Ten years after Goh Si Guim’s article on the exhumation of Bidadari in Nature Watch 10.1, what has become of the place? How much of the site do we still remember and treasure today?

Careful recording by veteran birdwatcher Alfred Chia has documented over 140 Bidadari species (Chia, 2012), an impressive total for a piece of ‘wasteland’ that does not even contain remarkable water features. Birds are, undoubtedly, Bidadari’s main draw, but people from different fields also appreciate other aspects of the woodland concealed by its unkempt grassy fringes.
