Bird List Revision for June 2018

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

There is one new species added in this revision, the Great Slaty Woodpecker. Previously considered to be extirpated from Singapore, with 2 unconfirmed sightings at Changi in the 1970s. A female woodpecker was photographed at Bukit Timah Nature Reserve on 1 May 2018. The woodpecker was seen again feeding near the summit from 4-6 May 2018. A female (probably the same bird) was photographed at Central Catchment forest (along the pipeline trail) from 11-12 May 2018.

A white-rumped storm-petrel was also observed and photographed at a distance on a pelagic survey on 12 May along Singapore Strait. It is likely to be a Wilson’s Storm Petrel, but because of the distance involved, a conclusive ID cannot be obtained without totally ruling out other white-rumped storm-petrels. Hence the decision to withhold the inclusion of this species into our checklist until further sightings are reported.

Bird List Revision for January 2018

The latest revision of the Singapore Bird List is now derived from IOC World Bird List Version 8.1.

Changes are as follow:

  1. Addition: Little Stint– Two birds at Chek Jawa, Pulau Ubin on 21 September 2017 by NParks (David Li, Jacky Soh and Fadhli Ahmad)
  2. Addition: Verditer Flycatcher – A single bird photographed by George Presanis at Dairy Farm Nature Park on 9 October 2017 is the first confirmed record of the species.
  3. Addition: Booted Warbler– Single bird at Kranji Marsh reported on 10 December 2017 by Martin Kennewell and Richard Carden. An earlier sighting on 4 December 2017 of an unidentified warbler by Muhd Fadhil of NParks was subsequently confirmed to be the same bird.
  4. Taxonomic change: The local subspecies of the “purple swamphen” complex (subspecies viridis) is now treated as a subspecies of Grey-headed Swamphen instead of Black-backed Swamphen.
  5. Taxonomic change: Crow-billed Drongo‘s scientific name is now changed to Dicrurus annectens.

Bird List Revision for August 2017

We are pleased to publish the latest revision of the Singapore Bird List to include taxonomic changes based on the latest IOC World Bird List version 7.3.

The changes are:

  1. Replacing Glossy Swiftlet with Plume-toed Swiftlet due to split of the Glossy Swiftlet species complex (Rheindt et al. 2017)
  2. Change of genus name for Garganey and Northern Shoveler from Anas to Spatula (Gonzalez et al. 2009)
  3. Change of genus name for Gadwall and Eurasian Wigeon from Anas to Mareca (Gonzalez et al. 2009)
  4. Family Scolopacidae (sandpipers and snipes) resequenced to follow Gibson and Baker (2012)

The latest list in Excel format can be found HERE.

Bird List Revision for June 2017

We have revised our Singapore Bird List with the following changes:

The changes are:

  1. Addition: Ruby-cheeked Sunbird – 2005 record from Martin Kennewell
  2. Addition: Green Broadbill – 2014 records from Pulau Ubin (Keita Sin) and East Coast Park (See Toh Yew Wai)
  3. Deletion: Western Marsh Harrier
  4. Taxonomic change – Himalayan Cuckoo from Oriental Cuckoo

The downloadable bird list in Microsoft Excel format has also been revised for clarity, printability and accuracy.

A brief sampling of regional bird checklists indicate error rates ranging from 0.9% to as high as 5.5% (sampling English Names and Scientific Names only). A high proportion are typo errors, followed by outdated taxonomy for Scientific Names. To avoid such issues, we have minimised manual typing and linked our list directly to the latest IOC list for every records.

The latest list can be found HERE.

Minor checklist revision for April 2017

There have been some minor English Name as well as Scientific Name changes to be in sync with the IOC World Bird List version 7.2 published in April 22 2017.

The English Name changes are are:

  • Blyth’s Paradise Flycatcher from Oriental Paradise Flycatcher.
  • Rufous-bellied Eagle from Rufous-bellied Hawk-Eagle.


The Scientific Name changes are:

  • Ruff from Philomachus pugnax to Calidris pugnax
  • Broad-billed Sandpiper from Limicola falcinellus to Calidris falcinellus
  • Spoon-billed Sandpiper from Eurynorhynchus pygmea to Calidris pygmea
  • Buff-vented Bulbul from Iole olivacea to Iole crypta

First checklist revision for year 2017

We have made some additions as well as deletions to our checklist based on recent sightings or the lack of them.

The new additions are:

  • Jacobin Cuckoo which was sighted in December 2013 and on subsequent season in 2014, both at Lorong Halus Wetland.
  • Black Hornbill with a subadult male sighting in July 2015 at Pulau Ubin, followed by ongoing sightings of a female also at Pulau Ubin.
  • Bulwer’s Petrel sighting at Singapore Strait on a pelagic trip organized by photographers on 12 November 2016.

The following bird species were deleted from the list:

  • Black-winged Starling
  • Crested Myna
  • White-capped Munia
  • Java Sparrow

All four were introduced species that went feral but subsequently extirpated. Our reasoning is that there is no possibility of re-introduction from neighbouring region since they are introduced species. Any new sighting will have to be new introduction/escapees.

The following species have name changes due to taxonomic revisions:

  • Eastern Barn Owl, Tyto javanica, formerly Western Barn Owl as the subspecies javanica in the Malay Peninsula is now clumped with their Australasian brethren.
  • Pomarine Jaeger renamed from Pomarine Skua for consistency as their genetic relationship to Catharacta skuas requires confirmation.

Lastly, thanks to the effort of Tou Jing Yi, the complete Malay name for all the bird species in the checklist is now included. The Chinese name for the birds have also been updated to reflect changes since the last revision.

Local extinctions of Singapore birds

There is an interesting paper recently published in the prestigious journal Conservation Biology by members of two National University of Singapore (NUS) labs titled “A robust non-parametric method for quantifying undetected extinctions” that came to our attention.

In it, they presented a novel method of estimating undetected extinction, i.e. the type of extinction events that may have taken place without humans taking note of them. They applied this new method to all 195 breeding bird species ever recorded in Singapore over the last 200 years. Of this number, 58 (~30%) are known to have gone extinct. They project probably another ~10 species have gone extinct without ever being discovered, thereby providing a more realistic extinction rate at ~33%.

The extinction of one-third of our resident bird species over the years represent a significant loss of our biodiversity. The authors also project based on the data from Singapore, an additional 14-16% loss of bird species in the region by the year 2100 with current deforestation rate. Some of our favorite birds are already extinct in Singapore. More will join their ranks without further conservation efforts, and it won’t be long before they are gone for good in the region as well.

One of the interesting side product of this new study is a new, extensively vetted list of all breeding birds ever recorded in Singapore based on thorough literature reviews going back to the 1800s. Reproduced with permission at the bottom of this post is a table containing the bird list of current and extinct species. This data represent a best effort by the authors at the time of publication. This website will use it as a starting point to update its own list in the future.

Updates for January 2016

Although on the surface it seems that we have slowed down somewhat the completion of the write-up for the various species, the truth is that there have been a lot of work going on behind the scenes.

For example, we have now included where possible, the link to the IUCN Red List assessment page for each species. There are of course a few species without any such link. The simplest reason is that IUCN list is derived from the BirdLife International checklist, whereas our Singapore list is derived from IOC. There are differences in what constitute a species and their range between these two lists. The most apparent example is the Javan Myna in our Singapore checklist which is our most common introduced bird species. There is no Javan Myna in the BirdLife/IUCN species checklist because it’s lumped with the White-vented Myna that is very abundant in Indochina. So it is listed as Least Concern. Yet, the Javan Myna is a rare bird in Java (personal communications), its home ground. So linking it to the White-vented Myna IUCN page is not the correct solution, as that misses out the story of its decline in numbers.

On the bird photos front, we have as of today covered about 100 species, or approximately 25% of the bird species in our list. It’s slow work as uploading and checking each photo takes time, but we are getting there. Our back of the paper calculation shows that collectively there are 346 species in which photos exist of the species taken in Singapore. So a further 50 species were sight records only. That means we have to supplement these with photos taken elsewhere. This is especially true of the migratory waterfowls that no longer have suitable habitat to winter in our region. So our head writer See Toh is now in Tokyo looking hard for ducks to photograph!

In the meantime, the IOC checklist version 6.1 just came out. Our cursory checks shows no further taxonomic updates that affect Singapore birds. If there are any changes, we’ll hopefully be the first to cover it.

A Beach Stone-curlew from Bali. There exist a pre-digital distant photo of this species by Alan OwYong, and that is the only photo record of this very rare resident species in Singapore. So it’s necessary to supplement it with bird photos from overseas.

How the website began – Part 1 (the checklist)

When I started taking birding seriously in 2010, information about birds whereabouts and what sort of wild birds there were in Singapore was hard to get. At first I relied on Wikipedia which list out all the birds that have been seen, and where they are likely to be found. Forums like Naturepixels and NPSS where bird pictures were shared were also sources of information about the latest birds found. Soon after, Facebook groups started sprouting up and I joined a few. That took the interest to another level with latest sighting discussed in closed group free from prying eyes. Whatsapp chat groups soon replaced SMS and one can instantly know what’s the latest news about any new birds.

Social media and technology have totally changed the way one approach birding in Singapore. While fieldcraft and technique matters to the serious birders, one can do birding quite well with just knowledge of which Facebook group or Whatsapp group chat to join.For the lists of birds found in Singapore, the choices was rather limited for the longest time. There is Wikipedia and there is Nature Society’s bird checklist. The latter being more authoritative yet the nomenclature used was strange. Both were available in format incompatible with how I kept track of my own burgeoning bird count. I had mine in a relational database with easy sorting of birds and all the benefit that comes with it. Wikipedia format made it difficult to transfer all the birds into the database easily, and the NSS one was in PDF which was also needlessly difficult. Nonetheless one day I managed to write a script to convert the NSS checklist into my database format.

With that came the ability to easily find out which birds I do not have, their relative abundance, and the start of my picture database. More importantly, I started to do a Singapore Big Year in 2012, and it was important to keep a separate Big Year list to help me track my progress in that competition. With the help of the database, the newly incorporated NSS checklist, and a list of possible location for each species, data analysis became much easier and more powerful than the pen and pencil approach that others were taking.

All was good, except Javan Myna was a White-vented Myna, and an Intermediate Egret was a Yellow-billed Egret in the NSS checklist and a whole other list of strange names, and keeping track of these difference took up my time. So one day I decided the best way forward was to stick to IOC nomenclature as they publish an updatable world bird list, and painstakingly go through every entry in NSS checklist and convert them into IOC names.

With that completed, I joined Singapore Big Year 2014. Armed with a revised Singapore checklist, I was constantly updating the database with my bird count that year and my guesstimate of my rival’s species count. A running species comparison between my 2012 effort and the 2014 also let me pace myself better since my work load had increased since 2012. I was also able to track everyone’s progress easily once I keyed in their data. That’s what a database is meant for; to query out useful information. So much so that by mid-November that year, I already knew I was 5 birds ahead of my nearest rival and that was enough to win the competition.

My Singapore checklist proved very useful to me, and so I published it in Excel format since 2013 for others to use. Since then, the checklist had been continually updated with new features and capabilities. It seemed to me the basic usage for a checklist have changed over time. For example, I have never physically printed out the checklist because I don’t do data entry by pen and pencil. Therefore a checklist in PDF format did not make sense to me. At least in Excel format, one can cut and paste the bird name to search for more information elsewhere. I thought wouldn’t it be good if we can do automatic links to those those websites for each species? With that realization, I started providing those links. The rationale for putting in names in other languages was very simple, there were requests for them and it made sense.

With all these information already incorporated into the database, it seems logical that when we started the Singapore Bird Project, the database and the checklist it produced would form the foundation for the new website. I’ll talk more about the database in a later article.
