Physical features to check

1. 1

   Plumage

   Overall feather coloration and pattern.

   Males have a grey head, a bright yellow breast, and a greenish-yellow belly. The back and wings are olive-green, often with a purplish-maroon patch on the shoulder (less prominent than in some other Treron species). The undertail coverts are rufous. Females are generally duller, lacking the bright yellow breast and grey head, being mostly olive-green with a yellowish wash on the underparts. Both sexes have a yellowish-green orbital ring.

2. 2

   Beak shape

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

   Relatively short and stout, pale greenish-yellow to bluish-grey with a darker tip.

3. 3

   Eye color

   Iris color and any distinctive eye markings.

   Inner ring blue, outer ring red.

4. 4

   Leg color

   Leg and foot color.

   Red to purplish-red.

5. 5

   Distinguishing features

   Standout features that separate this species.

   The combination of a grey head and bright yellow breast in males is unique among green pigeons in its range. The rufous undertail coverts are also a good field mark.

6. 6

   Juvenile appearance

   How young birds differ from adults.

   Juveniles resemble females but are generally duller, with less distinct markings and often a more uniform greenish plumage. The yellow on the breast, if present, is very faint.

7. 7

   Seasonal changes

   Plumage variation between breeding and non-breeding seasons.

   No significant seasonal plumage changes are noted for this species.

8. 8

   Sexual dimorphism

   How males and females differ.

   Pronounced. Males are much more brightly colored with a grey head and yellow breast. Females are predominantly olive-green and lack these prominent features.

Key field marks

• Male Plumage. Look for the distinctive combination of a grey head, bright yellow breast, and olive-green body. The rufous undertail coverts are also a key feature.
• Female Plumage. Females are harder to identify, being mostly olive-green. Look for the yellowish-green orbital ring and the overall shape and size consistent with a green pigeon. Absence of strong markings helps distinguish from other Treron females.
• Vocalization. Listen for its soft, mournful, whistling coo, which is a good indicator of its presence, especially when the bird is hidden in foliage.
• Habitat and Behavior. Observe its arboreal habits, feeding on fruits in the canopy of forests or forest edges. Its shy nature means it's often heard before it's seen.
