Steve,
I have limited experience of this species but Victorias Riflebird young
males will gather to practise.
They will even take turns at playing the female role in the display.
Occasionally an adult male will burst in on the scene and show them how it
is done. As some of the display involves the twitching which changes the
viewed colour of the refracted light on adults from green to blue (or v.v.)
I suppose that there is something in the colour of the feathers which we
cannot perceive.
I have seen an immature Golden Bowerbird do the sort of display you have
captured at a bower but never an adult and I've watched them a great deal.
There are also photos existing of this but not taken by me. Was this a
little cross species education?
Regards,
Alan

Subject: Immature Paradise Riflebird Displaying
Hello all. I just spent and interesting morning at Mt Glorious (near
Brisbane) chasing a few rainforest species for the year list. The
highlight was was seeing a Male Paradise Riflebird in full
display...something I've not witness before. The strange thing was, it was
an immature bird. Now, I know it takes a few years for them to reach the
fully black plumage, but I had just assumed they would wait until they
were all grown up before they started that type of caper. He seemed to
know what he was doing, and did manage to attract a couple of females to
the show. Trouble is they were the wrong species! (one each of Regent and
Satin Bowerbirds). I guess practise makes perfect. I've place a trip
report with pictures at http://aussiebirding.wildiaries.com/trips/10890
Cheers Steve Murray
