A post in the Bird Ecology Study Group blog reported how a dead snake, found along the road in Choa Chu Kang, attracted food (flies) for the Pacific swallows. In this case, as in nature, the carcass was "not wasted". At least the flies and swallows came before our efficient cleaners. But still, drive carefully. Snakes such as Banded Malayan Coral Snake, Keel-bellied Whip Snake, House Wolf Snake, and King Cobra have became victims of roadkills, which I believe is one of the biggest killers of this amazing animals.
