1-8-2018 TANCAT DE LA RATLLA, VALENCIA - EURASIAN TREE SPARROW (MALE) (Passer montanus)


The Eurasian tree sparrow (Passer montanus) is a charming passerine bird, easily recognized by its rich chestnut crown and nape, and a distinctive black patch on each pure white cheek. Both sexes are similarly adorned, and the juveniles mirror the adults, albeit with slightly duller hues. This species is somewhat smaller than the closely related house sparrow, and its size is approximately 12.5–14 cm in length, with a wingspan of about 21 cm.

To identify the Eurasian tree sparrow, look for the kidney-shaped black ear patch on each white cheek, the black chin and throat, and the light brown upperparts streaked with black. The wings bear two narrow white bars, and the legs are pale brown. The bill is lead-blue in summer, darkening almost to black in winter. Unlike the house sparrow, there is no sexual dimorphism in plumage, making both males and females equally easy to identify.

In Europe, the Eurasian tree sparrow is typically found in lightly wooded open countryside, while in eastern Asia, it is more common in urban settings. It prefers nesting in natural cavities, holes in buildings, or even the abandoned nests of other large birds. This species is not typically found in mountainous regions, despite its scientific name suggesting otherwise.

The Eurasian tree sparrow has a broad distribution across temperate Eurasia and Southeast Asia, and it has been introduced to other regions such as the United States. Its range extends from Europe across Asia to the Lena River and south to the northern regions of Turkey, the Caucasus, Kazakhstan, Mongolia, and North Korea.

The Eurasian tree sparrow is a sociable bird, often seen in flocks. It is sedentary in most of its range, but northern populations may migrate southward in winter. This species is known for its untidy nests and can breed in a variety of locations, from tree holes to urban structures.

The Eurasian tree sparrow does not have a true song but communicates with a series of excited "tschip" calls during courtship and other monosyllabic chirps for social interactions. Its flight call is a harsh "teck."

Breeding maturity is reached within a year, and the typical clutch consists of five or six eggs. Both parents incubate the eggs for about 12-13 days, and the chicks fledge after 15-18 days. The species may raise two or three broods each year.

Primarily a seed and grain eater, the Eurasian tree sparrow forages on the ground in flocks. During the breeding season, it also consumes invertebrates to feed its young. It is known to visit feeding stations, particularly for peanuts.

10-3-2017 PEGO MARJAL, ALICANTE - EURASIAN TREE SPARROW (MALE) (Passer montanus)



The Eurasian tree sparrow (Passer montanus) is asmall passerine bird that breeds over most of temperate Eurasia and Southeast Asia, where it is known as the Tree sparrow. It has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native unrelated American tree sparrow.

The adult's crown and nape are rich chestnut, and there is a kidney-shaped black ear patch on each pure white cheek; the chin, throat, and the area between the bill and throat are black. The upperparts are light brown, streaked with black, and the brown wings have two distinct narrow white bars. The legs are pale brown, and the bill is lead-blue in summer, becoming almost black in winter. This sparrow is distinctive even within its genus in that it has no plumage differences between the sexes; the juvenile also resembles the adult, although the colors tend to be duller. Its contrasting face pattern makes this species easily identifiable in all plumages; the smaller size and brown, not grey, crown are additional differences from the male house sparrow. Adult and juvenile Eurasian tree sparrows undergo a slow complete molt in the autumn and show an increase in body mass despite a reduction in stored fat. The change in mass is due to an increase in blood volume to support active feather growth and generally higher water content in the body.The adult's crown and nape are rich chestnut, and there is a kidney-shaped black ear patch on each pure white cheek; the chin, throat, and the area between the bill and throat are black.

4-1-2016 STANLEY, HONG KONG - EURASIAN TREE SPARROW (MALE) (Passer montanus)


The tree sparrow is the house sparrow’s country cousin but its name is misleading: in Britain it prefers arable farmland and rural gardens to woodland.

Its Latin name, Passer montanus, is equally confusing for it isn’t a bird that favours mountains in Europe, though it breeds at up to 2,500m in the Himalayas.

Tree sparrows have a far greater natural distribution worldwide than the house sparrow: they are found throughout much of Europe and Asia, and east to Indonesia and Japan.

There are six recognised sub-species of tree sparrow but they differ little in appearance. The smallest individuals occur in the extreme south of the birds’ range.

In the west of its extensive range the tree sparrow prefers more rural areas to the house sparrow, but in the east (where the house sparrow is absent) it is often found in the centre of towns and villages.

This sparrow was introduced to St Louis, Missouri, USA, in 1870; the population still exists today, extending north to the towns of Virginia and Springfield.

An attempt to establish tree sparrows in New Zealand in 1868 eventually ended in failure.


In 1958 Mao Tse Tung’s Marxist government ordered the extinction of sparrows, which were regarded as pests. Millions were killed (all tree sparrows) before it was discovered that because the sparrows ate insects as well as grain they were in fact highly beneficial.

Tree sparrow populations in the British Isles fluctuate. However, the last 40 years have seen a huge decline, due largely to agricultural changes.
Britain’s tree sparrow population is thought to number just 10% of size of the population in the late 1960s.

Unlike house sparrows, both sexes of tree sparrows are identical in appearance, with no seasonal change in plumage.

Like their house sparrow cousin, tree sparrows are sociable birds and usually found in small flocks. They like to breed in small, loose colonies, too.
In areas where they occur they are readily attracted to bird feeders. Though reputedly keen on millet, they are also enthusiastic consumers of sunflowers, and especially sunflower hearts.

Though the adults are chiefly seed-eaters, the young depend on a diet of insects.

Unlike the stay-at-home house sparrow, tree sparrows wander far more, with many moving between breeding and wintering areas.

A number of British-ringed tree sparrows have been caught on the Continent, and birds ringed in the Netherlands, Belgium and France have been found in England.

They are hole-nesters and will readily use nest boxes. Colonies can be established by providing a number of suitable nest boxes in a small area.
Where conditions are favourable, breeding success can be high, with pairs rearing two or sometimes three broods a year.

The clutch size ranges from two to seven eggs. They take 11-14 days to hatch, with the young fledging in 15 to 20 days.

Once a pair bond has been established, the two birds remain in company for much of the time, feeding, bathing and preening together.

During the winter these sparrows like to roost in holes, and they will also use nest boxes for roosting.

30-11-2015 ANGKOR WAT, CAMBODIA - EURASIAN TREE SPARROW (MALE) (Passer montanus)


The Eurasian tree sparrow (Passer montanus) is a passerine bird in the sparrow family with a rich chestnut crown and nape and a black patch on each pure white cheek. The sexes are similarly plumaged, and young birds are a duller version of the adult. This sparrow breeds over most of temperate Eurasia and Southeast Asia, where it is known as the tree sparrow, and it has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native unrelated American tree sparrow. Although several subspecies are recognised, the appearance of this bird varies little across its extensive range.

The Eurasian tree sparrow's untidy nest is built in a natural cavity, a hole in a building, or the disused nest of a European magpie or white stork. The typical clutch is five or six eggs which hatch in under two weeks. This sparrow feeds mainly on seeds, but invertebrates are also consumed, particularly during the breeding season. As with other small birds, infection by parasites and diseases, and predation by birds of prey take their toll, and the typical life span is about two years.

The Eurasian tree sparrow is widespread in the towns and cities of eastern Asia, but in Europe, it is a bird of lightly wooded open countryside, with the house sparrow breeding in the more urban areas. The Eurasian tree sparrow's extensive range and large population ensure that it is not endangered globally, but there have been large declines in western European populations, in part due to changes in farming practices involving increased use of herbicides and loss of winter stubble fields. In eastern Asia and western Australia, this species is sometimes viewed as a pest, although it is also widely celebrated in oriental art.
