Rat (Rattus sp.)
Choa Chu Kang, 27th June 2011

This rat carcass was found on the KTM railway tracks that run through Choa Chu Kang. It might have been killed by a passing train.

This could be any of the following species of rat, which may be found in secondary growth and scrub in more rural areas of Singapore:

Oriental House Rat or Asian House Rat (Rattus tanezumi), formerly considered a subspecies of the Common House Rat or Black Rat (Rattus rattus)

Polynesian Rat (Rattus exulans)

Malaysian Wood Rat (Rattus tiomanicus)

Annandale’s Rat (Rattus annandalei)


Heron (F. Ardeidae)
Commonwealth, 21st May 2011

The remains of this bird were scattered alongside the KTM railway tracks which run along Commonwealth. I cannot confirm that the skull, legs, and the other bones all belonged to the same individual, although their close proximity is highly suggestive.


There are a number of smaller heron species that are commonly recorded in Singapore, and the skull could have belonged to one of these species:

Cattle egret (Bubulcus ibis)

Striated heron (Butorides striatus)

Chinese pond heron (Ardeola bacchus)

Yellow bittern (Ixobrychus sinensis)

Cinnamon bittern (Ixobrychus cinnamomeus)

Black-crowned night heron (Nycticorax nycticorax)
