Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Predominantly bright grass-green plumage. Males have a prominent golden-orange forehead, a black mask extending from the lores to the ear-coverts, and a deep violet-blue patch on the shoulder and wing-bend. A narrow blue moustachial stripe borders the black throat patch. Females are similar but lack the black throat patch and have a less extensive golden-orange forehead, often appearing more yellowish-orange, and a smaller blue moustachial stripe. Juveniles are duller green overall, lacking the distinctive facial patterns of adults, with a pale yellowish throat.

2. 2

   Beak shape

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

   Slender, slightly decurved, pointed black bill, well-adapted for probing flowers for nectar and catching insects.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Dark brown.

4. 4

   Leg color

   Leg and foot color.

   Dark grey to blackish.

5. 5

   Distinguishing features

   Standout features that separate this species.

   The combination of brilliant green body, golden-orange forehead, black face mask, and blue shoulder patch (in males) are key. The slender, slightly decurved bill is also characteristic of leafbirds.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Duller green than adults, lacking the golden forehead, black mask, and blue shoulder patches. The throat is pale yellowish-green.

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.

   Pronounced. Males have a black throat patch and a more extensive, brighter golden-orange forehead. Females lack the black throat patch and have a smaller, duller yellowish-orange forehead.

Key field marks

• Golden-orange Forehead. Look for the bright golden-orange patch on the forehead, especially prominent in males. This is a key distinguishing feature from most other leafbirds.
• Black Face Mask and Throat (Male). Males have a distinct black mask covering the lores and ear-coverts, extending into a black throat patch. This is bordered by a narrow blue moustachial stripe.
• Overall Green Plumage. The body is a vibrant, almost iridescent, grass-green. This provides excellent camouflage in the foliage.
• Blue Shoulder Patch. Observe the small but noticeable violet-blue patch on the shoulder and wing-bend, particularly visible in males.
• Slender, Decurved Bill. Note the thin, slightly curved black bill, indicative of its nectar-feeding habits.
• Vocalizations. Listen for its rich, varied, and often mimetic song, which can be a strong indicator of its presence even when hidden in the canopy.
