Mike is of course referring to Melbourne.

Now the sight is common over the Bolte Bridge, Yarts Centre.....

Testament to two threatening processes created by human beings:

a) a proliferation of Silver Gulls feeding on human waste and some deliberate feeding (they also damage buildings - see Ian Temby's thesis);

b) light pollution (an unnecessary greenhouse gas cost at both these places - and many others where proper shielding would save money and light spillage) attracting insects to be killed by the gulls (including moth species where only the male flies), leading to a reduction in the diversity and abundance of insect species.
