The feathers are absolutely from a Tawny Frogmouth. Now that
does not identify the killer but there are lots of options: owl, raptor, cat,
dog………. If there is a connection to possum, it may likely be
a Powerful Owl as the predator.

We live on 3 acres just outside Torquay in Victoria.
 There is of course quite a bit of activity at night but in the last few
weeks we have had 3 occurrences which have left us wondering.  The first
thing we found was a small amount of fur and an entrail at least 2 feet long,
and absolutely nothing else.  The second was a possum with a hole in its
side and no other damage.  Finally we found these attached feathers under
pine trees - again nothing else.  The feathers are 23cms long.  Any
suggestions would be much appreciated!
