There are many studies of diet of PO over the years. (When I did my honours year, Sue Tilley was another student in my cohort who did one.) As for assessing these issues there is the possibility that perhaps smaller prey (if indeed they do) is eaten during the first night or where it is caught and less likely to show in pellets) and only the bigger prey are held for the next day at the roost, so such information may easily be biased towards bigger items. They are also known to sometimes take young koalas.

Many thanks everyone for the great responses to my comment.  John’s prey list repeated below and any other similar list will enable the hunting preference and success to be evaluated.  I agree, back young of Brush-tailed Possums are an alternative to ring-tails – at the smaller end of the medium-bodied mammalian prey and less dangerous than the adult BTPs. 


January: 1 ringtail; February: 1 ringtail, 1 sulphur-crested cocky; March: 0 prey; April: 2 ringtail, 1 sugar glider, 1 crimson rosella; May: 1 ringtail, 1 sugar glider; June: 1 sugar glider; July: 2 sugar gliders; August: 1 ringtail, 1 sugar glider.

Great shots Geoff. With my sparse knowledge of possums, I would have identified that as a brushtail.


I didn’t see Powl today or yesterday but there are fresh droppings and pellets below the 3rd tree from the street, besides the drain, on the club side. It was too dense to see into its upper branches, on a dull day.

In March I proposed the below as a young brushtail.  Any other views?
