The Raven pair that successfully raised 3 young in the tree in my yard
last July to February, still inhabit the tree every day and night. That
nesting was already well under way by this time last year. One parent
started building a new nest in September on the other side of Castley
Circ after the young fledged but soon lost interest, maybe because the
three young stayed around. The 3 young were last seen by me (and
recognised as such) in February. I have not noticed them building again
yet but they defend the tree. It is nice having them, except that I
frequently need to rewash clothes or wash the car because of their
perches being nearly above the wash line.

In the last breeding season, a pair of A. Ravens had a successful clutch
of two in a tree opposite my house in Deakin. The young birds dispersed
but the parents have spent the autumn and winter in the immediate
vicinity guarding their territory. Some four weeks ago, I recorded a
nest-building activity wherein both birds flew into the tree where they
had nested with bunches of sticks and leaves. They did not, to my
observation, use the material to build the nest or a new nest. It
seemed to be a signalling activity, pair-bonding (or perhaps a
reconfirmation of vows). The signal worked because the neighbouring
magpies and currawongs got the message and began harassing the ARs until
they flew off noisily.
I also saw an AR apparently depositing some treasure (I did not see what
it
was) in the foliage of a roman cypress adjacent to the nesting tree on
at least two occasions. HANZAB describes caching of food although it
does not mention doing so in foliage. But that is what the activity
looked like to me.
On the matter of late breeding, I saw a very young begging magpie with
attendant adult on ANU campus last week.

A Raven was building a nest this morning high in one of the Telopea Park
blue gums. More or less in the middle of the park - about midway between
the picnic area with the covered benches and the toilet block.
