Hi Denis,

Sedentary owl species such as tawny owl, typically sort out their
territorial boundaries post breeding season, during the dispersal
period of the young birds of the year. Peak calling is actually during
this time, which is generally autumn. They do call again at onset of
nesting but much less. So as various local birds here are now in their
autumn/winter mixed flocks, the magpies are singing and the
wattle-birds are making their autumn/winter calls, I would regard your
owl calling as part of autumn territorial behaviour. I have heard them
calling at this time before, I heard one the other night, and thought
nothing of it as it seemed normal, familiar owl behaviour to me. Many
species sort out their territories then, even if they leave for winter
quarters and come back they still have dominance in spring. And any
that can will remain throughout for as far as territories are
concerned, the holder usually has the advantage over intruders.

We need to get out at night more.
