Striped Keelback (Xenochrophis vittatus) eating Asian Toad (Duttaphrynus melanostictus)
Location, date and time: Singapore Island, Jalan Bahtera in compound of Sarimbun Scout Camp; 9 December 2014; around 1600 hrs.
Observation: A Striped Keelback of about 70 cm total length was found freshly dead and in the middle of swallowing an Asian Toad. The accompanying picture shows the anterior part of the dead snake with the hind limbs of the toad sticking out of its mouth.
Remarks: The Striped Keelback is an introduced species in Singapore where it inhabits rural and suburban areas. It is known to feed on frogs and small fishes (Baker & Lim, 2012: 114). The present observation confirms that it also eats toads. The cause of the snake’s death is unknown.

Pellets from Tuas: 1. The Pellets
By Melinda Chan & Chan Yoke Meng, 20th February 2015;
The casting of pellet by certain groups of birds is not too well known– see here for more information. After swallowing their prey, these birds regurgitate the indigestible parts that were compacted in the gizzard in a form of pellets. These pellets collect on the ground below the trees where the birds normally perch. Ornithologists collect and study pellets to get information of what the birds had been eating.
Of late, Melinda Chan had been collecting these pellets while Chan Yoke Meng was busy photographing the Black-shouldered Kite (Elanus caeruleus) along the tree-lined avenue in Tuas.
The image of the the exposed pellet clearly shows the bleached bone fragments.
Together with the pellets on the ground were carcasses of half-eaten rodents.
