Singapore Avifauna records on eBird

Five of the 27,000+ records uploaded to eBird from the old Singapore Avifauna newsletters. Photos taken in Singapore and elsewhere (credit: Raghav Narayanswamy and Keita Sin).

For much of my first few years of birding in Singapore, I wondered how the data from earlier eras in local ornithology could be made available for more to benefit; if early dates and late dates, major hotspots, past trends in the local avifauna, among other useful information, could be compiled in an accessible format for the community at large. After all, this small country has always been blessed with a higher-than-average observer coverage relative to its surrounding regions. The data could fill major gaps in understanding Asian avifauna, and be greatly beneficial to interested local birdwatchers as well.

So when I first saw that the Nature Society (Singapore) (NSS) had made its old editions of Singapore Avifauna from 1987 through 2010 available on its website, it was immediately clear that this could be a great resource for the birding community in Singapore if it could be consolidated into a more readily-accessible format. To really know how many times a species has been recorded locally, or which months it appears most frequently, manually scrolling through hundreds of reports for that species would not be practical. Rather, the data would need to be in a spreadsheet, and easily searchable, for the information to be most useful.

Recently, as Keita discussed last week, eBird has established itself as the most widely-used citizen science database for avian records. Many studies have referenced data stored in eBird to examine trends and achieve important conservation outcomes. It also reached a major milestone — 1 billion bird observations — in May this year, reinforcing its position as a powerful tool for conservationists and casual birders alike to share observations and further broaden our collective knowledge. It was clear to me that putting these important records from SINAV on eBird was the best way to make them as impactful as they can possibly be.

In collaboration with Singapore’s eBird reviewer Martin Kennewell, after obtaining permission from NSS to consolidate and upload the records, I set to work on designing a program to extract species names, observation counts, dates, and locations, as well as observer names for proper credit, for all the volumes of Singapore Avifauna available on the NSS website. Dividing this process into two steps: conversion of the PDFs (stored as images) into text, followed by extracting the important details from the text, I was able to upload over 27,000 individual observations, around 23,000 from Singapore and 4,000 from Malaysia and Indonesia.

The records uploaded now make up around 75% of all eBird records until 1990, and over 25% of all records until 2010 (the last year that Singapore Avifauna was published).

I can’t say that this journey was always smooth; one of the biggest challenges I faced was resolving old locations, with old place names, to current landmarks or points on the map which could be uploaded to eBird. With Martin’s expertise and support, I was able to resolve most of these, and sent a further few to NSS for their review. Additionally, some older editions of SINAV were missing; indeed, this was an era with limited technological access and keeping track of documents was admittedly more challenging than it has become today. Older records also suffered from a lack of specific counts; especially as birds that have now become rare once numbered in the dozens or even hundreds, observers sometimes may not have made the effort to accurately count these species.

See, for example, the entry for Sanderling in the report for February 1987.

This species is now barely an annual visitor; in the 80s, 90s, and even the early 21st century, counts in the double digits were regular. It’s hard to believe this count of 100 Sanderlings along with exceptional counts of other shorebirds, was just over 15 years ago.

Sometimes the work was tiring and it became difficult to continue, but I always knew the reward of making all these sightings accessible was worth the effort. In the end, after probably 100 hours of work, I uploaded the data to the NSS Records eBird account.

An example

The excerpts below are from Volume 19 (Jan-Mar) of Singapore Avifauna, published in 2005 (link). I’ve used this example to highlight how the process of digitizing reports into individual records works. For January, February, and March of 2005, Blue-crowned Hanging-Parrots were recorded a total of 12 times. Since the report is split into each of the months, this species appears three times.

These three entries are then converted into text with optical character recognition and combined into one overall entry for the period covered by the report, in this case January to March:

1 over Dairy Farm Road, 17/1 (LKS) and 18/1 (LKS) and 4 at Malcolm Park, 30/1 (NK/LKS/FR/IR/JR). At Botanic Gardens, 7 were counted on 4/2 (LKS) and 5 on 28/2 (AF/LKS). Also 3 over Nee Soon, 8/2 (LKS), 1 at MacRitchie Reservoir, 16/2 (LKS) and 28/2 (AF/LKS), and 1 over Dairy Farm Road, 24/2 (LKS). 1 heard at the foot of Bukit Timah, 12/3 (LKS), 1 flying over Dairy Farm Road, 22/3 (LKS) and 3 at Sime Road, 27/3 (LKS).

The individual records are then separated by looking for “sets” comprising the four important pieces of information for each record: count, date, location, and observer names. Of these, the most challenging to parse out is the location. In this case, there’s no extraneous information that we need to ignore, so it seems relatively straightforward to just use the leftover text as the location. But sometimes, sightings are associated with lengthy descriptions and the location needs to be extracted from that description – so I had to use natural language processing to pick out the location.

For the example above, the following 12 sightings would then be uploaded to eBird. This checklist shows how the first record (17 Jan) would appear in eBird’s outputs.

This project is mostly complete, and with it, thousands of bird observations recording hundreds of species have now been placed somewhere they can be accessed by researchers and amateurs alike. As more people come forward to contribute their sightings and share their knowledge, we can make more meaningful progress in conserving our valuable local wildlife.


This piece was written with the help of comments and advice from the Singapore Birds Project team (Dillen, Francis, Keita, Movin, and Sandra). My project drew on over a hundred reports made available by NSS on its website; their permission for me to take on this project also made this project possible. I also appreciate Martin’s contribution to many aspects of my project, including location-matching and manual approval/rejection of the uploaded records.

Extinction – what it means for birds in Singapore

Extinction is an evocative word, with some of the world’s most iconic birds such as the Dodo Raphus cucullatus and the Passenger Pigeon Ectopistes migratorius having achieved infamy for the dubious distinction of belonging to this category. Though the term often implies a sense of permanent loss, there are scenarios where extinction is not forever.

There are a few ways to think of the term ‘Extinct’.

The most commonly understood definition of extinction describes a complete global disappearance of a species. In Southeast Asia, no bird has been officially regarded as Extinct by the International Union for the Conservation of Nature (IUCN), though some species such as the Javan Lapwing Vanellus macropterus almost certainly are. The IUCN requires the criteria—exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual—to be satisfied before concluded that a species is Extinct. This is to prevent a loss of directed conservation attention for a species that may actually be very rare rather than gone forever.

A prime example of this would be the recent extinction declaration of the Ivory-billed Woodpecker Campephilus principalis, only made after 77 years after the last confirmed sighting of this conspicuous bird. Such long lag times between last sightings of a species and a formal extinction declaration is not uncommon, especially is species that have historically had large geographic distributions.

Another category is species that are Extinct in the Wild, with all known populations of the species known only from captivity. No birds from the region officially fall into this category, though the newly split Javan Pied Starling Gracupica jalla and Javan Green Magpie Cissa thalassina may qualify with further research.

In both cases, the declaration of extinction is fairly clear-cut. If the bird can no longer be found in the wild, then it will naturally qualify for one of the two categories. However, it is when we begin to incorporate national boundaries into definitions of extinction where things begin to get hazy.

Local extinction describes a scenario where a species is extinct, or no longer occurs, within a specific portion of its geographic range. In many cases, a species may entirely vanish from a country—a situation which we describe as extirpation. Many bird species are extirpated from Singapore. For instance, both the Great Slaty Woodpecker Mulleripicus pulverulentus and Moustached Babbler Malacopteron magnirostre have not had breeding populations in the country for decades (Wang & Hails, 2007). In these cases, extirpation describes a situation where a bird is no longer a Resident Breeder; even though occasional individuals may stray into our shores from elsewhere. The lack of a breeding population precludes them from being considered re-established.

Record Committees (RCs) are often the local authority for declaring a bird nationally extinct. However, since national boundaries do not present actual barriers to the movement of birds, this task is much more complex than it first appears. Birds that show up unexpectedly could represent a hidden, breeding population of a very rare species or merely visitors from across the border—how does one make a case either way?

In complex cases such as this, members of the RC will have to evaluate records on a case-by-case basis, taking into account the movement and breeding ecology of the species. Many RCs additionally comprise multiple people, so as to utilise a broad swathe of expertise instead of relying entirely on the knowledge of single individuals, whose judgment may be clouded by various biases.

Let us use the previously mentioned Great Slaty Woodpecker and Moustached Babbler as examples.

In 2018, a single, Great Slaty Woodpecker was sighted within Singapore’s central forests, staying for only a short while before disappearing. Though the identification of the bird is without doubt, Great Slaty Woodpeckers are conspicuous and noisy birds (Eaton et al., 2021) — it is unlikely that an undetected population has persisted unnoticed on a small island. In addition, large woodpeckers are known to move large distances when searching for suitable foraging locations (Ogasawara et al. 1994; Garmendia et al., 2006). A single bird flying the comparatively short distance from Johor to Singapore would be unremarkable when these woodpeckers are known to fly much greater distances. As such, taking the collective evidence into account makes us suspect that the Great Slaty Woodpecker presents a case where the bird is merely a visiting individual and not part of a larger, undetected population on the island.

However, the ecology of the Moustached Babbler and other understory babbler species such as the Fluffy-backed Tit-babbler Macronus ptilosus is far different. Anyone who has searched for babblers can attest to their penchant for hiding in thick cover and their reluctance to move into the open. This trait suggests that most babblers do not often move across large landscapes without forest cover (Yong, 2006). In addition, the relatively short, rounded wings of most understory babblers indicate that they are poor fliers and unlikely to undertake long-distance movements (Desrochers, 2010; Hermes et al., 2016). As such, if a population of a presently unrecorded babbler species were suddenly re-discovered in Singapore, we would not suspect that these birds were visitors from abroad. However, if these birds were encountered in a site that was regularly birded, we might suspect that these birds were recent releases/escapees. Babblers are highly vocal birds with distinctive calls and would surely have been recognised by local birders had they been present as a breeding population (Eaton et al., 2021).

As you can see, nothing is ever quite so clear cut!

These examples offer some insight into the thought processes that we might undertake when confronted by new records. Though it is a rather complex and multifaceted process, we hope that this article makes what seems like a rather opaque and fuzzy process much more understandable!

An Indonesian Archipelago Wishlist: Birds to Look Out For

The recent sighting of the Javan Plover Charadrius javanicus at a reclaimed site northeast of Singapore island was exciting yet unsurprising. Exciting because it was a first for Singapore and continental Southeast Asia that caught everyone off guard (then again, none of us are really prepared for megas!) and unsurprising because this is a species whose range has been slowly expanding over the years (Iqbal et al., 2011; Eaton et al., 2021). The appearance, and likely breeding of this species is highly relevant to recent changes in regional avifauna, especially when taking into account the first breeding records for the Pied Stilt Himantopus leucocephalus and Black-winged Stilt H. himantopus that were documented at the same site in 2019 and again this year, respectively.

Apart from the Javan Plover, several other species traditionally known to be from the Indonesian Archipelago (that comprises Sumatra, Borneo, Java and other Indonesian islands west of the Wallace Line) could potentially be found in Singapore and the neighbouring regions. Here are the distinguishing features of the Javan Plover and seven other species readers can keep an eye out for!

Javan Plover Charadrius javanicus

This species closely resembles the Kentish Plover, a locally uncommon migrant. Features including warm buff ear-coverts and relatively heavier bill and longer legs point to the Javan Plover. For those keen to learn more, detailed distinguishing features are described in Iqbal et al. (2013). Other regular plovers in Singapore can be distinguished by a combination of several other features. Lesser and Greater Sand Plovers have incomplete white-bands on their neck, Malaysian Plover have more “sandy-looking” upperparts, and White-faced Plover has a plain looking face as its name suggests.

Wandering Whistling Duck Dendrocygna arcuata

Although this species used to be an uncommon introduced species (Wang & Hails, 2007), the last local sighting was in 2016 (eBird) and the feral population has likely crashed for good. Being highly dispersive, wild birds could possibly wander here in due time. In fact, there is a record from Perak, Malaysia, that may conceivably be of wild provenance (but note that the current status of this species in Peninsula Malaysia is also introduced). It can be distinguished from the locally uncommon Lesser Whistling Duck by its lack of yellow eye ring and distinct white flanks.

Sunda Teal Anas gibberifrons

A species that seems to be undergoing a rapid range expansion across Borneo, Sulawesi and Sumatra (Eaton et al., 2016; 2021; Iqbal, 2016; MNSBCC Records Committee, 2016). With records in Sumatra not too far from Singapore, this funny looking duck might make its way here in the near future. It is much darker and browner than the local Whistling Ducks, with a distinct bulge on the male’s forehead. It prefers brackish water although other wetland habitats are also possible sites to look out for this species. Although various breeds of domestic ducks have been released in Singapore, these typically look more Mallard-like, with variable amount of colouration on their heads and wingpanels. Having said that, most if not all wild ducks in Singapore are typically worth celebration, so if in doubt of identification, it’s best to share the sighting for confirmation.

Black-backed Swamphen Porphyrio indicus

Swamphen taxonomy is rather incongruent, with much left to be discovered (Garcia-R & Trewick, 2015; Callaghan et al., 2020; Eaton et al., 2021; Gill et al., 2021). Records from Singapore are thought to be the Grey-headed Swamphen viridis (Wang & Hails, 2007; Callaghan et al., 2020), but possible integrades have been recorded before locally (Wells, 1990). The distribution of the Black-backed Swamphen is also contentious especially on Sumatra, with the two forms likely mixing (Wells, 1999; Taylor, 2020; Eaton et al., 2021). The Grey-headed Swamphen is another species struggling to survive in Singapore – a common theme for local waterbirds – and was last seen in 2018 (eBird). But if you do happen to see one, be sure to check its back colour. Black-backed Swamphen can be distinguished by having darker upperparts and face.

Australasian Grebe Tachybaptus novaehollandiae

The Australasian Grebe is capable of undertaking overwater dispersals (Llimona et al., 2020). Recent new records from Sulawesi and southern Sumatra (Eaton et al., 2016; Eaton et al., 2021) suggest a possible range expansion underway. Its habitat requirements are similar to the locally rare Little Grebe Tachybaptus ruficollis from which it can be distinguished by its darker neck and ear coverts. Given that the Little Grebe is already struggling to survive in Singapore at the moment, the chances of the Australasian Grebe breeding here like the plovers did are probably low, but they’re certainly worth looking out for.

Little Black Cormorant Phalacrocorax sulcirostris

Another species that seems to be experiencing a spread across the Sumatran coast (Eaton et al., 2021). Waterbodies – both coastal and inland – are potential locations to find this species. Locally, escaped individuals of the Great Cormorant and Little Cormorant have been documented (Wang & Hails, 2007). There were apparently two local records of the Little Black Cormorant as well in August and September 1993 (Oriental Bird Club, 1994; Lim, 2009). Assessing the provenance of cormorants can be a challenge in Singapore so do try to obtain high quality images of them (especially the legs) if you find one.

Little Egret Egretta garzetta nigripes

Knowledge on the distribution of this taxon in our region is far from ideal. Present from Indonesia through eastern Australia, it seems to be spreading across Sumatra (Iqbal, 2012; del Hoyo et al., 2020; Eaton et al., 2021). Their local status varies from “uncommon”, “sparing” to “probable” (Wang & Hails, 2007; Robson, 2014; Puan et al., 2020) and there is still much for us to document. Possible integrades have been seen in Singapore too. Various bare part colouration distinguishes this taxon apart from the locally common migrant Little Egret garzetta (Bakewell, 2019), perhaps most distinct among them being their toe colour – black in nigripes, yellow in garzetta in breeding plumage (images 14 & 15). However, caution should be taken during identification as juveniles and non-breeding garzetta can have duller feet and mud can affect feet colour (Robson, 2014).


Sacred Kingfisher Todiramphus sanctus

This species breeds in Australia and is a highly likely contender for showing up on Singapore given that it is an Austral migrant to Borneo and Indonesia, similar to the Horsfield’s Bronze-cuckoo Chrysococcyx basalis. Multiple people have claimed an encounter with this species in Singapore and it is also listed to be present in Robson (2014). However, none of the records have been adequately substantiated and a record from Thailand in February 2019 (Round et al., 2020) is the only formal record in our region thus far. The Sacred Kingfisher can be distinguished from the Collared Kingfisher T. chloris by its turquoise upperparts (as opposed to blue), smaller overall size and bill, and buff wash on its lores and flanks. Care is required in distinguishing this species from immature Collared Kingfishers as they can show some buff wash as well, but typically with scalloped plumage on their breast.

Nesting Malaysian Plovers

By Goh Cheng Teng
Edited by Keita Sin & Lester Tan

The Malaysian Plover Charadrius peronii is a small shorebird that inhabits coastal sandy areas and rocky shores. It is the only resident breeding plover in Singapore island and can be reliably found along the man-made seawall at Marina East. They are classified globally as Near Threatened (BirdLife International, 2017) and locally as Threatened (Lim, 2009).

A Chick!

On the morning of Sunday 27 June 2021, Lester Tan and I were walking along the Marina East seawall when we were halted by a soft twik from a male Malaysian Plover to our front. This was highly unusual as the Malaysian Plovers at Marina East do not typically vocalise, preferring instead to scurry away in silence.

With this thought at the back of our minds, we started scanning the area, locating a female Malaysian Plover slightly behind and below us in short order. We soon spotted movement from the female’s direction, which turned out to be an extra set of legs belonging to a very new Malaysian Plover!

As we approached slowly for better photographs, the female Malaysian Plover brooded the chick for a while (image 1) before running off, presumably to distract us from the chick. We kept our distance and the chick waited a while before getting up to follow the parent (image 2).

Growing up

Over the next three Sundays, we revisited Marina East to document the chick’s progress (image 3). Each time, we were first greeted by the soft twik of the male Malaysian Plover a distance away from where we would eventually find the female and the chick.

On 4 and 11 July, the weather over Singapore was rainy and the chick was regularly brooded by an adult, probably to aid in regulating body temperature (image 4). By 18 July, the chick had grown discernibly larger. While we did not witness brooding, it still sought cover from threats. Chicks of the Malaysian Plover are precocial and are never fed by parents (Yasué & Dearden, 2008) but we also could not observe any feeding behaviour.

Camouflage and Chick Defense

When disturbed, the chick tucked itself into the nooks and crannies of the seawall. Its mottled brown, white and black plumage provided camouflage while it nestled itself against pieces of marine debris (image 5). We also observed it hiding in grass adjacent to the seawall.

As long as we remained stationary at distance, one of the adults, typically the female, would eventually approach the chick while vocalising a series of soft twiks. The chick would then get up and follow the adult. We did observe brooding by the male as well, though less frequently.

While plovers are among the group of birds known for using the “broken-wing display” in response to disturbances (Gómez-Serrano & López-López, 2017), we did not observe this behaviour. We only observed them vocalising and attempting to lead us away from the chick whenever we ventured too close. Sometimes, an adult approached us while vocalising.

On one occasion when a flock of crows roosted nearby, the chick went into hiding while the adults kept watch from a distance. We observed an adult flying out to sea when dived on by individual crows although it returned to the site shortly after. However, when disturbed by humans, the adults did not fly off and always stayed within visible distance.


On Sunday 25 July 2021, we made our way to Marina East again. This time however, there was no twik greeting from the male Malaysian Plover. The female was nearby bathing and preening in one of the puddles atop the seawall. The pair of Malaysian Plovers had seemingly reverted to their typical non-vocalizing and more confiding selves, and the chick was nowhere to be found. The absence of the chick had been noted the day before, with adults reportedly being skittish (Francis Yap, pers. comms.).

The chick was independently discovered by Max Khoo a day before us on 26 June (pers. comms.), and would have been at least 28 days old, within the fledging window of 27-33 days after hatching (Wiersma et al., 2020). Unfortunately, we later found out that the plovers were preyed upon by a House Crow Corvus splendens, putting the journey of the young bird to an end.

Nest Habitat and Conservation

Malaysian Plovers nest in coastal locations that typically include an intertidal mudflat for foraging, a sandy beach for nesting, and a shrubby vegetated area that can provide cover for chicks during disturbances (Yasué & Dearden, 2008). Natural habitats suitable for the nesting of the Malaysian Plover are declining locally due to developments. However, many local nesting records have been on reclaimed land and coastal defense structures – they have previously been documented laying their eggs on the seawall (image 6; Nicholas Lim, pers. comms.).

The diet of the Malaysian Plover is poorly known (Wiersma et al., 2020) but we have observed them foraging on algal cover on the seawall where they appear to feed on invertebrates, or perhaps even microorganisms. Interestingly, they are rarely observed feeding on the adjoining mudflat where other waders have been observed.

Across five weekends of observations, this was the only family of Malaysian Plovers sighted along the entire stretch of the Marina East seawall. During the migratory season, presumably a non-breeding period, there would typically be more Malaysian Plovers scattered along the seawall, including multiple male and female birds. Their highly territorial behaviour (Yasué & Dearden, 2008) likely makes it difficult for multiple pairs to share the territory when nesting.

Our observations suggest that the plovers might be adaptable to nesting on artificial structures, provided that areas necessary for food, egg-laying and cover are present. Locally, breeding has been recorded in March-April (Lim, 2009) and July-September (BESG, 2006; Goh, 2016), as well as in June this year (Raghav Narayanswamy, pers. comms.).

The presence of these pockets of breeding habitat are crucial to the continued presence of the Malaysian Plover in Singapore. Protection and management of such areas from human intrusion during the breeding season where the birds are most sensitive to disturbances can be considered.

Rufous Barn Swallows in Singapore?


  1. There are several records of Barn Swallows with rufous underparts in Singapore
  2. Relationships between the different Barn Swallow subspecies are still being explored – we are uncertain of which subspecies the rufous birds seen in Singapore belong to
  3. In the meantime, please share your sightings if you come across any of these rarer migrants!

Migratory birds are slowly streaming into Singapore as the Northern Hemisphere winter sets in. One of the commonest species that share the local aerospace with the resident swiftlets and Pacific Swallows Hirundo tahitica is the Barn Swallow H. rustica. The Barn Swallows are easily identifiable from their distinct clean white underparts but did you know that rufous Barn Swallows have been seen in Singapore before?

There have so far been at least three documented records of Barn Swallows with rufous underparts in Singapore, one at Punggol Barat on 3 April 2016, one at Neo Tiew on 21 December 2019 and another at Neo Tiew on 20 January 2020 (though possibly the same individual spotted a month earlier).

The usual Barn Swallows that visit Singapore during the wintering months are of the subspecies gutturalis (Chasen, 1923; Gibson-Hill, 1950) with clean white underparts along with a distinct black breast band (Figure 1). It is currently still unclear which subspecies these rufous Barn Swallows belong to, but what the local community can do in the meantime is to make sure that these records are properly documented while researchers continue to study their relationships!

This article will become slightly technical from here onwards, but for those who have an interest in the biology of birds, read on!

Barn Swallow subspecies taxonomy is tricky; different authors have differing opinions on which subspecies are valid and the boundaries of their breeding ranges (Figure 2, Table 1). With regards to the subspecies that occur in Southeast Asia (and consequently Singapore), the International Ornithological Committee (IOC) recognises four subspecies, namely gutturalis, tytleri, mandschurica and saturata, while Birds of the World (BOTW) recognises gutturalis, tytleri and mandschurica too, but treats saturata as part of gutturalis instead. On the other hand, Dor et al. (2010) who has worked on Barn Swallow phylogeny lists two relevant subspecies, gutturalis and tytleri.

Table 1. A summary of the differing treatments of the Barn Swallow subspecies according to authors.

Of the supposed four subspecies that might occur in Singapore, only one is described to have creamy white underparts (gutturalis), with the other three (tytleri, mandschurica and saturata) have some degree of rufous on the underparts (Table 2).

However, on top of the difficulty in distinguishing underpart colours (what is the difference between ochre, rufous and chestnut?), plumage can also vary with individuals and wear (Dickinson and Dekker, 2001). More significantly, there is likely to be interbreeding between different subspecies in intergrade zones within their breeding range (Dickinson and Dekker, 2001; Nazarenko, 2016; Turner, 2006). For instance, there are some interesting swallows that are within range of tytleri and/or where tytleri overlaps with other populations (such as gutturalis) that are not entirely white or rufous, and some examples are listed here: a) western Mongolia, mostly white underparts with rufous tinge; b) central Mongolia, underparts with faint rufous tinge; c) central Mongolia, pale rufous underparts d) northern Mongolia, white underparts with rufous vent. Compare these with birds found further north (that are presumably tytleri based on range) such as this and this that are clearly much more rufous in colour.

As the ornithological community continues to explore the answers to the relationships of the various Asian populations of Barn Swallows in their breeding ranges, the verdict on the “rufous” individuals in Singapore is still open to interpretation. However this doesn’t change the fact that they are quite rare locally, so please do share your sightings if you manage to spot or photograph any!

Disclaimer: The authors of this short article (Dillen and Keita) have not been involved in any of the Barn Swallow studies. We dove into this topic confused and emerged out of it even more confused – please let us know if there are any errors!

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.
