I can't say it is a reason for the difference but I would mention that
Lake Tuggeranong is much closer to the Murrumbidgee Corridor (Pine
Island) than is Lake Ginninderra. The birds that are in the area are
possibly going to stay closer to more real habitat. Plenty of waterbirds
at Pine Island. Although that could just as easily be argued the other
way around............

Hi All,
I took some photos beside Lake Tuggeranong yesterday, and I was
surprised by the absence of waterbirds. Lake Ginninderra in Belconnen
has lots of waterbirds as well as reed warblers. The habitat seems very
similar, yet the bird populations are very different. Does anyone have
any thoughts on why there would be such a difference? The main thing I
can think of is that Lake Tuggeranong has a lot fewer native trees
around the shores, and I don't think there's any islands for waterbird
habitat.
It still seems odd that with such a large body of water and reeds I saw
no waterbirds or warblers at all.
