Description:
House
Sparrows also known as ‘Chorui Pakhi’ are well-known bird in Bangladesh. They
are usually seen in small to medium-sized groups, but may occur in huge
numbers. The male has a conspicuous grey crown, black face and throat, and dark
black and brown upperparts. The remainder of the under parts are pale
grey-brown. When breeding, the black of the throat extends to the chest and
upper belly. The bill also changes from brown to black. The female is slightly
paler than the male and lacks the grey crown and black face, instead having a
pale buff eye stripe. Young House Sparrows are similar to the adult female, but
are duller with some mottling on the crown, and have a darker bill.

Breeding
|
Male and female House Sparrows form permanent pair bonds.
Both sexes build the nest and care for the young, though the female alone
incubates the eggs. The nest is a large, untidy ball of grass, wool and
feathers, lined with feathers and finer plant material. It is usually located
in suitable areas in buildings, such as roof voids and crevices in walls, but
may be placed under bridges, in thick bushes or in tree hollows. Several
broods may be produced in the extended breeding season.
