My suspicion is that neither of the cygnets survived.
As indicated in my email of 1 July, one of them died in the last days of June. I saw the remaining cygnet several times over the first week of July but not since. Soon after that the adults seemed to largely abandon the pond - I saw one adult on the pond on perhaps only a couple of occasions over the ensuing two months.
Last Thursday evening (16 September) I had to dodge a freshly road-killed adult swan that was on the lanes of the southern side of the circle, suggesting it had been on its way either to or from the pond.
Over the weeks that the cygnets were present, it was clear that they were not restricted to the pond as sometimes they were there, sometimes not, and I assumed they moved between it and, most likely, Nerang Pool in Commonwealth Park. So I don't think inadequate food supply or quality in the pond was necessarily an issue in the cygnet's survival. I do think that it is a stupid place for swans to try to raise cygnets though, because of the traffic situation. If the adult killed last Thursday was one of the parents, there may not be another breeding attempt on the pond. Pure Darwinian speculation.

Hello Harvey,
Do you know if either of the cygnets there survived? I suspect they both perished because they couldn't get out to go to a better food source. If neither survived I think we should suggest to manager of the area that any nest there in the future should be removed.
