Committee's view
No doubts were raised by the committee regarding the bird's identification, but some discussion points were raised regarding provenance, summarised here.


  1. This is a lowland monsoon forest species that typicall does not exhibit vagrancy; it is not known outside of Indochina.
  2. Treron pigeons are actively traded in the aviculture and the bird could be from a private collection or a shop; many birds in Singapore are likely brought in from neighbouring countries like Malaysia, Thailand and Vietnam.
  3. Subsequent record will better improve this species understanding, and till greater clarity is achieved it should be treated as an escapee.


  1. Lack of records in Malaysia for rarities showing up in Singapore is not unusual given Singapore's high observer density.
  2. Treron pigeons typically stay within their range and travel large distances within in search for food, but occasional vagrancy is exhibited (see eBird range maps for Wedge-tailed, Pin-tailed Green-Pigeons, and Yellow-vented Green Pigeon; see Wells (1999) for Thick-billed and Yellow-vented Green Pigeons). Parallels were drawn to Singapore's first Orange-breasted Green Pigeon record.
  3. Record was during migratory season and in the Central Catchment forest.
  4. Treron pigeons are barely, if ever, recorded during trade surveys (see numerous published TRAFFIC surveys and others). It is a highly niche collection.

Others: feather conditions
Pristine feathers were observed in this bird, which some take as supportive of wild birds, but points were noted that top collectors can keep their birds with minimal feather damage.
