Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Adults have a distinctive grey back and underparts, a black head with prominent white cheek patches, a thick, conical red bill, and pink legs. The rump and uppertail coverts are white, and the tail is black. The belly is a pale pinkish-grey.

2. 2

   Beak shape

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

   Thick, conical, and robust, adapted for cracking seeds. Bright red in adults.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown with a prominent red eye-ring.

4. 4

   Leg color

   Leg and foot color.

   Pinkish-red

5. 5

   Distinguishing features

   Standout features that separate this species.

   The combination of a black head, white cheek patches, red bill, and grey body is unique among small finches in its native range. The red eye-ring is also a key feature.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles are duller overall, with a greyish-brown head, no distinct white cheek patches (or very faint ones), a blackish-grey bill with a pinkish base, and a duller grey body. The red eye-ring is absent or very faint.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes. Plumage remains consistent year-round.

8. 8

   Sexual dimorphism

   How males and females differ.

   Males and females are generally monomorphic in plumage. Males may have a slightly larger and brighter red bill, and their eye-ring might be more intensely red, but these differences are subtle and not reliable for sexing without direct comparison or behavioral cues (e.g., singing).

Key field marks

• Head Pattern. Look for the striking black head with prominent, clean white cheek patches. This is the most distinctive feature.
• Bill Color and Shape. Note the thick, conical, bright red bill. Juveniles have a duller, blackish bill.
• Body Plumage. Observe the uniform grey back and underparts, contrasting with the black head. The rump is white.
• Eye-ring. Adults have a noticeable red eye-ring around their dark eyes.
• Behavior. Often seen in flocks, foraging on the ground for seeds, especially in open, grassy, or cultivated areas.
