Female House Sparrow

The plumage of the House Sparrow is mostly different shades of grey and brown. The sexes differ: the female is mostly buff, and the male has bolder markings and a reddish back.The male has a dark grey crown from the top of its bill to its back, and chestnut brown on the sides of its head. It has black around its bill, on its throat, and on the spaces between its bill and eyes (lores). It has a small white stripe between the lores and crown and small white spots immediately behind the eyes (post oculars), with black patches below and above them. The underpants are pale grey or white, as are the cheeks, ear coverts, and stripes at the base of the head. The upper back and mantle are a warm brown, with broad black streaks, while the lower back, rump and upper tail coverts are greyish-brown.

The female has no black markings or grey crown. Its upper parts and head are brown with darker streaks around the mantle and a distinct pale super cilium. Its under parts are pale grey-brown. The juvenile is similar to the female adult but deeper brown below and paler above. Juvenile males tend to have darker throats and white post oculars, but these features do not reliably match sex.
