) and 42 grams (1.5 oz). Sparrows are physically similar to other seed-eating birds, such as, but have a vestigial dorsal outer and an extra bone in the tongue.

This bone, the preglossale, helps stiffen the tongue when holding seeds. Other adaptations towards eating seeds are specialised bills and elongated and specialised. Taxonomy and systematics [ ]. Painting of The family Passeridae was introduced (as Passernia) by the French in 1815. Under the classification used in the ( HBW) main groupings of the sparrows are the true sparrows (genus ), the (typically one genus, Montifringilla), and the rock sparrows ( and the ).

Any of various small birds of the family Emberizidae, having brownish or grayish plumage and found throughout the Americas, such as the song sparrow.

SPARROW Mappers: Web-Based Interactive Water-Quality Mapping Systems These interactive tools allow the user to explore river nutrient loads and yields and the importance of different sources of contaminants in a particular river basin.

These groups are similar to each other, and are each fairly homogeneous, especially Passer. Some classifications also include the sparrow-weavers ( ) and several other African genera (otherwise classified among the, Ploceidae) which are morphologically similar to Passer. According to a study of molecular and skeletal evidence by and colleagues, the of the Philippines, previously considered to be a, is a sister taxon to the sparrows as defined by the HBW.

They therefore classify it as its own subfamily within Passeridae. Many early classifications of the sparrows placed them as close relatives of the weavers among the various families of small seed-eating birds, based on the similarity of their breeding behaviour, bill structure, and moult, among other characters. Some, starting with P. Suskin in the 1920s, placed the sparrows in the weaver family as the subfamily Passerinae, and tied them to Plocepasser. Another family sparrows were classed with was the (Fringillidae). Some authorities previously classified the related of the Old World and as members of the Passeridae.

Like sparrows, the estrildid finches are small, gregarious and often colonial seed-eaters with short, thick, but pointed bills. They are broadly similar in structure and habits, but tend to be very colourful and vary greatly in their. The 2008 Christidis and Boles scheme lists the estrildid finches as the separate family Estrildidae, leaving just the true sparrows [ ] in Passeridae. Despite some resemblance such as the seed-eater's bill and frequently well-marked heads, American sparrows, or sparrows, are members of a different family,, with 22 genera recognised. Several species in this family are notable singers. American sparrows are related to Old World buntings, and until 2017, were included in the Old World bunting family. The or dunnock ( Prunella modularis) is similarly unrelated.

It is a sparrow in name only, a of the old practice of calling more types of small birds 'sparrows'. A few further bird species are also called sparrows, such as the, an estrildid finch. Google Toolbar Update there. According to Luis Allende and colleagues, sparrows seem to have a parental species ( ). They are not closely related to. A male in southeastern Turkey The sparrows are indigenous to, and.

In the,, and other parts of the world, settlers imported some species which quickly naturalised, particularly in urban and degraded areas. House sparrows, for example, are now found throughout, (every state except ), parts of southern and eastern Africa, and over much of the heavily populated parts of. The sparrows are generally birds of open habitats, including,, and.

The snowfinches and ground-sparrows are all species of high latitudes. A few species, like the Eurasian tree sparrow, inhabit open. The aberrant has the most unusual habitat of the family, inhabiting the canopy of in the Philippines.

Behaviour and ecology [ ]. Seen here on the coast of, are highly gregarious outside of the breeding season. Sparrows are generally social birds, with many species breeding in loose colonies and most species occurring in flocks during the non-breeding season. The is an exception, breeding in solitary pairs and remaining only in small family groups in the non-breeding season. Most sparrows form large roosting aggregations in the non-breeding seasons that contain only a single species (in contrast to multi-species flocks that might gather for foraging). Sites are chosen for cover and include trees, thick bushes and reed beds. The assemblages can be quite large with up to 10,000 house sparrows counted in one roost in Egypt.

Sparrows water bathing near in, The sparrows are some of the few passerine birds that engage in. Sparrows will first scratch a hole in the ground with their feet, then lie in it and fling dirt or sand over their bodies with flicks of their wings. They will also bathe in water, or in dry or melting snow. Water bathing is similar to dust bathing, with the sparrow standing in shallow water and flicking water over its back with its wings, also ducking its head under the water. Both activities are social, with up to a hundred birds participating at once, and is followed by preening and sometimes group singing. Relationships with humans [ ] Sparrows may be the most familiar of all wild birds worldwide.

Many sparrow species commonly live in agricultural areas, and for several, human settlements are a primary habitat. The Eurasian tree and house sparrows are particularly specialised in living around humans and inhabit cities in large numbers. 17 of the 26 species recognised by the Handbook of the Birds of the World are known to nest on and feed around buildings. Grain-eating species, in particular the house and Sudan golden sparrows, can be significant agricultural pests. Sparrows can be beneficial to humans as well, especially by eating insect pests.

Attempts at the large-scale control of sparrows have failed to affect sparrow populations significantly, or have been accompanied by major increases in insect attacks probably resulting from a reduction of sparrows, as in the in 1950s China. Because of their familiarity, the house sparrow and other sparrows are frequently used to represent the common and vulgar, or the lewd.

Birds usually described later as sparrows are referred to in many works of ancient literature and religious texts in Europe and western Asia. These references may not always refer specifically to sparrows, or even to small, seed-eating birds, but later writers who were inspired by these texts often had the house sparrow and other members of the family in mind. In particular, sparrows were associated by the ancient Greeks with, the goddess of love, due to their perceived lustfulness, an association echoed by later writers such as and. Jesus's use of 'sparrows' as an example of divine providence in the also inspired later references, such as that in Shakespeare's and the.
