Dead White-bellied Blind Snake (Typhlops muelleri), Jasper Cat Snake (Boiga jaspidea), Brown Tree Skink (Dasia grisea) at Upper Peirce
Location, date and time: Singapore Island, Central Catchment Nature Reserve, access road to Upper Peirce Reservoir Park, off Old Upper Thomson Road; 27 August 2016; evening.
Observation: A juvenile Typhlops muelleri of about 10 cm total length (Figs. 1 & 2) was found dead in water in a drain. It is believed to have drowned. A male example of Boiga jaspidea of about 1 m total length (Fig. 3), and an adult Dasia grisea (Figs. 4 & 5) are both flattened and dried roadkills found plastered on the surface of the road. They have probably been dead for more than a day.
Remarks: The three species of reptile herein recorded are recognised as rare in Singapore. Boiga jaspidea and Typhlops muelleri are classified as ‘critically endangered’ while Dasia grisea is regarded as ‘endangered’ (Lim, 2008: 264-265).
All three specimens have been deposited at the Lee Kong Chian Natural History Museum at the National University of Singapore, with Boiga jaspi
dea catalogued as ZRC 2.7225, Typhlops muelleri as ZRC 2.7226 and Dasia grisea as ZRC 2.7227.

Many-lined Sun Skink (Eutropis multifasciata)
Sungei Buloh Wetland Reserve, 5th February 2016
This carcass of a Many-lined Sun Skink was likely accidentally killed by an Oriental Pied Hornbill (Anthracoceros albirostris).
The resident male Oriental Pied Hornbill often seen at the Wetland Centre in Sungei Buloh Wetland Reserve has a habit of perching on a particular metal standee. Sometimes, when he takes off, he launches himself with such force that he tips the standee and it topples over. On this occasion, upon righting the standee, I discovered that a Many-lined Sun Skink had been crushed beneath. The unfortunate Skink had probably been basking or foraging on the ground when the Hornbill landed on the standee and then took off, causing it to fall over and crush the Skink.

Sungei Buloh Wetland Reserve, 11th May 2015
This flattened carcass of a Many-lined Sun Skink was found at the roundabout of the Wetland Centre; it raises the question as to whether vehicles are entering the roundabout too quickly, giving smaller creatures little time to escape.
Olive Tree Skink (Dasia olivacea) roadkill at Old Upper Thomson Road
Location, date and time: Singapore Island, Old Upper Thomson Road, near junction of access road to Upper Peirce Reservoir Park; 10 April 2014; 1415 hrs.
Observation: The observer was driving northwards along Old Upper Thomson Road, when a lizard was seen running across the road. It had exited the State Land on the eastern side and was attempting to enter the Central Catchment Nature Reserve on the western side. Unexpectedly, it ran straight under the front offside wheel of the vehicle and was immediately crushed to death. The victim, an adult of about 17 cm total length, was retrieved and later photographed, before being deposited as a voucher specimen in the Lee Kong Chian Natural History Museum at the National University of Singapore. Most of the scales on its dorsum were abraded during the accident (see accompanying picture).
Remarks: The largely arboreal Olive Tree Skink is rarely seen in Singapore, being known only from forest at the Bukit Timah and Central Catchment Nature Reserves, as well as on Pulau Ubin. It is regarded as an ‘endangered’ species in Singapore (Lim et al., 2008: 168).
