I think this is still the one who came into the backyard on 11/6/23. There has been fresh poo under the tree every day since. Today is very windy and the koala is unco-operative, so photos are not fabulous.
Typical male calling but also has another call/sound at 16 sec, 31, 50, 53, 64, 75 sec marks, possibly a female koala responding? Original sound file has been amplified and edited.
