Atherton Tablelands, QLD, Australia
Part 2 : Victoria's Riflebird

I took over 3000 photos of Victoria's Riflebirds during September (and another 5000 in October!) so I thought I'd dedicate a whole page to them. All the photos here are from September...the October photos will appear on a future page...

Late September is the peak display period for Victoria's Riflebird, a member of the Bird-of-Paradise family and throughout this time I could usually be found watching one of their favourite display perches. I found over 10 active display perches this year but only a few of them were suitable for photography.

On one morning, while the male Riflebird was sitting on his perch minding his own business, a male Cairns Birdwing came and repeatedly dive-bombed him! I've no idea what triggered such a reaction as I've never seen a butterfly attacking a bird before...maybe the greenish-blue irridescence on the crown of the Riflebird fooled the Birdwing into thinking it was a rival male?

It takes around 7 years for male Riflebirds to attain their full breeding plumage. Prior to this they are pretty much indistinguishable from females except during display season when the immature males enthusiastically practice their display routines.

After the circular double-wing raise, the next stage of the display is the alternate wing stretch where each wing is stretched in front of the face in turn. The speed with which it changes wings depends on the male's level of excitement. If a female was present it could get quite manic...
