Notes: Habitat - the calls were coming from emergent Grey Gums in Western Sydney Rainforest remnants along Blue Gum Creek, surrounding hillsides are open sclerophyl dominated by iron bark, turpentine and grey gum. I suspect this creek is an important corridor for these animals as my only local records and anecdotes I have heard from other local residents mostly relate to the slopes above the creek. It is under increasing pressure from water pumping and clearing.
Observation details - first calls were heard just before sunset on 22 Nov. This was a distressing wailing kind of call, very loud and carrying across the valley, which I think may be the female? I looked for the animal and narrowed the call down to a couple of emergent eucalypts by the creek but was unable to see due to thick midstory. After dark about 2000 there was the more familiar big cat type call which I assumed was the male. Calls were about every 20-30 minutes until about 2300. Last heard at 0300.
