Bird List Revision for September 2021 – Special Edition

The Singapore Birds Project checklist is updated regularly according to taxonomic updates by the International Ornithological Committee ↗ (IOC). Our team recently conducted a thorough review to vote on additional species to be added to or removed from the checklist. In the spirit of ensuring that accurate information is provided in a timely fashion, we decided to release a Special Edition prior to the next IOC update. The downloadable list (in Excel format) is available HERE.

Along with this update, we would like to welcome Raghav to the team. Our growing Singapore Birds Project main team consists of Keita Sin (chair), Sandra Chia (vice-chair), Dillen Ng, Francis Yap (site admin), Movin Nyanasengeran and Raghav Narayanswamy. Many of you have provided us generous comments for our work which we are very grateful for. Suggestions and constructive criticisms, as always, are strongly welcome! Please feel free to reach out to us via the Contact Us section.

A write-up of how our checklist operates will be released soon. In the mean time, here are the details for the changes to the checklist.

Added

Orange-breasted Green Pigeon: A vagrant to Singapore with a single record of a male from Japanese Garden on 22 December 2007.

Masked Lapwing: This species native to Australia has breeding records dating back to at least 2004. The growing population seems to be sustainable and recent sightings include a flock of ~50 birds along a canal in Bedok.

Javan Plover: A single, very likely breeding record from Pulau Tekong in mid-2021. More records of this expanding species might be expected in the near future.

Milky Stork and Painted Stork: Both species of storks have been introduced to Singapore since at least 1987. Their breeding is indicated by ever-present juveniles at multiple sites in Singapore coupled with the numerous nests around Mandai. A recent genomic analysis by Baveja et al (2019) revealed an alarming result that many of the storks in Singapore are hybrids at some level. However, some genetically pure Milky Stork still exists. The Painted Storks sampled in the study were at best backcrosses between first generation hybrids and pure ones, but this species is also added to the checklist on balance that evidence suggest the presence of pure individuals.

Pied Kingfisher: A single record from Punggol on 18 September 1995. The same species was recorded at Southern Johor in early 2016 ↗ as well.

Crimson-winged Woodpecker: Sightings from Bukit Timah in 2001, at least one of which was accompanied by sketches. Several other reports continuing up to 2008 are unsubstantiated thus far.

Monk Parakeet: This species is native to South America and has been present since at least 2009, with nesting records dating back to 2012. The presence of multiple breeding records coupled with the recent westward expansion is indicative of an alarming population growth.

Velvet-fronted Nuthatch: Multiple sightings of a single individual in Bukit Timah from 1996 to 1999. A non-breeding visitor to Singapore.

Red-billed Starling: A total of four records in Singapore. While the provenance of each specific record remains to be assessed, increasing evidence of vagrancy from Indochina and the Philippines are indicative that wild birds occur in Singapore.

Golden-backed Weaver: The proliferation of this species in suitable habitats has been highly visible. Strongholds at Kranji Marshes and Lorong Halus show that this species is clearly well-established. The obvious displacement of native Baya Weavers is worrying.

Deleted

Yellow-crested Cockatoo: This introduced species only occurs in small numbers in Singapore, indicative that there is a lack of a self-sustaining population. Multiple reports of hybridising Yellow/Sulphur x Tanimbar Cockatoos are also strongly suggestive that individuals are struggling to find mates from their own species. Moreover, Sulphur-crested Cockatoos are more numerous than this species.

The following species were deleted from our checklist on the basis that there have not been any conclusive records in the nation for over 30 years.

Eurasian Teal, Dunlin, Roseate Tern, Hen Harrier, Plain Sunbird, Yellow-breasted Bunting, Eurasian Woodcock, Blyth’s Hawk-Eagle, Oriental Hobby

Shifted to Annex

This category houses species that have been recorded in the vicinity of Singaporean waters in the past 30 years. One should keep a lookout as there is a chance that these birds can be encountered within our national boundaries during pelagic trips. We keep an open mind about pelagic species and consider both quantitative (GPS coordinates) and qualitative evidences (descriptions of the sighting and ecological background of the species) when assessing such birds.

Lesser Black-backed Gull: A record from 20 November 2011 along the Singapore Straits with an unfortunate lack of GPS coordinates nor detailed descriptions.

Christmas Frigatebird: A single record outside Singapore waters from 4 May 2013.

Bird List Revision for March 2020

This is the latest revision of the Singapore Bird List dated 14 March 2020. The downloadable list (in Excel format) is available HERE.

The following are the major changes:

  1. Addition: White-cheeked Starling: – A single bird first reported at Picadilly, Seletar on 16 January 2020, which represent the first confirmed record for this very rare vagrant in Singapore.
  2. Addition: Brahminy Starling – Six past records of this species have been recorded in Singapore; on February 2008 (Marina East), October 2008 (Marina East), December 2003 (Bidadari), February 2016 (Punggol Barat), September 2016 (Gardens by the Bay) and January 2020 (Jurong Lake Gardens). A recently published paper (Soe Naing et al 2016) has indicated that this species is now a somewhat regular winter vagrant to Southeast Asia.
  3. Addition: Chinese Blackbird – A single Chinese Blackbird was seen and photographed at Jurong Lake Gardens on 11 February 2020. This is the most southernly sighting of this migratory bird.
  4. Addition: Oriental Turtle Dove – A single Oriental Turtle Dove was seen and photographed at Sisters’ Island on 28 November 2018 during an island survey. Details of this sighting only emerged recently.
  5. Deletion: Richard’s Pipit has now been deleted from the checklist. Upon further investigation and request for identification from pipit bird experts, the photos taken for that sighting is insufficient to positively identify the  bird as this species. However it is possible that it may be a very rare vagrant. The chase continues for this species.
  6. Other changes: The Malay names of many species have been updated in accordance to the latest revision by Mr Tou Jing Yi.

Bird List Revision for January 2020

The latest revision of the Singapore Bird List is now derived from IOC World Bird List ↗ Version 10.1. The downloadable list (in Excel format) is available HERE.

The following are the major changes:

  1. Addition: Taiga Flycatcher: – A single bird first reported at Singapore Botanical Gardens on 1 December 2019 represent the first confirmed record for this very rare vagrant.
  2. Replacement: Japanese Tit – The Japanese Tit replaces the misidentified Cinereous Tit from the previous record and sighting at Tuas South. Further sightings of 2 birds at Pasir Ris Park also on 1 December 2019, together with past sighting of this species at Chinese Garden on October 2011 further support its inclusion into the list.
  3. Taxonomic change: Eurasian Whimbrel – Whimbrel is now split into Eurasian Whimbrel and Hudsonian Whimbrel, and Eurasian Whimbrel is the expected species in the region.
  4. Taxonomic change: Black Bittern‘s scientific name changed to Ixobrychus flavicollis.
  5. Taxonomic change: Green Broadbill‘s family name changed to Calyptomenidae.

The sightings of the Blue Whistling Thrush at Fort Canning Park on 7 December 2019, and the White-cheeked Starling at Picadilly, Seletar on 16 January 2020 has been noted. No decision has been made on their inclusion into the list at present.

Bird List revision for November 2019

The third revision of the Singapore Bird List for 2019 is now available at our website. There are now 408 birds recorded in our list. The downloadable list (in Excel format) is available HERE.

There are four new species added in this revision.

Pied Stilt
2 stilts were first observed on 16 July 2019 at Pulau Tekong. Subsequent observations revealed a total of 4 adult Pied Stilts, together with 4 immatures. Nesting was observed with subsequent hatching of a further 3 chicks. Birds were observed at the location until 23 August 2019 when they subsequently disappeared. The closest location to Singapore for Pied Stilts prior to the discovery is in southern Sumatra.

Cinereous Tit
A single bird was seen at Tuas South on 5 November 2019 in the morning. The nearest population is in Kuala Selangor, Malaysia and Sumatra, Indonesia.

Fairy Pitta
A juvenile was seen and photographed near Dillenia Hut on 8 November 2019. Wintering population has been reported in Borneo.

Daurian Redstart
A male was photographed twice at Singapore Botanical Gardens’ Eco Lake area on 12 November 2019. This represent the third record for the species. Previous record of a female at Satay by the Bay in 2013 and a male at a private residence along Cashew Rd in 2014 were taken into consideration in accepting this record into the list.

The other change in this revision is a major revamp of Malay bird names as per communication with Mr. Tou Jing Yi.

Singapore Bird List 2019 Revision 2

Bird List Revision for March 2019

The latest revision of the Singapore Bird List is now derived from IOC World Bird List ↗ Version 9.1.

Changes are as follow:

  1. Addition: Black-headed Bunting – A single bird seen at Kranji Marsh/Neo Tiew Harvest Lane on 18th November 2018 (Martin Kennewell and friends). There are doubts about the condition of tail feathers, but the occurrence of other Black-headed Buntings during the same period including at least four on Mantanani Island off Sabah, Malaysia, one in Itbayat Island, Philippines and a couple in Thailand – makes for a compelling case that it’s a genuine vagrant. A search in the various bird shops did not yield any bunting species for sale.
  2. Replacement: Swinhoe’s White-eye takes the place of Oriental White-eye due to new revision on white-eyes taxonomy. (Lim, B.T.M., Sadanandan, K.R., Dingle, C. et al. J Ornithol (2019) 160: 1. Molecular evidence suggests radical revision of species limits in the great speciator white-eye genus Zosterops)
  3. Taxonomic change: Spoon-billed Sandpiper‘s scientific name changed to Calidris pygmaea
  4. Language revision: Chinese names of the following birds have been revised: Common Moorhen, Square-tailed Drongo-Cuckoo, Eastern Barn Owl, Plume-toed Swiftlet, Blue-winged Pitta, Buff-vented Bulbul and Black-crested Bulbul

The downloadable list (in Excel format) is available HERE.

Bird List Revision for November 2018

The fourth revision of the Singapore Bird List for 2018 is now available at our website. The downloadable list (in Excel format) is available HERE.

There are two new species added in this revision.

Large Woodshrike
A female Large Woodshrike was seen at Jelutong Tower on the morning of 22 October 2018. This species was reported as a former resident of Singapore until at least the 1940s in the Bukit Timah area. There were additional unconfirmed records in 1970 from Changi, unfortunately without supporting evidence. It is highly likely the species have been extirpated in Singapore for a long time, and the newly recorded bird is a non-breeding visitor to the island. Perhaps it is a post-breeding dispersant or a wandering bird.

Eurasian Skylark
A lone juvenile Eurasian Skylark was seen along the bund of Pandan Reservoir on 3 November 2018. Just a day before, a similar juvenile was recorded at Mantatani Island in Sabah, Malaysia.

Its inclusion to the Singapore list is not a given though. Various species of larks are sold and bought in Singapore. Although there is currently no evidence of juvenile Eurasian Skylarks being offered for sale, the possibility cannot be ruled out. However, the concurrent sighting in Mantatani does strengthen the case of the bird being a genuine vagrant. Furthermore, the seen bird’s feathers seemed to exhibit no abnormal wear which would indicate captivity. On balance, the evidence suggest that particular skylark is a good candidate for inclusion to the list.

Other changes in the Singapore Bird List in accordance with IOC World Bird List version 8.2 are as follows:

  1. Lesser Cuckooshrike has been reassigned to genus Lalage following Jønsson et al, 2010.
  2. Pallas’s Grasshopper Warbler has been reassigned to genus Helopsaltes following Alström et al, 2018.
  3. Moved Black-winged Flycatcher-shrike and Large Woodshrike to Family Vangidae.
  4. Resequenced Campephagidae (Cuckooshrikes) and Phylloscopidae (Leaf Warblers and allies) families.
