Nicely captured Robin.
Of the three options you offered, I think (a) is closest. It just seems to
me that the tail is angled more downward and leftward on the Saturday
photo.
Also, the tail of the prey indicates a Sugar Glider rather than a
possum.

Subject: [canberrabirds] Mystery of the Powerful Owl tail
feathers
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?
