This first images shows the 'suburb' of Karbeethong - about 5 km along the Inlet from the town of Mallacoota, with the green dot giving the position of the bat colony.
On our last evening it was very overcast and thus getting dark somewhat earlier. The bats were swarming by 2010. However, rather than heading straight out up or across the Inlet, for several minutes they appeared to circle as if unsure what to do.
By about 2025 things seemed to have settled down and, while some were still circling, others were flying off. As I had gone down the hill to get some photos I was able to notice that as well as the torrent heading NNW there was also a good number heading SSW.
A final comment is to note that Tammy is not at all happy to go anywhere near the colony. Whether it is:
- the noise - I can imagine she'd pick up a lot of the high-frequency echolocation calls as well as those audible to humans; or
- the smell - she mainly hunts by nose so is presumably pretty sensitive in the stink department;
