Chorui Pakhi

 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.
