Elizabeth, before the January fires I had a bower in my neighbours garden
and my observations showed it was attended pretty much all year round,
though possibly a bit less in summer.
Unless you see copulation (which I can't recall ever seeing) it has been
generally accepted that bower activity does not constitute a breeding
record.
The female does all the nest building and brooding, as well as the feeding
of young in the nest and once fledged.
They are very secretive about this - I've had a suspected breeding event in
my GBS for about a month (it's been chasing away currawongs etc) but I have
no idea where the nest may be as there is no regular pattern. A fellow
Chapman resident (one of the authors of the article below) has seen a
fledgling in his garden this month and then found the nest nearby which he
previously had no idea about.
Up to about 10 years ago I published a number of articles on the SBB in
CBN, one useful one may be CBN 28 (3) 96-101 (2003) which summarises known
SBB breeding to that time and also gives references to earlier papers. At
that time the timing for the breeding cycle was deduced to be November to
January, but chat line posts etc indicate it is probably wider than that.

Jack Holland

A bower bird is building a bower in the front garden of a friend's house in
yarralumla. Is this early? Is this a breeding event--building nest? but
then, it isn't a nest
