Hi Simon,
I've had Satin Bowerbirds maintaining bowers in my yard for the last 10 years
or so.
The current male seems set on the current location but early on there was a bit
shuffling going on. A bird would appear to be settled on a site and then, just
as you describe, everything would disappear. A quick search of the yard would
find he'd shifted to another location.
The birds have used 4 locations in the yard, (two were practise bowers built by
immature birds), but there were two locations the dominant male preferred and
alternated between on what seemed like a seasonal basis. I got the feeling that
the bird changed due to changing vegetation cover (deciduous plants) on a
seasonal basis, although I can't verify that.
The site alternation was relatively predictable, but it hasn't happened for a
few years now.
I'd suggest looking around the general area to see what you can dig up, or
alternatively, if you have a bit of time, sit at the location you've mentioned,
and it's likely you'll hear activity at the new site (if it exists) to lead you
to it.
Kind Regards,
Allan Richardson
