Stomper Mitch came across the carcasses of more than 10 bats in Lentor Avenue this morning (Jun 2).

He wonders what could be the cause of the deaths.

Said the Stomper:

“I found bats’ dead bodies scattered on the grass, pavement and road on Lentor Avenue this morning, 2 June.

"In total, there were more than 10 of them. I posted a few photos here. It looks like they have been dead for a day or two.

"What could be the cause of this? Pesticide or some other reason?”

These appear to be Asiatic Lesser Yellow House Bats (Scotophilus kuhlii). One possibility is that a bat roost in the area was cleared out by people using methods that proved to be lethal in the end.

Roadkill ‘revival’
Researchers at the Lee Kong Chian Natural History Museum preserve dead wild animals for study
By Regina Marie Lee, 18th June 2014;

He was waiting for the train at Paya Lebar MRT station in April when he spotted a “brown patch” on the East-West Line platform.

“I nearly stepped on this brown patch on the floor. On closer inspection, I realised it was a bat,” said Sean Yap.

The 22-year-old National University of Singapore (NUS) life sciences undergraduate was surprised, but quickly tried to salvage the carcass.

He said: “A train had just arrived, so my friend blocked passers-by from stepping on the bat as I used tissue to pick it up, and placed it in a piece of bubble wrap.

"I didn’t recognise the bat species, and it was smaller and more fluffy than the common types in Singapore, so I salvaged it for the Lee Kong Chian Natural History Museum (LKCNHM) at NUS.”

He has tried to salvage other road kill for the museum before.

It was indeed a bat not commonly encountered here, according to LKCNHM officer Marcus Chua. There is only one other confirmed record of this species – the Javan Pipistrelle (Pipistrellus javanicus) – in Singapore.

Mr Yap explained: “The museum is always on the lookout for specimens because it prefers not to kill animals that are still living.”

While a dead wild animal on the roads can be an obstacle or safety hazard for other people, it is a potential specimen for study for the LKCNHM’s researchers.

Mr Chua, 30, said: “In the past, people used to shoot and collect wild animals for studying.

"But as we experienced habitat loss and some species became rarer in Singapore, conservation became the priority. Recognising that, (researchers) rely mainly on salvaging dead animals for study.”

It is usually officers from the National Parks Board or friends of the museum who report road-kill sightings.

On average, the museum gets a sighting once every two months. They can be found anywhere, but, for mammals, especially at the periphery of nature reserves.

Mr Chua said: “Road-kill specimens are important because every carcass tells a story. Researchers can learn about where the animal came from. It could highlight the population…at certain locations, or tell us what sort of migratory birds are coming to Singapore.”

The DNA collected is added to a DNA bank, and chemical analysis done on the animal can highlight environmental pollution.

The Leopard Cat (Prionailurus bengalensis) was thought to be extinct in mainland Singapore, with the last reported sighting in 1968.

But one was run over by a vehicle in Mandai Road in 2001, showing that the species had survived in Singapore.

However, getting the road kill is always a race against time.

“It is a competition with the National Environment Agency,” he said, laughing. “They want to keep the roads clean while we want to get the road kill.”

Those who spot a dead wild animal can inform the museum on 6516-5082 during office hours, or e-mail

Javan Pipistrelle (Pipistrellus javanicus) at Paya Lebar

Location, date and time: Singapore Island, Paya Lebar, Paya Lebar Mass Rapid Transport Station; 4 April 2014; around 2300 hrs.

Observation: A male example of 32.3 mm forearm length was found dead on the train station’s platform. The attached figures show the dorso-lateral and the ventral views of the specimen.

Remarks: The specimen is preserved and catalogued as ZRC 4.9490 in the Zoological Reference Collection of the Lee Kong Chian Natural History Museum at the National University of Singapore. It is not known how the bat had died, but the skin on the right side of his abdomen was split open, indicating that he may have suffered a violent impact. It is possible that the bat may have collided with the rotating blades of the giant ceiling fans at the train station platform. This is the second confirmed record of the Javan Pipistrelle in Singapore (see: Chan et al., 2009). Both local records of this species are from urban areas.

Nearly stepped on what I thought was a hairball at Paya Lebar MRT platform, turned out to be a tiny bat! Had Jen block people from trampling while I collected the body in my sacrificed calculator bubblewrap

I couldn’t get clear shots of the sad little guy’s face, but I’m suspecting it’s a Bamboo Bat (Tylonycteris sp.).

Update: Bat has been IDed as a Javan Pipistrelle (Pipistrellus javanicus)! Thanks Marcus Chua!

Found this little bat last night – undamaged and had;t been dead long. Is it rare? Does anyone from RMBR want it?

Here’s a head shot of the bat – does this help with ID?

Sad to say that I found another bat today, in the exact same spot. Both are now with RMBR.

Sad to say I’ve found another dead bat in my garden. This is the third one now. Beginning to wonder why this is…

An update on the dead bats!
Two were Lesser Asiatic Yellow House Bats (Scotophilus kuhlii) and one was a Javan Pipistrelle (Pipistrellus javanicus).
I’ve since been told that the Javan Pipistrelle found a few days ago here is only the second recorded in Singapore in 100 years! I find that amazing – let’s hope there are more out there.

We thank Alison Wilson for helping us salvage these three bats that were found dead in the Tanglin Halt area. They have now been preserved and have joined over 500,000 specimens of the Zoological Reference Collection for research and education.

These bats: Lesser Asiatic Yellow House Bat (Scotophilus kuhlii) (left and centre) and Javan Pipistrelle (Pipistrellus javanicus) (right) hunt insects, and help to maintain a healthy balance of insects in the environment.

If you see a dead wild animal, please send us a message on the Raffles Museum of Biodiversity Research Facebook page, call us at 6516 5082, or email A photo or description of the animal, its general condition and detailed location would be most useful.

Collected 2 insectivorous bat and 1 cuckoo carcasses at Portsdown today. The specimens will be deposited in the Raffles Museum of Biodiversity Research and used for research and education. Thanks Alison Wilson for the alert!

This photograph of a dead bat was shared by Lynn Chan. Based on the coloration of the fur, and its apparently tiny size, my guess is that it’s an Asiatic Lesser Yellow Bat.
