Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Adults have a glossy black head, neck, and upper breast, contrasting sharply with a prominent white supercilium (eyebrow). The mantle and back are black, often with a purplish-blue sheen. The wings are a striking rufous-chestnut, and the tail is long, graduated, and black with a greenish gloss. The underparts are creamy white to buff. Some subspecies may show variations in the extent of white on the underparts or the intensity of the rufous on the wings.

2. 2

   Beak shape

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

   Robust, decurved culmen, black in color.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Red to reddish-brown.

4. 4

   Leg color

   Leg and foot color.

   Blackish-grey.

5. 5

   Distinguishing features

   Standout features that separate this species.

   The prominent white supercilium is the most distinctive feature, giving the bird its common name. The combination of glossy black head, rufous wings, and long black tail is also characteristic.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles are duller than adults. Their head and neck are streaked brown and buff, the supercilium is less distinct or absent, and the upperparts are duller blackish-brown with buff streaking. The rufous wings are present but may be duller, and the underparts are buffy with some streaking or barring.

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 similar in plumage, though females are typically slightly larger than males.

Key field marks

• White Supercilium. Look for the striking white stripe above the eye, contrasting with the glossy black head. This is the most reliable field mark.
• Rufous Wings. Observe the prominent chestnut-rufous wings, which stand out against the black body. This is visible even when the bird is skulking.
• Long Tail. Note the long, graduated black tail, often held loosely or fanned slightly as it moves through vegetation.
• Behavior. Listen for its distinctive bubbling call. Watch for its skulking behavior, preferring to run and clamber through dense cover rather than fly. Its flight is heavy and low.
• Habitat. Check dense thickets, reedbeds, and tangled vegetation, especially near water or in disturbed areas.
