Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Males have a striking black face, throat, and upper breast, bordered by a broad white supercilium (eyebrow) and a white malar stripe (moustache). The crown is grey, and the nape is chestnut. The upperparts are streaky brown, and the underparts are off-white to pale grey. Females are duller, lacking the black face and throat; they have a greyish-brown head with a pale supercilium and a dark stripe through the eye. Juveniles resemble females but are generally paler and more streaky.

2. 2

   Beak shape

   Shape and color of the bill: a key field mark.

   Conical and stout, typical of seed-eating birds. Black in breeding males, horn-colored in females and non-breeding males.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown

4. 4

   Leg color

   Leg and foot color.

   Pinkish-brown to dark brown

5. 5

   Distinguishing features

   Standout features that separate this species.

   The male's bold black and white head pattern is unmistakable. Females are distinguished from other female sparrows by their relatively plain greyish head with a pale supercilium and lack of strong streaking on the underparts.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles resemble adult females but are generally paler, with less defined markings and a more buffy wash to their plumage. The beak is horn-colored.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   Little to no significant seasonal plumage change. The black on the male's face may appear slightly duller or browner outside the breeding season due to feather wear or slight feather tipping, but the pattern remains distinct.

8. 8

   Sexual dimorphism

   How males and females differ.

   Pronounced. Males are much more boldly marked with black, white, and chestnut on the head, while females are duller and more uniformly grey-brown.

Key field marks

• Male Head Pattern. Look for the striking black face, throat, and upper breast, sharply contrasted by a broad white supercilium and white malar stripe. The grey crown and chestnut nape are also key.
• Female Head Pattern. Observe the plain greyish-brown head with a subtle pale supercilium and a dark stripe through the eye. Lack of strong streaking on the underparts is also helpful.
• Size and Shape. A medium-sized, robust sparrow with a stout, conical bill. Its overall proportions are typical of a 'true sparrow'.
• Behavior. Often seen foraging on the ground in flocks, especially in open areas near human habitation. Their cheerful, chattering calls are also a good clue.
