sind sparrow

The Sind sparrow is very similar to the house sparrow, and both sexes resemble their counterparts of that species, but it is slightly smaller and males and females each have features that distinguish them as Sind sparrows. The Sind sparrow is 13 cm (5.1 in) long, while the common South Asian subspecies of the house sparrow, Passer domesticus indicus, is 15 cm (5.9 in) long. Wingspans range from 6.2 to 7.0 cm (2.4 to 2.8 in), tails from 4.7 to 5.7 cm (1.9 to 2.2 in), and tarsi measure 1.6–1.9 centimetres (0.63–0.75 in).[2] The breeding male has a short and narrow black bib and a broad chestnut eye stripe that does not meet the mantle. The male has a grey crown and nape and a rufous lower back and rump. The female has a darker and greyer crown and cheek than the female house sparrow and the shoulder is darker chestnut.[3] The female Dead Sea sparrow of the subspecies Passer moabiticus yattii is also similar to the female Sind sparrow, but has yellow tinges on the underparts and sometimes on parts of the head.[5][6] The bill is black on the breeding male and pale brown on the non-breeding male and female. With a culmen length of 1.1–1.3 centimetres (0.43–0.51 in), the Sind sparrow is slightly smaller-billed than the house sparrow. The Sind sparrow's chirping chup call is softer, less strident, and higher pitched than that of the house sparrow, and is easily distinguished.

The Sind sparrow has a restricted distribution, primarily occurring within the Indus valley of Pakistan, and the lower parts of the tributaries of the Indus in the Punjab region. Its distribution extends from the Indus Delta north to the Kabul River near Nowshera and the Jhelum near Nurpur Noon, extending east into India as far as the Delhi area. It also breeds locally in parts of Pakistan's western province of Balochistan, and has been recorded several times in south-eastern Iran. The Sind sparrow is somewhat common in its restricted breeding range, and no threats are known to the survival of the species, so it is assessed as least concern on the IUCN Red List.
During winter, it often makes short distance movements, and some birds move into parts of western Pakistan and an adjoining corner of Iran, and less commonly north-western Gujarat, India. Longer movements may occur, as suggested by a possible sighting in the United Arab Emirates in November 2000.

Mainly seeds, mostly of grasses and small herbs; also some invertebrate food, e.g. caterpillars of Lepidoptera.

The song of breeding males includes chirrups interspersed with grating t-r-r-rt notes and short warbles or whistles.

The Sind sparrow (Passer pyrrhonotus) is a passerine bird of the sparrow family Passeridae found around the Indus valley region in South Asia. It is also known as the jungle Sind jungle or rufous-backed sparrow. Very similar to the related house sparrow it is smaller and has distinguishing plumage features. As in the house sparrow the male has brighter plumage than female and young birds including black markings and a grey crown. Distinctively the male has a chestnut stripe running down its head behind the eye and the female has a darker head than other sparrow species. Its main vocalisations are soft chirping calls that are extended into longer songs with other sounds interspersed by breeding males. Historically this species was thought to be very closely related to the house sparrow but its closest evolutionary affinities may lie elsewhere. The species was discovered around 1840 but went undetected for several decades afterwards. Within its Indus valley breeding range in Pakistan and western India the Sind sparrow is patchily distributed in riverine and wetland habitats with thorny scrub and tall grass. During the non-breeding season some birds enter drier habitats as they disperse short distances from their breeding habitat or migrate into western Pakistan and the extreme east of Iran. Since this species is fairly common and expanding its range it is assessed as least concern on the IUCN Red List. The Sind sparrow is social while feeding and gathers in small groups both while breeding and during winter dispersal. It feeds mostly on seeds and less often on insects foraging close to the ground. Nests are made in the branches of thorny trees and are untidy globular masses constructed from grass or other plant matter and lined with softer material. Both sexes are involved in building the nest and caring for the young and usually raise two clutches of three to five young each breeding season.
