I walked through Hyde Park this evening at dusk, and saw what first appeared to be large black birds circling around. Think a murder of crows. But they were a bit hunchbacked and then, looking straight up at the underside of one, its silloutte looked awfully reminiscent of the batman logo. Not a bird at all. Bats. Lots of them and huge.

I must say, the animals in Sydney sure are interesting.
