Sugar gliders have been reported from the Lower Sullivans Creek Catchment

which includes the current Powerful Owl roost site. The study area for that survey extended to the David Street wetland.


Viewing the owl this afternoon, as well as the tail of the prey animal you could see flaps of skin that could have been the gliding membrane of a sugar glider.

The nearest spot at which I have seen a Sugar Glider is 970m from the roost.

Looking at Robin’s two photo’s, apart from the obvious tail on one and apparently not on the other (is it obscured by the left wing which appears to be drooping slightly?), and I may be imagining things, but I reckon the eyes of the two birds are different and there is a clear pale “eyebrow” on the second photo that appears not to be on the first – this could be an artefact of the light. I am beginning to think that there may be two birds. If this is the case, where is the second bird roosting – it won’t be too far away. Also, how far did it have to go to get its latest meal, a Sugar Glider? All guesswork on my part. I will be interested to see what others think.

On Thursday I posted a picture of the Powerful Owl - and Con pointed out it was minus its tail feathers. The speculation was that it was molting. However, I went back just now (Saturday) after hearing it was munching on a possum - and took another photo that clearly shows tail feathers.

Theories: (a) Thursday's picture contains an optical illusion, (b) feathers have re-grown very rapidly, (c) a pair of owls sharing the same perch?
